Re: Centripetal-chucking

As a lather, my reaction is that you won't grip tight enough to resist the forces of cutting.

Hi Airy
I was more worried about it grooving the blank at startup and not slacking off enough to feed. However, it's been a quiet morning and I've just about finished it, so it won't be long before I find out if you're right :o)
Here's a pic, not that it looks like much yet, but it gives the scale. I'm just adding the counterbalance.

All done, picture updated, can't try it out because I can't find any 10mm brass and that's the only thing it grips :o(

Does it work?

Absolutely not, it has a grip like a lettuce eating poof with nerve damage. However, I sat down last night and designed in a second fly weight, this one having a 12:1 lever advantage. I will report back when I try that :o)

Hi Mike
That would pre-suppose I knew the required force :o)
OTOH I just faced off a piece of stainless held in it. Okay it slipped when I tried to cut down the length, but I have yet to add the official fly weight and the pukka pivot bolt that will boost the leverage.
I think I am winning, picture updated.
