Locating Tuning Pin Holes

[Richard Brekne]

I have always taken some thin translucent baking paper and cut out to 
match the pinblock face whilst the old bloc was still in, and traced out 
the holes. Then when the new one is installed tape it into place and 
with a small punch mark the center of each hole.

There was an article about this somewhere in a past journal I seem to 
remember,.... something about a way of doing this from scratch with no 
template or diagram to go on. Anybody remember that ?

Cheers
