Thanks for reposting the test, that is a great work. I saw it before and have used some of the glues with some sucess and some failure. In the long run for micarta I use speed bond 324 and 30 min epoxy. The key to both is surface prep and temperature. I sand and clean each side w/220 grit. clean with alcohol (not mineral spirits)and do not touch with your greasy fingers. Apply, very lightly clamp. no more pressure than to hold the two pieces together, like you could apply between your thumb and index finger for 2 hours. Place under a 60w light about 6" away, let set overnight. Make sure the joint doesnt get too hot but near 80f (like on the directions) works fine.
If you need more pressure to fill gaps, resand and start over. Too much pressure will squeeze the glue out and you are left with a weak joint.
