How big of a boring bar do you have and how big of one can your machine hold? I've got a beautiful, never yet used solid carbide 5/8" bar and a steel 1" bar that I'd be happy to ship out for you to use. I could have one of these in the USPS Priority Mail tomorrow for you to have probably by Saturday.
Pick one and it can be on it's way in the morning!
That 3/4" one in the middle with the 55º insert has a minimum bore of 1.250" if that one appeals to you. The 1" one (second from bottom) uses a CNMG43x insert and has a 1.260" minimum bore. The 5/8" solid carbide one that uses old TPG221 inserts (just above the 55º one) has a minimum bore of .812".
The bottom one is a 1-1/2" bar that wouldn't fit without a VEERY oversize bore resulting!
Wow! Thanks for the offer Ken and I may take you up on it since I have nothing even close to the size of boring bar I'll need to do this. But let's hold off for now until I get it all figured out. I'm in the planning stages for a future project right now. I think my boring bar holder is sized for a 3/4" shank but I'll have to check to be sure.
Thanks again.
