Hi list. It has come to my attention that I should seek advice on proper sizing techniques for balance pin holes in keys. I find often that these are too tight (symptom... keys ride up the pins with play making key leveling an impossibility). Yet as known if they get too loose you get checking problems.. noises.. and other un-nice results. I need someone to write out a complete description of the entire hole preperation process. Not just sizing the bottom of the key.. but the whole tomato..grin Newton.. you are great with this kinda thing.. so if you got the time.. or anyone else for that matter. I would be most apreciatofortisimo. -- Richard Brekne Associate PTG, N.P.T.F. Bergen, Norway
