Trying to get an opinion of the best adhesive to use in the class for the kids.
Epoxy so far has worked the best, however it takes a glue brush and wastes so much each time, great if gluing up a bunch of pen blanks, but just one is a waste.
CA is great, fast, but have had problems with it. not sticking, actually setting too quickly and students get barrel in half way, CA glue on everything!
Polyurthene. According to the video by Kip (can’t think of last name) Poly glue is best, just takes time to set. Well my students have the time, usually takes a class period to cut, drill, and glue blank. They don’t get to turn it until the next day anyway. I have never used water on poly glue before and have not had problems, however it says to wet the surface. Do you think I should wet the tube or inside of the blank. Poly glue is good solution since it is reasonably priced compared to CA glue, available at any store, and expands to fill gaps if student didn’t clamp tight and blank moves during drilling. However we have had a few blanks not stick, but we are not using water in the mix.
Have tried all 3, gave my experiences. Just wanted to hear others. Probably will hear that CA is the clear cut winner. Hope to hear from some that use poly glue.
