Dick (?), Ron & others, Here's a copy of a post I saved from last September from Willem Blees which might be an alternative method. It'll save searching in the archives. :-) Avery >Date: Fri, 13 Sep 1996 18:42:18 -0400 >From: Wimblees@aol.com >Subject: mortised in pin block was Re: 1914 WEBER PINBLOCK >Sender: owner-pianotech@byu.edu > >There are three methods you might try, other than replacing the whole block. > >1.
