Having a few problems of late in using longer 6" Aircraft 1/8" twist drills for drilling holes deep into long blanks. Most of the time they go in straight. Sometimes as happened today, I was using some Zebra 3/4" blanks and the holes wandered to one side or another and did not stay straight. I'm now attributing this to the drill following the grain pattern but am not sure. I've ruined several long blanks with this happening. Would love to hear a sure fire method of drilling these longer holes using a lathe if anyone would like to comment.
