If you are working on = high end pianos with soft blocks that aren’t terribly old, perhaps = oversize pins work more reliably. I have not had good success with them. I have one = old upright in particular that the whole bass section was really flakey. I = put in several oversize, sand paper shimmed others. It did not last more than a = couple of years. On a severely cracked block you are only stressing the cracks = more in that kind of situation.<o:p></o:p> <![if = !supportEmptyParas]> <![endif]><o:p></o:p> Then I CA’d it. That was 4 years ago and it is still = holding very snug. Instead of stressing the wood further, CA reinforces the cellular = structure, it strengthens the wood. Of course that is educated conjecture.
