Irwin bit

[Isaac Sadigursky]

Hi,David! Drilling existing hole can be tricky and dangerous. UNIBIT drill
bit works for me, enlarging the hole to 1" in 1 pass.If you prefer to drill
existing hole with Forstner bit or even Irwin-plug the hole.Don't laugh,but
wine bottle cork works as a plug. Call me,on Saturday I will be in S.F.,I
can bring my retro -fitting Kit and we can have a little chat.. Be well..
Isaac

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?
