The Ringy Dingy!
Tonight I built the patented "Ringy Dingy"!
It is a little device for honing your rings to proper thickness, made by turning a little reveal on the end of a cylindrical rod. Wow! What machining genius!
Pop your rings onto the end, and place them on the flat chisel grinding machine and in a few moments you have rings of just the right thickness.
Ok, now I have a batch of rings of 0.030" to crack and then heat treat.
