Can anyone tell me how to attach a coin to a lathe so you can work on its side? I have the chance to do a metal lahte course and would like to experiment with ^work and re-milling edges!

It would be better if you set it up on a mill to work on the coin? What exactly are you intending on doing to the face of the coin?

You can attach the coin to the face of a brass rod and then insert the rod into the chuck and work on it was well?

Let us know what you intend to do the coin and it will help us with your question a bit more!

I've attached it with wax and made some nice shells. A little hard to center, though ...

I was planning to make some shells or re-mill the edges of some worn down coins! I don't know, maybe just play around with some machines to see how things work!

You really don't want to just "play" around with a lathe my friend? You could lose an eye or worse?

Best bet is to go to your nearest machine shop with your coins and let them "Play" with the possiblities?
It doesn't cost as much as you might think? Give it a shot?~r2

To do edge work on a coin you have to hold it "between centers". A flat piece of rod or barstock a little smaller than the coin is held in the headstock (chuck), the coin is placed against this flat surface and then the tailstock is brought to bear against the opposite side of the coin. The coin is held in place by the screw pressure of the tailstock.

Correct centering - using a dial indicator - and solid pressure from the tailstock is necessary to get proper results.

I think you are presuming that I have no or little machine skill-give me some credit"my friend"! Some helpfull advice like Thomas's would have been nice and non condesending.

I am sorry Joe F. I really am! I went back to your original post and read where that you had an opportunity to take a metal lathe course?

I missed that or scanned through it too quickly initially? Please accept my apologies? I never meant to sound condescending? We do not always know the age of the person on the other side?

Best of fortunes!~R2
