I agree with everything that's been said about drill bits. I have gotten some good ones, that were sharp, drilled straight, and drilled smoothly from Berea and Bear Tooth Woods. I have settled on Barrel Bond 2 part epoxy for my pens, wood and acrylic. Woodcraft sells it. It's two tubes (like toothpaste) and seems to be easier to consistently get equal parts of hardener and resin than the liquid types. It also expands as it dries and fills any scratches, worm holes, or rough spots you have between the tube and blank. I haven't lost a blank since I started using it, other than the ones I ham handed while trying to get that last hair's breadth shaving off my bit. It's a bear to get the residue of the blank off the tube then. Steve
