Ron You're correct. Don't forget, that when I look at e-mail, it's only 7 AM where I live. So my mind just isn't working at full capasity yet.

At A, there are four cents per beat. So a fork that is 6 cents flat is at A442.5. It shouldn't take much to file throat of the fork to reach 440. Wim prime example of minutiae over basics. The math doesn't matter a whit hen you're changing the pitch of a tuning fork, but filing in the right lace does. Unless I'm in the wrong universe, to raise pitch you file he tine tips, not the throat. on N -------------- next part -------------- An HTML attachment was scrubbed...
