Do you have dented Western Electric or Northern Electric telephone dial card holder rings. It's a shame to throw these away because there is no longer a source for these rings that is inexpensive. This die works easily to remove all dents.

It's made out of heavily machined steel.

Simply put the ring in one side sit the other side on top.

Tap a few times on a hard surface and NO DENTS. I usually use a small piece of carpet on the steel table or concrete floor but a 2x4 piece of wood will work too. Im only going to sell a limited amount these so if you want a die set buy now.

Pays for itself after straightening out 10 rings.
