Xylol for tuning pin bushings

[Farrell]

Or, if you want to use bushings, why not just cut a bunch of appropriate 
diameter plugs to length (hey, maybe even cut them out of Delignit), ream 
plate if needed, tap bushings in (maybe a drop of glue on the bottom?) and 
drill them out with the same motion when drilling the pinblock. I've not 
ever done it that way, but I've wondered about it. Any thoughts?

How does Yamaha do theirs - my understanding is that they do it differently 
than most rebuilders - they must do something akin to what I've described.

Interesting.

For that matter, why not just epoxy the entire block to the plate (at least 
on pianos where the block is not mortised into the rim), and epoxy Delignit 
bushings in (to the block and to the plate). That would sure make things 
nice and solid. I thought about that when looking at this Julius Bauer grand 
I was working on a while back while thinking of Ron Over's plate/pinblock 
design - much like the Bauer where the pinblock is surrounded on all sides 
by plate flange. Just epoxy the whole dern thing together. Why not? The next 
guy can simply cut/route/drill everything out 95 years from now.
