jlrii, the biggest problem being faced right now is drilling. Need to drill down 6mm or so with an extremely fine drill bit (that's just 5-6x thicker than a human hair).

You're right, the other option to go with is press-fit, but then it's a matter of finding an appropriate material to use. Stainless Steel is very tempting, but on the whole it's not going to be great in the really long term unless one uses performance sapping water additives. I'd like for the middle plate to be durable, and that pretty much means using some plastic variant unless I can find copper/brass micro-tubes (ala 21 Guage hypodermic needle size).

I do have some Stimpson eyelets, in fact I have the smallest they offer, and they are still too big.

I'll see if I can hunt down some copper micro-tubing...
