    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.

    I started with the smaller center bit and then chucked a slightly larger one in to weaken the pin a bit since this had 2 collars per side. I figured id see if I could pop the first and maybe second without drilling too much with the 1/16" bit. didn't really prove beneficial in this case, other times I have drilled out minimally like that and popped the collars, then snip the little bit of pin and out she goes. hitting it up with a 3/64" bit on a 1/16" pin would accomplish the same thing, weakens the pin enough to pop the collars without risk of buggering them up.

    The collars must just fall off or stick to the bit. Prying is a destructive method. Once I get a little pin showing the file gets the burrs off so the rest just slides apart. I blew out the backside of a scale once and learned that lesson. No prying.

    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.

    gotcha! I didn't understand what you were saying the first time, now I sees it all clear!

    I have found a link to better describe what I mean by split-tip bits, if some don't know.
    The Difference Between Split-Point Drill Bits & Standard | eHow

    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!

    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?
