Chickering Quarter Grand Pinblock

[Nick Gravagne]

Hello All,

 

I have found myself knee-deep (and delightfully so) in an authentic
Chickering Quarter grand rebuild (belly job only).  

 

Questions: most of us know about the machine-screwed, two-step pinblock fit
to the two-step plate flange (ouch). I understand per my fellow tech and
friend, Les Conover of Albuquerque, how to fit the new block using a
straight ¾” router bit and a router table set up. Any other (aka simpler?)
ideas out there?

 

Also, I would like to replace the agraffes, but the original threaded studs
are slightly smaller in diameter than the standard size available today. Has
anyone re-bored and re-tapped the holes to accept a standard ¼” stud?  Or
might it be better to remove and recondition the existing agraffes?

 

Progress thus far: the crowned soundboard is made and fitted to the case;
the bridges are underway; and it is now time to begin thinking seriously
about the block.

 

Thanks for your consideration.

 

 

 

Nick Gravagne, RPT
