5c collet or 3 or 4 jaw it doesn't matter kinda stumps me
Appreciate your reply, its .812 diameter sticking out 1.750, if I take a spring cut it doesn't really take and more material
Holding the work in the chuck only, or between centers?

Tell me, how in the hell can you bore a hole between centers?
Trade secret? Or simply not well-known?
But I happen to have a lathe as can DO exactly that and easily so.
Rack operated, not screw, "capstan" tailstock ram. Hollow. Like a milling-machine's spindle. Has tapers fore AND aft as can mount a sort of "gun drill" rig inherently.
Open center roller-bearing at the pointy-end, tube/"pipe" profile ELSE inverted cone to pick up on the work - depending on whether starting with tubular or solid - does the rest.
Clever guy, Henri Rene Bruet.
And how common are these, how many members on this forum
has one of these ?
Thermite, show us a picture of yours, I’m curious.
Recently I adjusted raper out of my Nardini headstock.
What I meant by running in reverse is cutting on the backside of the part, o.d. or i.d. the material is 12l14 so it's pretty soft
Running between centers means the work is held between centers, one in the headstock and one in the tailstock. Bsic terminology!
