Can anyone give me insight on how to go about this I have access to a lathe and a milling machine at work.

Access to machines at work without knowing how to use them is a great way to lose a finger. Good luck. I hear that magic dealers sell thumb tips, finger tips, and false fingers. You might need one or more of these.

I know how to use them. I have made collets for a half dollar and english penny using the milling machine and the lathe. The only thing is how does one hold a coin while reducing it's diameter. The collets hold the coin by the sides.

Well, you need a jig that holds the coin by the exact center from both sides being you can't drill out the center of the coin. Ask some of your tool and die buddies at work. They should be able to design a jig for you. Although you may not have all the parts for your lathe, being most of the time companies do not buy what they will not use.
I believe the coin is held with wood connected to metal connectors, for lack of a better word, to the lathe spindles. After you reduce the size of the coin, how are you going to put knurls back in? |

I was going to make myself a few custom copper silvers and maybe a custom copper silver brass. As far as I know none of those require you to put the knurls back in. But that would be something I would try and figure out later on. Thanks for the tip I will talk to the tool and die guys at work.

Make a wax chuck and use it.

Does anyone here on the Café make coin jigs?

Yes I know but I thought you said I would need jigs to reduce the diameter. I have collets witch will hold the coin and allow me to reduce the thickness and hollow out a coin. But they hold the coin by the edges and won't allow me to reduce the diameter.

I do know to use the machines as I made the collets to hold the coins and have made several unexpanded shells but he said to use a jug to hold the coin from both sides while the diameter is reduced and you said to make a wax chuck. I guess I am calling the chucks I made collets. They are metal and hold the coin by a little of the edge allwoing the coin to be hoolowed out and made thinner and are placed in the chuck on the lathe. Are you saying I need to make what I call a collet out of wax and use that to hold the coin from both sides while I reduce the diameter?

I get it I see what a wax chuck is now I googled it and you glue the peice you wish to reduce in diameter to it and then heat it after the coin is reduced to remove the coin. It is like the collets I have made but more of just a post and is adhered to the coin using some sort of adhesive rather than use the edge of the coin to hold it centered in the lathe. Sorry I misunderstood what you meant by wax chuck. The parts we make at work are never as shallow as coin so we can always clamp one side reduse it the clamp the reduce the other side.

Finally! I wondered if you would ever look it up. They are termed wax chucks because sealing wax or shellac was traditionally used as the glue to attach the item being machined. Be sure to leave small grooves in the surface of the wax chuck.

Thanks. I can use the collets I made to make sure the coin is centered on the wax chuck as they are hollow with a recess below the coin diameter cut out and I can make the wax chuck the same size as the the recess and use the hollow part inside diameter as the size for the post on the wax chuck.
