Er32 chuck for my 11 inch Logan

And if that is not true, you could be wearing it,

Perfectly true!
STILL looks fine to me!
Heck, I'll look again and see. Yup. Still looks fine to me.
Your opinion may differ. And why not? I'm simply an Engineer. I wouldn't trust me, either. Okay. But it's no more *true*.

A clean, neat machining job done well.

Will be useful and safe within the limits of the ER32 collets.
No one can for see what might happen but it is no more dangerous than many other lathe operations we do regularly.
Safety ultimately lays with the operator.

I figure I can't chuck more than 3/4" and I rarely take more than .025" per pass, so I think I'll be ok. Then again, if I can determine the size and pitch of the existing threads and locate some bolts, changing how it is attached is no big deal.

What I was talking about was the material at the back of the backplate, not the front; make it look more like a normal backplate.
