Re: what did you do to your motor bike today?
Mooner is right about the drill speed if you have a variable speed drill press. If yer doing this with a hand drill I will pray for you.
If ya just do like I said, OIL, WOOD backing, START smaller then go bigger, IT WILL WORK, I PROMISE.
P.S. I bet if you look at the back side it has a slight bulge in it. Hence the wood backing for support. It is pushing hot metal and rounding out to the roundness of yer bit.
