I got in a 322 with a broken tender step. Here's how I fix broken steps.
That drill I used has a great chuck, it holds the small drills very precisely, but I wouldn't want to go any smaller, it would be a push.:thumbsup:I'm impressed you can drill accurately with that big drill! :dunno: I usually start with a pin vise with a #60 drill bit to accurately position my hole, then I move to the power tools.
The JB-Weld step is my standard, can't argue with that step!
Your pay scale and experience are way beyond mine, lol. I wish I had 1/3 of your expertise.:smilie_daumenpos:I use my Dumore jeweler's drill press for fine work, it'll hold a #80 bit nicely. Even there I like a "starter" hole before I hit it with power. Doing it with a hand drill? Not a chance for me!
