EVERY pin was that way. Block was not replaced and a highly respected local rebuilder said the guy has simply swabbed epoxy on the holes, so ruined everything.  He also did some other stupid things……..  Refinished piano, with veneer on lid beginning to come loose, not fixing the problem, of course.   But I digress. The issue is the pins……   What would cause the swabbing of holes with epoxy (pins seem to be original size) cause different response than wicking CA down into the holes?   I may be smart enough that I have some idea, but am caught in a conundrum. Several years ago I knocked out about 3 pin-sleeves out of sever holes on an old piano.  I then filled the holes with epoxy, then redrilled them and those five holes were very nicely tight, turned smoothly, and had none of the cracking/snapping  I experienced today.     I have no real experience for dealing with this, and would appreciate help.<o:p></o:p> Thanks<o:p></o:p> Les bartlett<o:p></o:p> <o:p></o:p> </div> </body> </html>
