wasted CA on grand pinblock

[David Nereson]

    I  CA'd a grand pinblock yesterday, and it did tighten up
the pins, but I don't think all that much CA got down the tuning
pin holes.  There was a gap between the bottom of the plate and
the top of the block, and the top surface was downhill toward
the belly rail, so a good deal of my CA ran toward the back edge
of the pinblock and dripped down onto the newspapers I had on
the keybed.  What a waste!  The stuff ain't cheap.
    But how could I have known in advance that the top of the
pinblock wasn't level?  The top of the plate surrounding the
tuning pins seemed level.  If I had known, I would've jacked up
the rear leg a bit.  But how far?  If the plate above the
pinblock isn't precisely a uniform thickness, you can't be sure.
    Now I'm reluctant to CA again if there appears to be a
noticeable gap between the plate and block (I suppose there's
always some), for fear the CA will just run all over the top of
the pinblock and not get down the holes.
