.....if you don't care for working on a lathe, then, you're not going to like the way I made the looooooong 1/2" drill either...I bought a 1/2" drill with a 3/8" shank - then drilled a 3/8" hole in the center of a piece of 1/2" round stock - again on the lathe, and soldered the drill into the round stock.....instant 24" drill.....
