Re^9: more guide rings

  These are something Lee might add to the tool set.  Material is not  very critical ( just stiff and springy) and they are plain  butt rings with about  a 1/8" gap   when inserted in the cup. They are a little oversize on the ID and OD  so they are a spring fit.

On measuring the test rings that seemed about "right"  I found they  all range about midway between 0.025 " and 0.030 " over size on the diameters. With a bout a 1/8" gap when inserted in the cup they just hang on the punch and the cup just  hangs on the ring.  If you have a lathe they are quick and easy to make -- no magic involved.
