While this setup is probably ideal for building aircraft, it is
a bit under powered for jewelry investing and casting. A vein
type auto air conditioner pump with a 1/2 hp motor should
evacuate a bell jar in less than 30 seconds. The one I built took
about 15 seconds to evacuate an oversized bell jar. A
refrigeration pump will take quite a bit longer, and wont have
the sufficient cfm air volume for casting anything but the very
smallest flask.
