wasted CA on grand pinblock

As an addendum, Dave, how is it you know there is a gap between the block and the plate??  Without taking them apart, it would seem hard to tell.  Are you assuming that since CA leaked out one side that there is a gap?  If so, I'd caution against that assumption, and echo what both I and Dean wrote regarding quantity of CA and rate of application (little bit at a time).

Food for thought.

        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.
