Well, I did a trial run with saran wrap. Got the 1.4 micron mylar today, no antistatic yet, that will come next week, but experimented for now just with saran wrap.
I stretched the saran with tape, put one half of the mylar spacer under, pressed it with my finger and no glue. I then placed the other half of the spacer over the bottom one, pressed both spacers together with saran in between, then cut around it with a sharp scalpel.
Surprisingly, this produced a tense, stable configuration without glue. I pinged it with my finger, and it produced a note nearly identical to the Stax mylar membrane. I placed the mylar back into the headphone shell, it all fit perfectly that way.
My thought is to tension the 1.4 mylar, put the antistatic on it, let that act as glue, let it dry with pressure overnight with both spacers together, cut with scalpel, reassemble the headseat, and try it out and see how it does.
If that doesn't work, I will strip out the mylar and try it with glue. I think this system is intended to work without glue, I couldn't find any trace at all of glue, but maybe they use some kind of ultra thin adhesive that doesn't show very well.
