Hi there,
today I have tried to indicate the screw connections of the clamping rings, and it was again a tricky thing with some surprises.

After I had made a winding off from the circumference of the 4 mm pipe with the intervals for the six screw connections, I have cut first 0.7 mm long pieces from an Evergreen Strip 0,25x0,5 mm. And as you can see, this is sometimes not as easy as it looks to produce these particles in a uniform length, but for the first experiments should that be enough.

The next little problem was then the bonding of these parts on the Strip. First, I have with the needle in his left hand touched the parts and have deposed and detained as accurately as possible on the mark. And then I have brushed them with the right hand with MEK, which they sit relatively quickly fixed. And also for this promotion you need a steady hand, so nothing slips.

The gluing of the strip on the Pipe I have tried before, and it is advisable to first to glue only the starting point, which I have used CA, so that the strip is firmly seated.

But because the handling of the needle is such a windy thing, with the next ring I have tested yet another technique with a pointed tweezer, with which you can position the particles somewhat safer and more accurate and also hold better. And then also looked already more evenly.


And for the third ring I have used a 0.3 mm round profile for the screw connections, but the central positioning of the thin round snippets with the tweezer was something trickier and has not become sufficiently uniform.


When I wanted to glue to the first ring after adhesion with CA on the pipe with MEK, there was a surprise, because the ring is broken suddenly, what has surprised me already. This is probably because of the curved under tension ring instantly softens on contact with the MEK brush and immediately breaks because that's then happened again and again.


Therefore, I have glued the next ring with CA,

what has then also worked well and looks fairly decent.



And here you can see now the comparison of the clamping rings on the supports, left the already known type of 0,5 x 0,5 mm strip and the two right from 0,25 x 0,5 mm strips, without and with indicated screw connections.

This was the first attempt, and therefore I want to do no better or worse to, than it is. But that's quite an effort taking a realistic view.

The screw connections one could still carefully slightly round, if they hold, what would surely look even better.
Now I'm curious first of all on your opinion, no matter how it may turn out.
