Another mill arbor.
A lotta work, used 4140 prehardened, and had lots of cutter problems until I drug out the inserts and found the smallest nose radius ones.
Finished item with nut and a cutter and key

On the lathe. You can't see the windrows of chips, some of them haven't been made at the time of the pic. But there are some nice bright blue ones.

Can I order two? both INT 40 taper one at 19mm and one at 22mm.
I can supply material and you can keep the chips http://bbs.homeshopmachinist.net//biggrin.gif

Seriously though nice job. Are the twin keyways for different sized keys depending on cutter?

Nice Job, BTW does that wing nut ever get in the way of anything?

I wondered about that and just how tight you can get it.

Yes, I have cutters (as you can see) with BOTH, and some with only one or the other. And, as long as I had the setup, I decided to cut both so as to keep the options open.

Wingnut is LARGE, about 4" across, so yes it gets tight. That's what the P.O. had on it, and I've never felt the need to change. Better than reaching for yet another size wrench.

It got in the way of the cutter clamp screws, which is why there is a riser under it.

The P.O. had setscrews in holes to clamp cutters.....you can imagine why that was a poor idea from the pic. I rapidly changed over. If I had more square-head setscrews, I'd use them...not all the holes are the same size.

Hmm...apparently I can't type....or proofread......"you sane imagine"?
