I agree with Z this is a Brilliant solution, and one I need to remember.That is an absolutely brilliant solution!! One that will be copied in the future I'm sure. Well done!!
1/2" medical gas tubing, made from anhydrous copper, once you break the seal on a 50' roll, you have 48 hours to use it, or scrap it, because the water vapor in the air starts to degrade it. 1/2" nominal OD, minimum wall thickness of .062, max wall thickness of .065. talk about easy to crush...
but my caliper only needed .001 scale, not .0001 or better.
Echo chamber in here too. Amazing work, next level attention to detail this is.
I know guys who used to pump that stuff full or Argon gas, leaving one end with a pinhole, and then solder the both ends closed with solder, to get more life out of the tubing roll. don't know if that was Kosher. I never got into fixing Medical Grade electronics, as some of the requirements were a bit over done, but then again, a person's life may depend on it, or may not, sometimes I wondered if copper degraded that quickly, then use something that doesn't. Many of the Med Techs I talked too said it was to jack up the prices and service, planned obsolescence. I'm not an engineer, so I don't really know.
My recumbent Trike has a wall thickness of .050" but it's 2" inches on the O.D.. The larger O.D. gives the strength. I knew a guy who made world class hand made racing bicycles out of Chrome Moly tubing is they are only .010" of an inch thick!! Frank Strnad was his name. His passed Set. 2019, an true gentleman. I truly could not say enough good things about him. He was selling his miller Econotig Tig Welder for $1000 bucks, but when he found out I wanted it, he gave it to me for $300 bucks, with wand and foot pedal!! I was shocked. He wanted me to have it. It is so new, he built only 60 bicycle frames one i but needed something that could go lower than .015" of inch thinner. Every bike he made was measured to the person buying it, and made to order. People came from all over the world. His bikes et a pretty penny but you never see them for sale. Of the 2 pics below, the blue one is the last bike he made, and the Carbon Fiber one is one of his also. He used the finest components and laced all his rims. All frames, as I wrote earlier, were built to spec, and you had to come in to be measured on a jig he built.
The primary concern with med gas is a clean environment to start with. I never used argon, but I flushed with purged all my jobs with helium, and vacuumed it off before sealing for final delivery. The way the concern was explained to me by a chemical engineer, is that certain compounds, which can be in normal air, combust spontaneously in the presence of pressurized oxygen. Hydrogen being one, thus anhydrous copper. some pipe sealants contain chemicals which explode in contact with oxygen, some soldering and brazing fluxes contain these as well. I always silver soldered or 25% silver brazed med gas.

Wow, just saw this thread today, your work is exceptional. I will watch your progress with interest. Really amazing work.

That's strange, I only used 253 pages of 160 gm for that Optimus Prime build? (I did not print the instructions but viewed them on my pc).
OPTIMUS PRIME
This is a fantastic card model of Optimus Prime from the Transformer film series. The first part to be made was the head. ...

In this case, I glue the back side with glue so that the wire does not fall inward, since I had to make 0.45 mm holes, due to the fact that it is very difficult to get into the 0.3 mm hole fitted to the diameter of the wire during weaving.Woe this is looking fantastic. Smart move to solder the wires.
WOW! That is brilliant!

In parallel with the panel rebuild, I am assemble the toggle switch covers. I cut the part into 3 pieces and assembled it. This method produced sharper corners of the parts than if I just bend by folding lines.

Experimenting with toggle switches. I decided to use copper wire, with a chrome finish, as it is soft and can be flattened.
That looks very good!!!

The last couple of working weeks have been very hard for me and only today I found time to continue modeling.
All the toggle switch and small details are glued on. The switches are painted in light gray on both sides. Glue and paint every switch is very quickly, but it took a lot of time to cut its.

I agree with mijob, incredible work.
That has turn out AMAZINGLY MIND BLOWING! The detail is so very realistic!
Absolutly Incredible.
