but the wax models sometimes get broken, where the three walls of
the frame meet,
Well, Quatah it’s pretty hard to visualize your model from you
descriptio n… First off,.8mm is awfully thin for any model to
survive the experience. And you probably have weak spots where it’s
breaking, which is why it’s breaking
there~. There’s a way to get
wide rings without damagethat works pretty well, though. #1 problem
with bad molds is bad models, remember that.
Cut your mold and remove your model. Around the rubber that is the
core of your ring cut straight down all around the edge. On the
OUTSIDE of your mold, cut a pear-shaped area that has the core in the
middle of the space. Cut the two of them as neatly as you can until
your cuts meet. That’s hard to describe, probably hard to visualize.
What you are making is a flap on the outside, and when you pull on
the flap the core of the ring will pop out the side of the mold.
Shoot your wax, let it cool, and pull the flap which will remove the
core from the center of the wax. Then open your mold and the ring
will just pop out…
