Removing unwanted silicone
Posted by: "Tom Banwell" TomBanwell@lumicast.com mentalblow

We finished casting a job with a urethane part with fine engraving. We had
to recast one due to a problem, and when we did the last mold broke down,
leaving bits of silicone rubber in much of the engraving. My question is:
How can I remove this rubber easily. Picking it out isn't working, so I'm
thinking of soaking the part in either kerosene or acetone. I think both
will soften the rubber. I know that the acetone will start dissolving the
urethane if left in very long. Any suggestions? Thanks,
Tom

Tom;
in light of how volitile the acetone is, try some isopropyl alcohol and a
SOFT bristled nylon brush. You might next try wood alcohol (actually
Methanol) sometimes called denatured alcohol. It's worth a shot.
You don't necessarily need to dissolve the RTV at all; simply force it to
"let go" of it's host, in this case your casting!

I think it is important to know the difference between a rotocaster and a spincaster, as these two terms seem to have been used interchangeably lately. A spincaster rotates very quickly in one plane. A rotocaster turns very slowly in two planes. The spincaster makes solid parts, while the rotocaster makes hollow parts.
