Haven't located the exact brass, though I've confirmed that it's train brass. Likely fencing. there are three types of train brass. The brass in Tube number 3, the brass in tube number 4, and the brass that backs the rear hinge box behind the scorpion case. I've included a reference.
My idea about the insta-cast to finish the ring sides for the spinning ring worked like a charm today at lunch. I hot-glued the ring to an aluminum plate. I poured in some insta cast. It set in a couple minutes and at the end of the day, I chucked it into the lathe and cut the two holes to fit loosely around my 6" tube. The entire thing isn't perfectly round but I didn't expect it to and it's close enough.
Final pic is the ring tonight. Still to go: cutting the detents for the cages at the four spacer pieces (I'm not going all the way through- I only need registration). Priming the thing with some plasti-kote. Sanding and filling until it's ready for casting.
I sculpted a mummified frog from Super Sculpey, we'll see how it primes. Pix soon.
