[HELP] Concentric Turning To A Bore

[TomG]

I use that technique quite a lot Ken and it works well. You are correct though, it does require a close fit on the bore, which is pretty easy with the reamed part as a gauge. I would personally bore and turn that end in the same set-up and then flip and indicate for the other end, but Ed stated that he wanted to use a reamer it so making a stub arbor or pressing a mandrel in the bore would be the best option.
