Honestly Bernie I know a lot of people do it a different way, but myself i buy the cheap 1.99 2 pack of regular... not gel!! super glue, and i soak the antler from the membrane side, i put it on and let it soak in from all angles until it is good and saturated, make sure you do it in a very well ventilated area, and with everything else, make sure you wear a mask when grinding antler, bad stuff in your lungs!
