Okay that's it I'm getting a center drill. Have you guys ever gone up in dia. to get to the washer? I mean forget that long skinny drill bit. I never have problems with the punch doing anything other than missing perfect center. I use it against the same anvil I pin on and so the head is pretty solid. Those light scratches come out silverloaf it's just more work to do. I would rather have a sore thumb than more work to do :<0)
Yeah, but guys, the center of the pin must be drilled out. Keep that in mind. Don't trash the collars to get a starting point!
Drill thru the middle!
I have used a bit larger than 1/16 to nab the collars, 5/64. I have found it better to wobble with the 1/16.Quote:

Well, I meant as the 1/16 hole is drilled thru the middle, there is a ring of pin still peened holding the collar on. A slightly larger bit will sometimes cut this out and free the collar. A light touch is needed and sometimes wrecks collars. I prefer to go a bit deep with the 1/16 and wobble it around in order to chew it off, so to speak.Quote:

I need no center punch or starting divot with these as coming up to the bit. They go right where you point them.
I also prefer the shorter, or jobber length bits. Stiffer does better! :D
Also, I have found that a drop of oil on the bit works wonders as well as drilling at low speed, about 250 rpm.' Let the bit do the work' works for me.
I am surprised the pin doesn't spin under the dill. Or, do they usually have a bend in them?
