Cracks in pin block

[jolly roger]

Hi Mike,
             For the reasons you stated, invisible repair, and number 2,
the CA will wick through the line of least resistance.  Often between the
plate and block.
By having the piano upside down, you have a nice cup, ( the bottom of the
hole) to hold the CA glue in position so it can wick between the pin and
block. Just more effective in getting the CA where you want it.
Well that was my theory. It certainly is more effective.
Regards Roger
