For a design for a safety enclosure for the caster, look for a metal
spare tire cover for a old conversion van . That is what is what I
have chosen to use on my Vertical platinum casting machine.
Look at one of the catalogs from Rio Grande, Swest, Stuller, …
There are illustrations of vertical casting machines in all of them
. It looks like they are all made by the same manufacturer. I have an
older machine which I need to get running . It is hot and the garage
is not air-conditioned. It is summer in Dallas. I hope to have it
running by the time it cools off.
My machine came used, moderately priced, and without papers.As I get
any more I will share it. The coil springs inside ( 4 in
my machine ) have been replaced and up graded to a degree.This should
increase the acceleration and the ability to throw a flask with a
higher G load .
The machine I have was fitted with a flat end which will hold the
flask and allow a vacuum to be drawn from a vacuum casting machine.
The vacuum hose leads from the bottom to a universal swiveling pipe
joint which can then be attached, via a hose, to a vacuum pump.
I need to know more about these machines. I need to know if the
vacuum attachment is a useable idea. I also need to know more about
the idiosyncrasy of these machines and how to get the most out of
