Jaras Jig and buttons

[MICHAEL MORVAN]

Gene,
    If I could make a suggestion, key elements in button replacement are 
that:
 1. It is more important that the mortised area of the button be in-line 
(parallel) with the balance hole, not centered in the keystick or button, 
the pin should also be straight, (view the bloopers page of my website 
www.pianoandorgankeys.com where I show capstans, buttons and balance holes 
that are not even close to being centered in the keystick, and this happens 
more than you think)
2. the placement be such that the pin does not hit the back of the mortised 
area in the button when depressed.
Just some things to consider. Mike
