update on Steinway/new questions

[Roger Jolly]

Hi John, 
             Glad to hear you were successful.
The adjacent pin rising is not uncommon, now just think what would have
happened if you had used over size pins. WOW trouble. You would have really
stressed those cracks and fissures. 
Did you heat the epoxy a little after filling the hole? The pin rising is
less prevalent when the epoxy is very watery.

The 6 to 7 mm is a little on the high side for the bottom of the coil.

Regards Roger
