Deep Hole drilling
This might sound stupid, but I've been wondering, is it possible to use a gun drill on a drill press? Does a drill press accept gun drills? If not, is it possible to modify the drill press so that it accepts gun drills? How?
I've used normal drill bits to make "deep"(about 4 inches) holes in metal before, but it was very, very difficult to get it straight, and the metal became hot as heck after a while, sometimes the drill bit even got stuck in the metal and it was extremely difficult to get it out.
