In woodworking one would/could, if you wanted to use that bit, glue a dowel in the hole to give it wood to bite into and to make centering possible. Otherwise if there is a hole it is only good for knowing where the center of the bit is, which can help somewhat in starting the bit, but isn't as nice as the wood in the center. Edward Farmer _____ From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of David Ilvedson Sent: Monday, October 16, 2006 3:15 PM To: pianotech at ptg.org; caut at ptg.org Subject: Irwin bit List, I usually use a forstner bit for retro-fitting pitmans in Steinways and other grands. Problem is starting the forstner bit into the keybed. I came across an Irwin 1&1/8" forstner type bit except with a threaded starter tip, about 3/4" long. As I think about it now I suppose the starter tip wouldn't be of much help since it is going into the pitman hole...anyone used this bit for this repair?
