<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Mark, It has bothered me what that 4th method of doing pinblocks is.  I finally remembered having to use the plugging method.  Web Phillips sells half inch diameter plugs that are glued into the old block. I had one block (Emerson grand) that wouldn't come out.  Don't ask to describe.  It can only be described with pictures.  But the answer was to drill out all the pin holes with a half inch bullet bit and plug.  Then I redrilled with the plate in (makes sense since the pinblock wouldn't come out <g>).  Took about as long as a regular pinblock install.

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?     Ray Breakall Piano Technician University of Richmond</blockquote>   Ray 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 Blees U of Alabama [Breakall, Raymond] Wim,Thanks for the reply. You are right about oversize pins. I was really thinking about drilling a new pinblock.  Any ideas. Ray</blockquote> </blockquote> </blockquote> </html>
