Alright, finally got the new head stand done which resulted in 3 bandaids on my fingers. Turns out that copper foil tape is VERY sharp.
This version has only one hole for the grounding pin because the extra holes just created silicone pegs that were hard to trim and just made the wig stick out from the head in an undesirable way. The copper lining is the grounding to create a stronger pull for the fibers.
I was picking up some spray a Gamesworkshop and they happened to have some 3mm flock, so even though that's way shorter than I want myself, I bought it to experiment with while I'm waiting to receive real flock fibers. Also called Don Jer back, because it had been over a week since I emailed them about flock fibers and they hadn't responded. The lady was very nice. She answered a lot of questions and she is sending me some samples of different lengths to try out. Can't wait to get them!
Second try involved seeing how it worked out just trying one medium thick layer of silicone and flocking it right away using the 3mm flock that I picked up. From this, I learned that a thin layer of adhesive is best, because the fibers soak up the adhesive like a sponge and that causes swampy-like areas that mat down the hairs. So another silicone cap is curing tonight and I'll try flocking that with thinned silicone tomorrow. *crosses fingers*
As far as I can tell, the copper lining seemed to have helped. Shorter fibers are easier to work with, longer ones being a totally different animal, but just the way that the fibers acted I'm thinking a combination of the 2 factors made this try work out a bit better in spite of the thick silicone problem.
But here's a look at the 2nd experiment:
