Criterion boring head in a mill, happens to be a Deckel FP1. Boring 2” diameter through hole 4” long. Complication is that the first half inch is 2”, then the bore expands to 2.030” for 3”, then the last half inch is back at 2”. So how to do this. How do I extend the boring bar while I’m in the bore? I think a boring and facing head might do this, but I don’t have one of those.
