RPM has a little secret that no one seems to want to tell you; what is the best way to put a hole through your Lexan body without creating fracture points? Use a RPM body post hole punch! Place a piece of wood under the place you have marked for a hole to go, put the hole punch over your mark, then hit the punch with a hammer! Bingo, a perfectly round hole with no fracture points! The punch is heat treated and, when used properly, will last a lifetime!
