Had a request for a real wooden nickel. This called for a thing called "two sided machining." Never did it - don't have a clue. I tried my idea of cutting one side, flipping the piece over, and cutting the other. Should work if the x and y are maintained, right? With the lip of the coin everything had to be perfect. It wasn't. After a reach out to Beltramidave and MEBCWD I attempted to do it by the book, using the dowel method. It worked!! I used the nickel bank file and shrunk it down. It's just a 11 x 8 piece of cut off baltic birch 3/4" panel. Finished coin measures about 6 1/4 inches in diameter.
