Have to cut some large bores in relatively thin cross section parts and am considering trepanning them. The issue is that I have never trepanned anything near that size so I don't even know if it is a feasible option at this point. Material is 9" OD 4150 ( 0.6" thick ) that needs to finish at 7-3/4" ID. I was thinking to trepan 7.65"-7.70" and finish with a boring bar.
Reasonable? Or no? Tooling recommendations? Would be doing this on a 15HP turning center with 8-1/4" chuck. Have oversized pie jaws for it already. Set up for 1" sticks and 1.5" ID blocks.
Thanks.
