As a follow up to my original posting, we, er, Norman, husband and
Workshop Wizard, took the vacuum pump apart the next day and soaked
the parts in oil or whatever he did to clean it further. He made a
new gasket, gooped it with the gasket stuff and put it back together.
It is working wonderfully now, chugs along nicely and pulls 30
inches Hg. Some previous clown got the knob on the front of the
caster out of calibration. So today Norman is working on getting it
calibrated. He is my hero. Did I ever tell you he built a Questair
Venture out of aluminum?
Still would like the instructions if anyone has any. Otherwise I
figure it goes like this:
- do burn out as usual
- turn on vacuum caster.
- place flask on caster
- pour molten gold or silver
- wait for button to stop glowing and quench as usual
- turn off caster in there between 4 and 5 after metal has been
Does that basically cover it?
I guess we could burn out an extra flask and use it as a sacrificial
lamb, so to speak, then if it works, go with the vacuum caster. If
not,the spincaster is always set up.
