Thread: Help with method of holding disk for turning down outside

If it is a coin you want to face, there may not be enough surface area to get a grip with standard superglue. Maybe epoxy or the gel superglue?

Super glue is very strong.

For a coin I would machine up a recess into the faced end of a slightly larger piece of stock, so that only the very outer edge of the coin face is in contact, and the relief etc is not touching.

Super glue it around that edge face.

Use a TPG to face the coin back to mid thickness. Heat to release.

That way there's very little pressure on the coin and you get a near perfect finish.

On second thoughts, removing epoxy from the face of a coin could be difficult.

Apparently the pukka way to do this is to machine a hollow in one coin, leaving only the outer rim. The other coin is turned and faced to be a press fit into the other coin. That way the join is obscured by the rim. Would require accurate centring though.

Hi Jack,
That is what I am trying to do. My fault as i didn't want to say exactly what I was doing to prevent negative posts that pop up when you do something you shouldn't.

BT I have enough to have a play with now but will keep your contact in mind if I fail to make it work.


Thanks to all for your input.
