Everett vertical pinblock separation

[Brad Smith]

Regarding letting the tension down...
I found a Kimball upright with the plate separating from the back.  I
drilled through the
plate screw holes all the way out the back, and put bolts and nuts to clamp
it all together.  I didn't reduce tension further because the whole thing
was over 100cts flat
to begin with, probably because of the plate separation.  I did it carefully
though, because of ADDING the new tension when tightening it up.    This
isn't really a crack repair requiring adhesive, so I didn't add anything to
the mix, just better 'clamps' than the original lag screws.
