I'll be restringing a 1977 Yamaha C3 in the foreseeable future that has had the tuning pin field flooded with some kind of pin tightening solution.  The paint in the pin field area has been compromised.  I'll be wanting to replace the tuning pin bushings when I deal with this.  I believe the diameter of the bushings to be 13/32", but I don't know the height.  I have lots of the 7/16" height in the cupboard, which suggests they were probably too large for the two Yamahas I restrung some years ago.  The other sizes available from Schaff are 1/4" and 5/16".  Can any of you advise me on the thickness of the plate webbing on this piano?  I could just order both, but I'll try asking here first.

I'm perplexed. 

Why is there no discussion regarding the merits of undertaking a restringing on a piano that has been subject to the described conditions?

And then there's Don's shimming advice.  I feel like it was himself that challenged the physical dynamics of stress on pinblocks using hard tuningpin bushings.  The direction of force on the block is toward the stretcher, being pivoted by the bushings in the pin field.  In theory, the precise fitting to the flange is irrelevant.  Don, did I miss something back then?

What does everyone use for shimming material? Clarinet reeds and epoxy work well, but the reeds are rather pricey.
