Ok, I see how that works now, you're going to build that cap from layers of brass. Wow, that's comlpicated!
I'm thinking you could pin all that soldered stuff together before going to the next layer. Not an easy job for sure. You would need to get some small gauge brass brazing rod to hold the pieces together, especially on the ends and in the middle of the cap. Drill through so the pins are skin tight. You could just leave the ends peened on the inside of the cap, as well as on the outside any place there will be no overlapping layer, then file it flush later. But where layers will cover up any pins, the pins will need to be slightly counter sunk and filed off flush, so they won't hold the next layer up. I hope this makes sense.
I don't think wire or clamps will do the job, since wire gets hot and stretches and gets loose. Clamps will exert pressure in unwanted directions and probably make all your pieces slide around. If you pin it all together, what you see is what you get before it's soldered (unless the pins don't hold
).
You may need to tweak the pin idea somewhat, come up with your own variation that will work best for this project. Maybe even small threaded brass machine screws will work better.
Good luck Mike, I hope this cap works out. I'd like to see the finished project. Bill.
