Joe, Thanks for your experience, and your encouragement. I'm going to try it if the customer decides to go ahead. I'm curious why the long drill bit. I figure 3/8 depth of hole plus about 1" of exposed pin, a standard jobber's bit should be long enough?? Keith, I suppose this is just personal preference, but I'd rather drill 228 holes than flip a 6' 6" grand that's sitting on a stage truck. Thanks for the reminder about turning the pin - I have done that in the past, and it did seem to help, although it doesn't help tuning stability!! Dean, if this project flies you'll get your report!
