FAQ #1
My only other question is I've got a step bit per the specs that Don Ward published and as it turns out it is 17/64 instead of 1/4. Do you think a 64th would make any difference?
Answer #1
Look at the first picture above. You will see some blue painters tape wrapped around the mandrel. That is what I use to take up that 1/64th. The tape does make a difference. I usually use two wraps around the mandrel which is about right for my drill.
