balance rail holes

[Richard Brekne]

Simple tool really, and I am really glad Terry brought it too my attention 
on the list a few months back. You are correct in your guesstimation about 
its use. At least thats very much like what I do with it. I use a balance 
pin to allign the jig to the balance pin hole, then lightly tap to make my 
indentations. After that its just to replace the material, however you do 
that, and redrill the balance pin hole. I mark the hole and use a drill 
press myself. I like to also make sure the inside of the key has plenty of 
room for the balance pin for and aft when I've removed the material I am 
going to replace. Its really suprising how many times you run into keys that 
bind on the balance rail pin.

Cheers
