How I Make Specialized Folding Coins
Copyright 2006 by James P. Riser
In the example shown below, I am making a folding silver
dollar to go with a specialized type of coin wand. I like to make
the cut for the slot for the tiny rubber bands using my jewelers
Shown mounted in
the lathe spindle is a wax chuck. The coin will be attached to
this with super glue or shellac.
Below are three views of the mounted and centered coin.
The coin is removed from the wax chuck with gentle
Rather than using
a graver to cut the slot, I often use my jewelers piercing saw.
Here is shown the slot being cut. The lathe is running
in reverse for this operation or the blade is reverse mounted.
The completed slot
looks like this.
The next operation is to cut the coin into thirds.
Some specialized coins are not cut into thirds.
The coin is carefully
measured and marked. It is placed onto a "V" notched
board for cutting.
The cutting in
progress. I lube the blade as I cut.
I prefer to add very slight waves to the cuts in the
coin to help hold the coin in alignment when fully opened. For
some applications, a profile cut is made. Such a cut will not
work on this projuct as the coin must take up minimum space when
The cuts are barely
visible on the completed coins.
Two small rubber
bands have been installed and the coin is shown being folded.
Notice how the coin hinges back on itself without over
stretching the double rubber bands.
