Title: Crawler redo at 1/72
Post by: RichO on 04/15/2014 08:39 pm
HEY AGAIN ALL,

  Welcome to my new thread. The Apollo Saturn V Crawler scratch build out of styrene at 1/72 scale.

  If you guys have been following my Micro Artwork paper crawler build, This will be nothing new, accept that this build will be somewhat larger and built out of styrene. I plan on building this larger scale the same way that I built the paper kit, following the same instructions.

  Background: I have been working on the paper kit for about, not quite a year. However the more I get to the end of the build the more troubles I have been having with the paper medium. I live in the Puget Soud area of the NW. Being new to card modeling I did not take steps to protect the kit from the etxream humidity and rain here. (We had 10 inches of rain in March alone, with 100% humidity... I'm a fish!!) The paper medium is warpping and delaminating!! So what I decided to do was to rework the build out of a more stable material. This means that I now am using the paper kit as a dress rehersal and transfering all the build experience to the styrene build.

  I had a bit of a struggle at first thinking that I have spent all this time building this kit, I was just not happy with the way I have handled the build and the end results so far. So I thought, knowing myself, that I could not let things go on the way they were and be confident enough to show my build at model shows. And so, here I am, well into the redoux at 1/72.

  So once again here we go!

Post by: RichO on 04/15/2014 08:50 pm
The many frame supports to build the main Chassis. This is 0.5mm white styrene. I scaled up the paper weights to 1/72, and transfered all the different paper weights to the styrene.

Post by: RichO on 04/15/2014 08:55 pm
These next two photos are of the same piece showing a close up of how I rough cut the styrene. Then I go back and do the finishing of the parts. This includes filing and sanding untill I touch the black outlines of the print. Then all is cleaned and ready for install.

Post by: RichO on 04/15/2014 08:57 pm
This is the floor of the Engineers Controll Room. This is the first piece that I cut for the rework. I used acrylic paint for the floor to match the color of the original kit.

These next three photos are the start of the construction. This photo is the first frame part installed and the first tie to hold things in place.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/15/2014 09:00 pm
The center frame supports installed and tied.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/15/2014 09:03 pm
All of the center frame supports. These are all tied and also include the arms of the Corner Structures.

Applying the styrene weld.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/15/2014 09:13 pm
Three different views of the main Chassis all welded together. this is about a months worth of work. The first three weeks just cutting out the parts to this point. The styrene is somewhat thicker than the card stock and a bunch harder to cut by hand, so things are going a little slower. Altho I do manage to work on this build almost every day.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/15/2014 09:18 pm
SO, a bunch of photos for now. I'll post again shortly after a few day of work, and then more often. I'm finding that the actual construction is going much faster than the first time around, because I sorta know how things fit this time.

Have you ever considered buying a laser cutter? I know half the "fun" of modelmaking is the satisfaction of a really straight cut line or smooth curve, but you'd save yourself so much time.

If you can't afford one yourself, there may be a makerspace/hackspace nearby with one you can use. I've used one myself and it's almost magical how simple they make the cutting of arbitrarily complex shapes.

Post by: RichO on 04/15/2014 10:45 pm
CRISPY,
  Nice to read from you again, it's been a while. I'm retired and on a low income. This is what I do to keep myself intertained. Anything to do with modern technology is a bit to expensive for me. I can only spend as I go along. I have all the time I need to cut by hand, besides there is the "art" involved. Mybe later when I get real old I'll have to get pre cut parts.  Thanks

Title: Re: Crawler redo at 1/72
Post by: RichO on 04/16/2014 12:46 pm
  RON, You're right. This is going to much funner than the first build. I know where I made the mistakes before and where to slow way down and really take some time to rework this kit. It really deserves to be built as good as possible, and I feel much more confident about the outcome with this rebuild.

  TOM, hand over the bucks and you got it!!

Hello Rich, my busy Plastic man,

secretly and quietly he is starting now with the 1:72 crawler, this is a surprise! (http://www.raumfahrer.net/forum/smf/Smileys/yabb/shocked.gif)

Have you printed the parts on sheet? How did you do that and to what thickness is that possible? (http://www.raumfahrer.net/forum/smf/Smileys/yabb/undecided.gif)

Keep on this amazing beast, I stay tuned! (http://scaleworld.forenworld.net/images/smilies/zustimm.gif)

Title: Re: Crawler redo at 1/72
Post by: RichO on 04/17/2014 12:47 am
What a nice suprise, nice to see you here!!


  So this new build is going great so far as you can see. What I have done here is to go to my local printers and had the drawings enlarged to 1/72 scale and printed onto a thin print paper. I then sprayed a very lo-tac adheasive onto the paper sheets and "glued" them to the 16 x 24 inch styrene sheets. The spry adheasive is so "lo-tac" that once I have cut out the parts, I simply peel off the paper outlines, and it's ready for painting.


  As far as the styrene thickness goes, of course there are several different thickness depending on the particular parts to be built. The main Chassis here, I have chosen a 0.20 inch-0.5mm thick sheet. To get to this figure I simply measured the thickness of the paper kit and enlarged the figures to a 1/72 scale and then matched as close as I could to the Evergreen Styrene sheets. On these Chassis parts, I feel is just ever so slightly thicker that the enlargement should be, but once again I have to go with what the manufacture has to offer. I felt I would rather go a little heavyer than thinner. The only down fall is that the styrene sheets are a bit tougher to cut by hand, but also this makes the model really stiff and heavyer.

  Thanks for watching the new build, this should be much better than the original paper build.

You sir, are a crazy man.[1]

I was going to ask how you got the markings. Do you find the very thin paper hard to lay down without getting wrinkles and throwing your dimensions off?

1 - That's a good thing.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/17/2014 01:12 pm
LAR,

  The paper that I am using is thicker than tissue paper, but not as thick as construction paper. About the same as typing paper but not quite. I went to Kinko's and use the blueprint machine to print the outlines. I have not had any shrinkage problems so far and the patterns are staying in place. The print itself is the same as Mischa's original, just no color involved, just the black outlines, and enlarged to 1/72.

  BTW, how was that lego movie??

Did you process it to remove the images and retain the outlines? Or did Mischa? That seems like a lot of work to remove all the art...

  In order to obtain the outlines that Mischa has made available, you first need to purchase the kit. It's ony made available to kit owners.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/18/2014 12:55 pm
HI ALL,

  I have some more of the 1/72 crawler to show today.

  This build so for is going great. Much better than before, like I said: because I know where I messed up last time. Anyway a lot more cutting and some new photos.

  Photo #1, These are the rest of the pipe chord supports.

  Photo #2, These are the slots that the new cut supports fit into.

  Photo #3, This is a shot of the bottom befroe the pipe chord supports are installed.

  Photo #4, Here we have all the pipe chord supports installed.

  Photo #5, Another view of the top side with the pipe chord supports installed.

  After all the pipe chord supports have been installed, it's now time to brace the internal beam structures. The big difference so far from the paper kit is that the styrene is much stiffer. So I really don't need to install these however just like the paper, these do make the beams extreamly ridgid. I do like how strong these make the model feel, so I will follow through with the bracing installation.

  Photo #6, I will be using thes Evergreen 1.5mm angles to do the bracing work.

  Photo #7, And this is how I will install all the bracing. The bracing goes along the beam center structures and along any structures that can not be seen when the finish facing applied.

  Like most of you, it takes me three days to cut the new parts and then an hour to install them. So hang tight all I'll be back. Thanks.

Hi Rich,

your restart with sheet looks really cool, and you can see that it gives you back a lot of fun. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)

Nothing against paper model building, but that's all much more stable and easier to handle, and on top of that at this comfortable scale. That must just make fun, right? (http://scaleworld.forenworld.net/images/smilies/gut.gif)

Keep up the great job, this will become a monstrously powerful crawler for heavy traffic. (http://scaleworld.forenworld.net/images/smilies/zustimm.gif)

Oops, I wasn't trying to angle for ME getting the outlines, fair is fair, Mischa deserves payment for his work, I was just curious how you got them, whether you had to post process or what. Mischa did the work already, awesome.

LAR,  Mischa has also designed the MLP/LUT kit that goes along with the Crawler. I have heard that the MLP/LUT kit could have more than 20,000 parts!! Thats a lot of cutting!! Just not quite ready for release yet.

Post by: RichO on 04/25/2014 06:00 pm
HEY ALL

  Materials hve been recieved and the construction continues.

  This first photo is the bottom frame just partly cut. This also shows how I printed the model parts onto a thin paper and then mounted these onto the styrene sheets. When the parts are cut out and ready to install, I simply peel off the paper kit parts and then install like normal.

  Photo #2, Is the entire bottom frame plate cut and ready to install. This cutting process took several day to cut and prep.

  Photo#3, Here are the center webs of the bottom beams. I will install these standing up straight and will be under the finished bottom frame plate. Then the box beams will be installed.

Keepm watching all, Thanks!

Hi Rich,

well then you have to do so for some years, and the paper crawler shrivels sulking in the corner ... (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cry.gif)

Post by: RichO on 04/26/2014 07:24 pm



HI ALL,
 
  Just a couple of photos today. These photos are of a few days work. These days I was building the webbing supports for the "I" beams on the bottom of the Crawler. The "I" beams are more numerous than the box beams and do most of the support work on the bottom side.
 
Photo #1,  This is view down the bottom side from side # 1. Here all the webbing has been installed and test fitted.

  Photo #2, In this view I have test fitted the bottom plate over the newly installed webbing for the "I" beams. All looks good, so now to the box beams.

I will now go around all the webs and make sure that all are secured and alligned and look good under the bottom plate. Thanks for watching.

Title: Re: Crawler redo at 1/72
Post by: RichO on 04/28/2014 01:21 pm
OK ALL,

  Some more of the box beams.

  All the webbing for the "I" beams have been installed, and now the "box" beams.

  In photo #1, You can see the start of the box beam construction.

  Photo #2, Here you can see that the box beams are the diagonal beams. The I beams run north and south, and the box beams diagonals. I will leave the box beams open for now, so I can use them for the electronics chapter.

  Photo #3, In this shot you can see the bottom top plate, or cover plate. This is how the bottom side will look when it is all sealed up and finalized.

DAVE,

  This build feels so much better than the paper build did. The styrene feels much more permanant, it's not affected by the weather, and just feels stronger. I'm having a much better time with this build.
Title: Re: Crawler redo at 1/72
Post by: RichO on 04/29/2014 11:09 pm
HEY ALL,

  I have finished up installing the beam section of the build.

  Photo #1, In this photo you can see how the box beams on the top side have been built. The beams running down the side of the crawler are to help support the external Chassis Frame. The box beams on the inside also have the webbing for the Pipe Chord supports.

  Photo #2, Here you can see the finished beam section for the top side. The diagonal box beams for the main roof support, and the box beams running down the both sides. All to support the roof and load.

  photo #3, This is how things look as all finished. The beam section is now over and I will be moving on to the construction of the outside finishing frame. Just a few pieces of external skin to install. At this time of the build the Crawler Chassis is now 24 inches long, (62 cm).

  Photo #4, Parts for the internal structures. Fans, Vents, Fuel Tanks...ect.

  Photo #5, Parts for the fuel tanks. I need to finish build the 2000 gallon fuel tanks and fully paint these before I can install them. The Fuel Tanks need to be installed before I install all the Pipe Chords or there will be to many items in the way to install.

  Thats all for today. I'll be back shortly, Thanks!

HEY EVERYBODY,

  So for today I have finished the skin install. I just had a few pieces to install before I move to the interior.

  In the first photo are the parts for this install. The braces on the right side of the photo are to support the loose edges of the skin.

  Photo #2, and #3, This shows the bracing mounted into place. I had eight of these to install.

  Photo #4, This shows the side skin mounted into place. You can see how the skin mounts to the bracing to create a nice clean edge and a strong support.

  Photo #5, This is a view of corner "A". This shows how the skin wraps around corner "A" and is the finished skin for the corners. These will be visable on the compleated model, so all is straight and clean.

  Now I get to move into the interior. Next is the feul tanks and the floor grates. All the small fun stuff!!
That all for today. Stay tuned!! Thanks.

The mounting gear on the top is temporarily in place so you can see how things look outside the crawler.

  I have another tank to build and then the floor grates and Pipe Chords. Thanks for watching all.

Hey Rich:

Looking good.

I have to ask you.  is all that detail visible when the crawler is fully built?   I have to admit i haven't looked at the real crawler at all.
Title: Re: Crawler redo at 1/72
Post by: RichO on 05/06/2014 05:04 pm
So now, for the next few days I will be installing the rest of the Pipe Chords. Then I get to do the first round of painting. I will make sure all is secured and installed permanantly and then off to the paint dept.

  Thanks all for watching!

Hey Tom,

  This model has a removeable top to it, so Yes, you can see all the detail. Altho the space on the real Crawler is cramed with machinery. I will attempt to resurch this later and build some sort of representation of the engines, pumps, tanks...ect. I really love this design because you can see all the details

These next three photos are of the maine frame with all the Pipe Chords installed. I have also started preping for the Paint Dept. The screens have been removed and the Engineers Controll Room floor has been masked for painting.
Title: Re: Crawler redo at 1/72
Post by: RichO on 05/14/2014 06:34 pm
I have left this section of the Pipe Chord install open so I can slip the Fuel Tanks through this gap, and finish with the Fuel Tanks. I have to spray the basic grey color and then install the Fuel Tanks.
Title: Re: Crawler redo at 1/72
Post by: RichO on 05/14/2014 06:36 pm
Here is the basic grey color. Now I will go back and hand paint the light grey onto this basic color for a subtle contrast that will match the paper kit just right.

In these next shots, you can see the Fuel Tank install. I have closed up the Pipe Chord ends and have sealed the Fuel Tanks into place. I have also finished with support structures that hold the Fuel Tanks into place and secured.

Hi Rich,

you are posting like a champion, compliment, but you know the processes also already by heart from your paper crawler, which is a great advantage now. (http://scaleworld.forenworld.net/images/smilies/zustimm.gif)

That looks already great so far, and also as a painter you have great talent, keep going like that. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)

MANFRED,

  Thanks for the pat on the back, it feels good.

  I think because I have already built this out of paper, the progress is slower but the build is going a little faster, if that makes any cense. The styrene is much slower to cut and prep the parts, but I already know how things fit together so the build is much faster. It's all good tho, and I feel much more confident about this build.

  Also I have learned from you, that I get a much better responce to the postings if I post when I do anything that adds to the build, posting every day or every other day, instead of once a week or more. I saw how people responded to your postings when you post frequently, so I have changed my posting to more often, Thanks.

HI ALTOGETHER,

  I have mostly completed the painting. I still look and find little things that need painting tho. I have to deal with a bunch of slackers in the paint dept.

  So now the start of the outriggers for the Cabs and JEL Tube supports. This is a photo of the parts for the four corners.

Title: Re: Crawler redo at 1/72
Post by: roma847 on 05/18/2014 07:43 am
Hi Rich,

thats right, the cutting and finishing of all the styrene parts means more expense than with paper templates. But everything is much more stable this time, and that's very important, especially for the construction of the outrigger structures. (http://scaleworld.forenworld.net/images/smilies/zustimm.gif)

Your are on a good way, keep on building and hang in there this time, I stay tuned. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)

You're kind of a nut. In a good way.

Are you facing any challenges when you have to "blend in" newly added subassemblies (like the corners) to already painted sections? How do  you avoid layering multiple layers of paint on the already painted parts?
Title: Re: Crawler redo at 1/72
Post by: roma847 on 05/26/2014 09:25 pm
Hello Rich,

Your paper version was very impressive, however the plastic has a more "sturdy" dimensionality to it that looks just spectacular.
Title: Re: Crawler redo at 1/72
Post by: RichO on 05/28/2014 01:03 pm
LAR,

  The layering in of new subassemblies is quite simple actualy. Working with the styrene and painting with acrylic paint is simply a matter of preping the site for the new parts and mounting them into the permanant location before I "weld" the parts into place. The weld fluid is, methylene chloride, and once I have the parts secured into place, I then apply the fluid with an insulin seringe to the exact spot where the weld is needed. The methylene chloride then seems to melt the acrylic paint out of the way and then melts the two parts together. I almost do not have to retouch the paint, as long as I'm carefull about my application.

  As far as layering the the paint goes, I just don't worry about it! The texture that I'm after really supports multi layering of the paint. The idea is to copy the multi layered paint that exists on military equipment and vehicles, which seems to have about a hundred layers paint. If you have ever seen a battle ship up close and personal, you know what I mean.

  Thanks for following along, your continued support is greatly appreaciated.

BRIGHTLIGHT,

  Thanks for the nice words.

  You should feel the difference!! The paper model was sturdy enough, but very fragile. A bump here or there and parts would tear off, or delaminate, and always the humidity and moisture. The styrene build is welded into one solid peice and I can stand on it and it won't crush. Very stabe, very strong!! I'm now convinced, styrene is the only way to build.

HI ALL,

  The building of the outrigger section is now finished, mostly. I still have a few things to do, but I will have to finish these things latter down the road.

I'm to the point now where I will send the build to the paint dept. I found a few spots with the Pipe Chords and the main Frame that need a touch up, and then painting of the outriggers will finish the Main Frame. This should only take a day to finish. Next I will be moving to the interior walls. At this point the build  is now 21.25 inches long, and 16 inches wide. This is just shy of the finished size. The Trucks will extend the width by about 1 inch over all. It's nice to get a good idea of the total overall size, so I can plan on displaying and traveling with it to the model shows.

Thanks all for following along!!

HEY ALL,

  Well the painting of the outriggers is now finished. However, my wife's laptop went black screen and now I can't post any photo's for a few days while the HP is being serviced. The painting of the outriggers looks good and unites the chassis frame into one unit.

  I'm now starting the interior build with the Chassis Walls. I have an opportunity to add some details here, and all must be painted before installing. I'll take plenty of photos to post when the laptop is up and running again shortly.

  Tune in again for the interior build. Thanks All!

Hi Rich,

I like your new details, as the floor grates, interior walls, access doors, and especially the windows of real glass.  (http://www.britmodeller.com/forums/public/style_emoticons/default/analintruder.gif) This is a beautiful indoor decoration, which costs a lot of time, but the effort is worth it. (http://www.britmodeller.com/forums/public/style_emoticons/default/coolio.gif)

When do you start with the lighting, I'm curious. (http://scaleworld.forenworld.net/images/smilies/gut.gif) But it's true, yes you have only the interior work to complete and all have painted. Only then you can install the LEDs. This is this time a difference from the paper model. (http://www.arcforums.com/forums/air/public/style_emoticons/default/70.gif)

Thanks for the nice words! As you can quess, I still have months of work to do befor the lighting can procede. I have to finish the interior walls of course. And then I  have to build all the interior fans and vents.  And also the Engineers Office space needs to have the furnature and controll computers installed. I need to do all this first so I know where the location of the wire runs will be placed. Also, because this build is so large, I am considering metal wire way hangers for the wire runs, just to add to the realizm. Thanks!!

  Here is a photo of all the fans together befor installing. Each of the big fans has 102 parts to build. The smaller fans have 70 parts each to build. Thats 790 parts for these 9 fans!!

  So the fan phase of the build is now over, but I have to move on to the next part of the build, which is (wait for it...) more fans!! I now have to build the Water Cooling Radiator fans. I have four of these to build, so maybe another month to build these, ( i hope it dosen't take that long tho).
 
  The Radiators have fan boxes, electrical motors, pullies, belts, and a lot more to deal with. I should be able to build one a week or so...

  The build continues.Thanks All!!

Hi Rich,

very nice update for the Water Cooling Radiator, especially the tiny motor is an excellent miniature and and I like it.  (http://www.britmodeller.com/forums/public/style_emoticons/default/speak_cool.gif)  But you have forget to install the V-belt, so the fan can not run. (http://www.britmodeller.com/forums/public/style_emoticons/default/analintruder.gif)

Joking aside, (http://www.britmodeller.com/forums/public/style_emoticons/default/goodjob.gif)

BTW, has Mischa also templates for the huge diesel engines in his Paper Kit?

(http://members.optushome.com.au/paylward/images/crawler/ctengine.jpg)

I would not be surprised if you put the other motors and generators also want to build, right? (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)​

BTW, mid-2012 one of NASA’s gigantic crawler transporters got an overhaul and was receiving new engines and other improvements that will allow it to carry the future Space Launch System (SLS) rockets. I have found some interesting photos, maybe you know.

Here the old diesel engines being lifted out of the crawler,

and so appears the new generation of diesel engines.

Last but not least, the coloring is always a matter of taste, and here the artist should, however, be granted the freedom for changes. (http://www.arcforums.com/forums/air/public/style_emoticons/default/377.gif)

Personally, I primarily orient myself to the original real thing, as you know. (http://scaleworld.forenworld.net/images/smilies/gut.gif) In this point, your approach is maybe then more an interesting demonstration object than the real thing and your individual painting is a nice stylistic device in order to emphasize certain details in this way, why not.

MANFRED,
 
  There is a vicious rumor about, that Mischa is going to do all the interior componants at a later date. I think this would be so cool. The interior is full of engines, motors, giant liquid storage tanks, generators, pumps...etc. However I am having a real hard time finding photos of the Apollo era interior, so I sure hope Mischa can find them and maybe produce some patterns to look at, but I'm not sure if that is a priority any time soon. You know me, I'd love to build these and install 'em.
 
  I have most of the photos I could find, and more as I go along with the build. The new engines and water cooling radiators really do not look like any of the Apollo era stuff, so not much of a reference item there.
 
  I am a big fan of artistic freedom. I had artistic parents, and I had an entire art career of nearly 30 years as a pro artist, so this is quite important to me. Besides, it's my model damn it!  LOL
 
  Lastly, GO TEAM GERMANY!!!  I should be rooting for an American team, but I don't know anybody that is wanting Argentina to win.

Post by: RichO on 07/17/2014 12:19 pm
HEY ALL,
 
  A quick update today. The build is going slow the past week. We have had a new member join the family this week ( baby boy, not mine). The tempeture outside has been nearly 100 degrees for days now, and I was at a critical junture on another build that I needed to get past.
 
 Just this one photo for today. These are the parts for three more Water Cooling Radiators. These parts are for the fan box's. I had to slow down my cutting technique somewhat, because the parts are very thin and delicate and I really wanted these to stay in one part. The parts are to be applied the same way as the first radiator build, so no difference there. Just a repeat pattern.
 
 More photos later, Thanks All.

  HEY ALL,

  IT'S time to wrap up the fan chapter of the build.

  The radiator build continues and is now finished.

  Photo #1, The electric motors all built.

  Photo #2, The four radiators altogether.

  Photo #3, The four Wtater Cooling Radiators back side with the motors painted and installed.

  Photo #4, Two of the radiators installed into the crawler.

  Photo #5, Another shot from above of the two radiators installed.

  Photo #6, All the fans together.                                                                                                                 

This represents a month and a half of fan building. The fan chapter is now finished, and next I get to move on to the fresh air vents. I do have a few items to finish up installing. Screens and blocks. I'll take brief photos of these odds and ends before moving on to the Fresh Air Vents. Thats all for now. Thanks All!!

So a couple of photos that should have been in the last postings.

  Thes two photos are of the Water Cooling Radiators. Trying to find Apollo era photos can be chalenging sometimes. Especialy of mundane equipment like fans and such. The two radiator shot are of the shuttle era radiators. However, on closer inspection you will notice that the radiators are not that different from the Apollo era radiators. In these photos you can see the electric motors and the Fuel Tank space that these radiators are located in.
Title: Re: Crawler redo at 1/72
Post by: RichO on 07/29/2014 10:06 pm
OK ALL,

  More for today! This is the Fresh Air Vent section of the build.

The Fresh Air Vents are a simple air exchange between the engine room and the outside air. As you can see in two photos, that the vents themselves are simply a hole in the floor that is covered by a safety screen so no one falls through. In these photos you can see that their are no filters or baffles to impede the air flow. Daylight can be seen easily through the screen to the outside.
Title: Re: Crawler redo at 1/72
Post by: RichO on 07/29/2014 10:11 pm
The building of the vents is straight forward and easy to build. Like oaa thinf modeling tho, these can take some time to build.

  Photo #1, The parts.

  Photo #2, more parts and the parts for the first vent.

  Photo #3, the directinal fins instalation.
Title: Re: Crawler redo at 1/72
Post by: RichO on 07/29/2014 10:17 pm
More photos!

  Photo #1, The screen installed from the top side inside the engine room.

  Photo#2, The vent has been installed from the bottom side. It's secured into place and will be painted when I build the underside later.

  Photo #3, This is the installed vent. As you can see, it looks aa lot like the oeiginal photo. the screen covers the hole and you can see through the vent to the fresh air outside.

  I have eleven more of these to build and onstall. I'll be back later with the final install photos. Thanks for following along!!

Hi Rich & Manfred,

                     I really Enjoy Seeing these builds ! When I was a young boy, my dad brought a birthday present consisting of the Coast Guard Training Tall Ship, The USCGC Eagle ( WIX-327), my cousin Graduated from the New London, Connecticut School there and was on hand for his Graduation...Loved that Ship...A 295-foot (90 m) sailing barque used as a training ship for Coast Guard Academy cadets and Coast Guard officer candidates. She was originally built in Germany as Horst Wessel, and was seized by the United States as a prize of war in 1945.

Took months building that model Circa 1964...and then off I was on building Cars, Airplanes and of course Space Ships. Wish I had saved some photos, but alas, they are all gone ..

Thanks Again for Sharing your Builds, Dave

Thanks MANFRED,  of course you know that the parts are only going to get smaller, and it only end when we die.

DAVE, Nice story! Mine is the same story but the ship was different. I started with the "GOLDEN HIND", and naturally I made a mess of it. '64 or '65 was the year and I never looked back. All trains, planes, and automobiles, with monsters ans spaceships. I love this!

  Photo #1, This is the switch that I will use. This is a four x switch for four "zones" for the lighting chapter. Tha power source is a regulated power box. The lights that I will use are so small that it takes almost no power to run these.

  Photo #2, Switch test, and light test.

I constructed the spot shields like this. I first cut a small length of 1/8 Evergreen tubing, and then cut a 60% angle. I then cut a small piece of 3/32 tubing. I drilled out the 1/8 tube to accept the 3/32 tube. I then drilled out the 3/32 tube so the light chip would clear. I then just slid it all together.

MANFRED,
 
  The size of the plug is small, as you can see. This is the only plug that I have in the system. I just have to decide which zone goes to which switch. Everything else is simply connections.

HEY ALL,

  More photos of the lighting install.

  Photo #1, Many parts for the single lamps.

  Photo #2, The rest of the single lamps for the interior.

  Photo #3, All the lights get a test befor I install these into the light shields.

  Photo #4, All painted and drying.

  Now I just have to install the rest of these and wire them together. I will do another light test to make sure that all servived the install process, and then the final wire twisting and placement to finish the interior lighting. More photos later. Thanks All!!

Hello Rich,
I am amazed at your finger dexterity, all the miniatures you have built very nice, (http://scaleworld.forenworld.net/images/smilies/zustimm.gif) but the steering wheel you might have built separately at this scale, isn't it? (http://www.britmodeller.com/forums/public/style_emoticons/default/yikes.gif)
Do you want to sand the edges still a little before painting, or should be covered by the color? (http://scaleworld.forenworld.net/images/smilies/gruebel.gif)  I know that this would be very difficult for the small parts, but it surely would look better. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)
On the drive console I would try it anyway, maybe the seat armrests would break off, showing that the ice is very thin ... (http://www.britmodeller.com/forums/public/style_emoticons/default/analintruder.gif)

But this is probably the only disadvantage compared to your first paper construction, because there are no such edges, if it is glued clean.   

Everything has advantages and disadvantages ... (http://www.britmodeller.com/forums/public/style_emoticons/default/hmmm.gif)

Keep on modeling, my friend, it's coming along nicely!

This is something I have noticed when photographing my models with a digital camera, those things show up, but would not be visible to the naked eye.  Also, I loved putting the details inside the cockpit of my Tamiya Enterprise, but after it was built, I couldn't see anything.  So I didn't bother with the next two builds.  How much of the cab will be seen when it is built?  And will the lights help to see those details?
Title: Re: Crawler redo at 1/72
Post by: RichO on 09/04/2014 01:13 pm
TOM, I think what I will do is build a "decal" on the computer and then glue to the console front. Thanks!

MANFRED,
  I'm not so sure what I will do about the steering wheel. At this scale the steering wheel is only about 2.5mm accross, with spokes inside!  I think I will just draw and paint it into place. I don't have anything that will cut that small. As for the chairs and cosoles, yes I will have to clean up the construction a bit. the photos here are just the rough build and test fit. Sanding and filling will give me a cleaner look and feel. I do realy like the styrene to work with. Even tho this is realy small, it has a much thicker and heavyer feel than the paper and so not as delicate as the paper build. I can handel this much rougher than the very thin paper. So I'm not so afrade to get in there and give a good rough treatment.

RON,
 You are correct! The camera shows things that a person can't really see. Altho I will fill the seams a bit to make the painting go smoother. As for the visible details, the cabs do have a large amount of glass, so looking into them is quite easy, and with the lighting you can see just about everything. Besides, you know me, I will put the details in there even if you can't see them. I know that they are in there!
Title: Re: Crawler redo at 1/72
Post by: roma847 on 09/04/2014 02:21 pm
Hey Rich,

do not be stressed out because of the steering wheel, (http://www.britmodeller.com/forums/public/style_emoticons/default/analintruder.gif) but only two suggestions:

You can make a small plastic disc with Ø 2.5 mm and glue on a short stub of round profile (0.5 mm) and glue this on the console and paint it red like this wheel here.

(http://imagizer.imageshack.us/v2/800x600q90/661/JRIjRt.jpg)
Source: NASA

Or you are making on the same principle a disc of transparent foil, glue a thin wire ring on it and in the middle a tiny bracer, that would probably look even more real, just a thought. (http://scaleworld.forenworld.net/images/smilies/gruebel.gif)

The question is only, from what distance you look at the crawler or into the cabin to ever see this detail. But you say it yourself, you knew then, that there is actually a nearly real steering wheel. But about this claim fortunately decide only you. (http://www.kartonist.de/images/Smile/n060.gif)

Post by: Marge Inovera on 09/04/2014 02:34 pm
The steering wheel is only 2.5 mm, eh ... why not just use a length of copper wire scrounged from wherever and wrap it around a small diameter tube, and use CA to glue it together. Eezy Peezy!

And the cab is looking terrific! The small details you're carving out of styrene are out-stand-ing!

Post by: RichO on 09/16/2014 08:49 pm
Thanks everyone for the steering wheel ideas. I recieved a bunch from other sites also, and I think I came up with a good idea. I used small dia. plasitc tube and install the spokes. The steering wheel and console are so small that these items are hard to see in real life.

Hey All Together,
 
   So I have been absent for a few days from posting. We had blown out the water main to the house, and I just spent three days digging up my driveway and rebuilding the water main. Tree roots had crushed the water line and I had a time of it, watering the neighborhood. Only two days without water in the house tho, so not to bad overall. I'm just to old to be digging trenches and pitts by hand. But whats a guy suposed to do? I saved about $5000. doing the work myself!
 
So over the last four days I have not worked on the build, but this mornning I'm back to work, a bit.
 
  These photos are of the test fitting of the "D" cab. I still have some placement work to do here. The cab is just tacked into place for now. I have to install the cab at this point because there is outside lighting with this, and needs to be wired in at this point.

  Now I get to start work on the "B" cab and get that wired into place.

  Thanks all for looking, be back later!

Thanks All for comments and following along. I have an update for today, so...

So a couple of photos of side 3 finished!  I can't reaiiy go much farther untill I get the second cab completed, so I will now concentrate on building cab "B" for a few days.
Title: Re: Crawler redo at 1/72
Post by: RichO on 10/15/2014 08:04 pm
Hey All,

  These photos are of the building of cab "B", the second cab. The two cabs are identcal for the model, so the build whent smooth and as expected. The update for today is the finishing of the second cab. I didn't take as many photos of this cab build this time tho. I'm not sure why this cab build seemed to take forever to finish. The boys in the fabrication Dept. were having a work slowdown.

Photo #1, In this photo all the rough pieces have been assembled into their respective parts. I found that cutting all the parts out first, for this cab project, was something I don't normaly do. I thought it might speed things up a bit. I found that cutting everything first was a bouring way to go for me. I like the veriety of cutting and building small subassemblies, much more satisfying. My brain works in strange ways.

Photo #2, In this photo you can see the construction of the support strutts for the cab walkway. The white unpainted strutts have a web like pattern to them. The strutts on the floor hold up the walkway screen. The strutts on the walls stiffen for the added weight of the cabs

Photo #3, Here are the parts painted and ready to install.

Photo #4, In this photo is the assembled cab, with walls and roof to attatch. The assembly whet together really fast with all the parts preped first, but I still like my usual way of building.

Photo #5, This is a shot of both cabs together. The new one need painting on the outside and few more little tweeks, then, paint shop boys.

The next thing to do is to wrap up this cab #2. I'll be back with the light test for this cab and the final mounting of the cabs to the crawler.
 
 I'll be back shortly All, thanks for watching.

The exterior lighting is now complete. I will now move on to the "Porch Lights".

  The cabs have a single light each, the Controllers Office has two lights and the porches have four lights and four lights for the trucks. 12 lights for the next part of the lighting chapter.

  To start with, I have a new product that I want to try. I got these from a model railroad site and thought I should give them a try. These are stamped aluminium light shades. I ordered several sizes to play with. I chose the larger size, it seemed to work great for scale of my project.

  This first photo shows the size of the light shades.

  Today I'd like to show you how I sealed up the top and bottom of the crawler.

The first thing of course is to cut out the top plate.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/17/2014 05:19 pm
The next thing I did was to secure a corner, then make sure that all the parts aline. I used a sheet of copy paper as a dry lubricant to keep the new cut part from hanging up on all the wiring.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/17/2014 05:20 pm
Now I simply rolled the top plate and glued as I went along.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/17/2014 05:24 pm
Photo #1, Top plate on and secured.

Photo #2, Top plate painted.

Photo #3, Chassis Top in place. The Chassis Top is removable to show off the inside and for access for more model building. The engines, motors, pumps, ect...
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/17/2014 05:31 pm
So now the bottom plate is mounted the very same way as the top plate.

Photo #1, The bottom plate is cut out and secured to the main frame.

Photo #2, Partial painted.

Photo #3, The bottom all cleaned up.

And your suspect looks too cute to be guilty!

Post by: RichO on 12/18/2014 07:23 pm
RON,

  I still have to finish the wiring chapter and then comes the chapter I'm looking forward to, the walkways and stairs. So the truck assemblies will still be a ways down the road. As far as "Sonny" goes, he always looks innocent, until he feel guilty enough and just confesses.

Hey Altogether,

   Today I will show how I made the support legs for the crawler. The support legs are called JEL Tubes. JEL is Jacking, Equalizing,Leveling. These JEL Tubes can lift the crawler and its load up or down as much as 6 feet.




 
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/19/2014 01:42 am
As you can see in the photo above The JEL Tubes are also covered with a black material that keeps the dirt and grime from getting into the hydraulic cylinders that lift the crawler.
 
In this first photo I have started with the painting.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/19/2014 01:45 am
I found some wood dowels at a local hardware store, cut to length and painted. I have started the assembly process here.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/19/2014 01:47 am
In this photo you can see that I am using a thin black tissue paper to simulate the black material that is present on the original crawler.
Title: Re: Crawler redo at 1/72
Post by: RichO on 12/19/2014 01:49 am
And even tho the tissue paper dose not quite hang the same way as the original material, I think it gives a good impression of the dirt cover.

The four smaller tubes at each corner will be built during the Truck phase of the build. At this time I have no way to support these and they would just flop around until I broke them or they fell off. So that step will come a bit later.
 
As Christmas is approaching I don't have as much time to build, but I will keep posting for a few more days. So....
 
Thanks all for watching, the build continues.

To build the mufflers I simply used a small sheet styrene and rolled into an oval and then glued on an end cap to each end. In this photo I have already made the mufflers and mounts.

Hi Rich,

very nice progress so far. (http://kartonist.de/wbb2/images/smilies/icon_thumb.gif)

But the protective sheaths of the Guide tubes I would improve in your place, because they have not enough fine wrinkles. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/rolleyes.gif)
You could either use finer tissue paper or press top and bottom together more strongly and then unfold again, as the Crawler Guru Mischa Klement (Cyana) had described elsewhere (papermodelers.com). That would certainly look more realistic like here.

(http://www.microartwork.com/Crawler/Images/CornerB08.jpg)

The final result should look like that,

(http://imagizer.imageshack.us/v2/800x600q90/538/TlhWIe.jpg)

that comes close to truth as you can see here:

(http://imagizer.imageshack.us/v2/800x600q90/909/W5lX5i.jpg)

But this is only a suggestion. As you know, the same applies to the JEL Tubes and the Steering Cylinders, which also have such wrinkled protective covers. (http://www.raumfahrer.net/forum/smf/Smileys/yabb/cool.gif)

Manfred,

   Taking a little mentoring from you, I pushed up the "socks" and left them pressed for 24 hours. Then pulled the "socks" down. I had a hard time pulling the retainer ring down without tearing the paper, so this is where things will stay for now. The wrinkles are smaller and fit the scale better. However I did not capture the sagging effect that is in your photo.

Hey All,

 Today I'd like to show how I built the steering arms. As you can see by this drawing, the steering arms and support columns are mounted to the underside of the crawler and attach to the truck assemblies. Their are four steering arms per corner. At this time I will be installing just two per corner. I will install the two inside arms, these are the ones that are on the underside of the corners and attach to the main frame.

I just happen to find some plastic colored pencils that were the exact size I needed for the main steering arm tubes. These pencils have a plastic color covering that worked great for this application.
 
In this photo I have built the support elbows and assembled the arm shafts.

Hey All,

  It's been a while since I have posted here, so I have a ton of photos to show the Crawler build progress.

I'll get started today with the spinning caution lights.

Photo #1, These are the lights to be installed.

Photo #2, Always testing the lights first.

Photo #3, Once the light test goes ok, then I move into mass production.

This photo shows the finish of the first end with the caution lights installed. I have also finished the other end but I did not take photos. I do have a video of the final install of all the caution lights, but can't quite figure out how to show you this here.

All the lights have now been installed and I will now move on to the Cable chapter.

Hey Again All,

  So now I will show the install of the cable trays.

Photo #1, I first cut out my styrene to the shape I need for that location. This is the crawler end tray build.

Photo #2, I used Evergreen angles to build the support mounts on the underside of the trays.

Photo #3, I also used a thin strip that is installed around the perimeter to make the side walls.

Title: Re: Crawler redo at 1/72
Post by: RichO on 01/30/2015 05:56 pm
Photo #7, Once I had all the cable trays built I then started the install of the cables themselves.

Photo #8, I stripped off the outer skin of a bungee cord to get to the rubber bands inside for the cables.

Photo #9, Fit and cut to length.

Title: Re: Crawler redo at 1/72
Post by: RichO on 03/11/2015 05:43 pm
Hey Tom,

  The mesh that I used is the same as the interior and on the fans. I used a 40 mesh stainless, painted gloss black. The uprights on the hand rails is a little tricky. These are Evergreen 1.5 x 1.5 mm angle strip. I then have to place marks on the angle faces and file off 0.5 mm of material. This is the smallest angle strips that Evergreen makes, and the 1mm size is largest I can work with for the size of the uprights that I need. So a bit of compromise to get what I needed. It's really small and time consuming, but all fits well when assembled.

(http://www.britmodeller.com/forums/public/style_emoticons/default/goodjob.gif) very impressive and a clever idea for the walkway construction to hold all parts in right position with magnets. (http://www.britmodeller.com/forums/public/style_emoticons/default/speak_cool.gif)

The crawler has a lot of track shoes. 456 to be exact. For this build I will attempt to build the truck chapter with cast resin shoes. I got a master shoe at Shapeways and now I am attempting to try my very first resin casting.

Photo #1, The shoe master and the mold box.

Photo #2, The rubber poured.

Photo #3, The mold clean from the Lego's.

Photo #4, My very first attempt at resin casting!!

Photo #5, The cast has some issues, but will work for an underside track.

  Now I only have 455 more to cast. Back to the Walkway chapter.

Hey Guys,

  Manfred,  I am only about half way to the number of shoes that I need. I think I will be close to what I need to finish the trucks by the time I get the walkway chapter finished, but even so, I will have some work to do on the trucks before I can even start the build, so plenty of time.  I am starting to fumble around with making a jig to hold the shoes upside down so I can clean up the contact surface. I'll take photos.

  The walkway continues...I did have a little excitement tho. The recent mold I was using was reaching it's end, so I started another mold. I did not make sure about the contact of the clay to the mount surface. I had a blow out!

On the up side...I have a really cool mold of my work bench.

More later!! Thanks

Come on, you can do the other half too. BTW, you did not wanted to use a multiple mold? (http://www.raumfahrer.net/forum/smf/Smileys/yabb/undecided.gif)

Title: Re: Crawler redo at 1/72
Post by: RichO on 05/02/2015 07:52 pm
 Manfred,  When I started to work with the molds, I thought I would make a mold with 5 or 10 copies of the shoes in one mold. This will not work however! It's in the nature of the shape of the shoe. When the mold was made and the master removed, the negative space has six corners where the small air bubbles collect. In order to get the air bubbles out, I have to squeeze, rotate, press, and dig, to get the air out. This would not work with multiple copies in a mold. So to compensate for the multiple shoes, I have multiple molds. And remember that these molds are only about 1/2 inch by 1 inch.

  Just to check in today. The Walkway build goes on, and on... So does the shoe casting. I've discovered that casting while building has cut my walkway time in half, so things are taking a bit longer. All is being completed tho.  I have about 180 shoes left to cast, and one more walkway to build. I'll be back later with photos.

 

Later.

I haven't even visited this forum in almost a year and am amazed at your work on the Crawler.
Simply OUTSTANDING modelling! Thanx for posting! Your attention to detail on the trucks ... WOW!

But seeing the dearth of modelling activity on this forum, can you tell me where else you post your WIP of this. I'd love to follow along.

Thanx
