Pinblock Separation Repair

[Farrell]

Several folks requested pictures of a pinblock separation repair, so  
here goes. Click on the links below for the pictures. Several show the  
pipe clamps in place. After applying epoxy into the crack as deep as  
you can get it, it seems to help to tighten each clamp and then go back  
and tighten them all again. Tighten all clamps several times - you  
will find that even though they were tight a few minutes ago, you can  
often keep tightening them more and closing the gap more. Keep cleaning  
up squeeze out as you go.
 
Important to remember to only clamp at backposts. If you try to clamp  
on the spacer blocks between backpost you will only manage to bust up  
the back assembly pretty good - DAMHIK (it was a long time ago - and on  
my piano)!
 
In past jobs on larger pianos I was able to bolt, clamp and epoxy all  
at the same time. On this console, I had space problems so I epoxied  
and clamped - let cure for 48 hours - then drilled and through bolted.  
You will see in two of the pictures that the nut for the center bolt  
was right in the middle of several tuning pins - I couldn't get a  
wrench on the nut with the tuning pins in place. So I had to remove  
them to tighten nut. A pretty acorn nut would not fit on the center  
bolt so I just used a plain nut.
 
You'll also note that I had to go in on a bit of an angle on the two  
end bolt holes because of case clearance problems.
 
Other than that, all is fairly self-explanatory I think. Please ask  
away if you have any questions. Piano tuned up real nice and I think it  
has decades of service left in it.
