Dan C,

I agree with all the above, but in addition I wll say that I recall 
I've seen some NEW pianos come through with pins protruding through 
the block...  ;-{
(Baldwin??)

I always have a 1/2" piece of plywood between the jack support block 
and the pinblock which allows the pin to go through the block, but 
still doesn't allow the bottom lamination to blow out. I also use 
scrap plywood while drilling the block for the same 
reason.    Another problem with blowout is that you don't know if the 
bottom lamination is the only one damaged.  In PB 2 it looks like the 
removed piece has revealed damage to the second lamination.

Sorry, but I'd say that this block is a do-over.
