Irwin bit

[efarmer]

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.

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?
