I have one of those vacuum pumps with the Pyrex dome for vacuum
debubblizing. (And another rubbery sheet for casting) that needs a
good home. I used it for over 20 years and it’s still going strong,
albeit ugly. I just got a new one and so no longer need or want this
one (and my wife would LOVE to see it out of her house!) If anyone
wants it for free, write me offlist and we’ll see about hooking you
two up.
