Ray,

There are (I believe) 4 methods of boring pinblocks, as described by Jack
Krefting in the PTG reprint kit titled "Pinblocks."
This is great reading!

If you wish, I can forward you a report on 3 of the 4 methods I've used (in
the piano, in the plate and on the bench) and you can draw your own
conclusions. (Darned if I can't remember what the 4th one is!?)

Just e-mail me direct: mailto:Cramer@BrandonU.CA

            Dear list,

            Anyone have a good way to drill pinblocks while in the piano? I
have a
            couple of Steinways where the pinblock is in good shape but
needs oversize
            pins. I have heard about table drill configurations where the
drill can be
            mounted over the pinblock area on a sliding rail. Any ideas?

        I don't know if actually "drilling" the pin block is what you want
to do. You are probably going to use 3/0 or even 4/0 pins. There is no need
make the holes any larger than they are. What you might want to do, however,
is clean the holes. I would suggest you get a .22 caliber rifle bore
cleaner. Just chuck it in a hand held drill and clean out the holes, at a
slow speed.

        Wim,

        Thanks for the reply. You are right about oversize pins. I was
really thinking about drilling a new pinblock.  Any ideas.
