disrupted mortises

[MICHAEL MORVAN]

Chuck,
    Thank you for your kind words. I made the notching jig and most of the 
other jigs I have. The planer was part of a collection of tools and jigs I 
acquired from Frank Stopa of the Connecticut Chapter PTG, it is called an 
ivory "Grail" and is used for planing down and leveling ivory keytops. I 
will be updating my website with more pictures and slideshows soon, I am 
also taking the pictures to complete the keyboard restoration supplies page, 
so come again.  Mike

>>thicker sized cloths or replace the mortise entirely, you have more
>>flexibility for slop in the front rail than the balance. The services page
