Hello all,
Does anybody know the best way to cut a circular recess into one side of a coin? Eg 20mm diameter recess into the back of a 10p. Sort of if you were making a shell to fit a smaller coin on one side but leaving it unchanged and unnoticeable on the other.
Kind regards

You will most likely have to buy a lathe.

CNC machines are very expensive! You can ask Jake Jr. at Airship Magic to machine something FOR you. I have had them make things for me. Ask for a quote from them to make your gaff.
Thanks Steph
WHAT IF you wake up tomorrow with ONLY the things that you THANK GOD for today?

You don't need a CNC machine, just a small Lathe, of course you have to go to learn how to set one up.

Jack_shields, post did not mention anything about if he was going into business.
I had a friend that that wanted to make wood thimbles. He got a small lathe for around a hundred dollars, made some great looking thimbles. The lathe could set on a desk, it was no more then 2 feet long, and 10 inches high. Some books from the library and he was operating it in a few days. Jack only wants to make a coin with a recess circle on one side. He could do that with disc of sandpaper, and a few hours time. The coin can be held against a table with a clamp. By the way Jack, you have to make the recess on the back side of the coin. Otherwise it will do as you mentioned, show through. |
