Hello Rich, my busy Plastic man,

secretly and quietly he is starting now with the 1:72 crawler, this is a surprise!

Have you printed the parts on sheet? How did you do that and to what thickness is that possible?

Keep on this amazing beast, I stay tuned!

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.
OMG, I finally discovered what's wrong with my brain: On the left side there's nothing right, and on the right side there's nothing left!

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?

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...

LAR,

  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.

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.

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?

Keep up the great job, this will become a monstrously powerful crawler for heavy traffic.

Looks great.  I would suggest motorized treads, but I don't want to give you anymore ideas!

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.

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 ...

I let surprise me and stay tuned.
