Is this insane?

Not as likely. Those oversized collets stick out of the spindle and don't really grip that well. A true, properly sized collet doesn't protrude out of the spindle nearly as much.

Ahh I see now, though I think the OP may want to stick with smaller tools that won't kill him as easily

Just livestream it.

Well all be fine I promise.

The end mill has two flats in it. So it would be an interrupted cut. With that much pressure, the show would be good.

Is this the round part with the flange on one end?

If so (either or) is it a fitment issue or are you going for looks?

Yes, I have to slide a rod end in it. The roughing mill really sucked. Maybe I could file the last bit.
But, me profesale machinist.

Exactly, if I had been paying attention, I would have ordered a 3/4" end mill. I probably will go that route after I F$ck this up.

Just an up date on this. It was a success. Took awhile because I only did 15 thou at a time. It came out nice and true. Might be a half thou taper in 2". Put it in the mill and took a couple cuts. Works good.

I have used a similar setup to grind a flywheel. Also to put circlip grooves in axle splines.

.015-.020 would be about right for where you’re at in your armature career.

No grabby, no purple end mill, no missing eyes or extra holes in you noggin.
