It isn't impractical at all. In fact if the tooling I have in mind can be made it could be one of the best ways to go as far as production/performance/cost ratio.
I have not done any real work on the design since 2002 so not much to discuss right now.

Have you experimented at all with the opposite of that design ...like a concaved pyramid? I'm not sure how malleable copper is but it seems it would be efficient to stamp once rather than tool over and over for production. Just a thought.
Also ...is delrin a plastic at all or is it more of an alloy? The little I've seen on it isn't very clear. I was thinking in lines of a 3d printer for precision shapes ...the resolution has come way up in the past year.
