Time is a real problem right now I have way to many projects going
on but I think I can get the info shortly. the bottom spinning sets
flat to the bottom and if memory is correct there are small notches 3
or 4 to allow the oil under it. I think the oil level is what
generates the pressure difference to force the vapor to the top. I'll
get sketches / photos

Hi Ron,
I would love some dimensions if you have the time.
From what I can see of the glass design it should be simple to
build in
aluminium or stainless.
Do the chimneys actually sit in the oil or do they sit just above
the oil?
Thats the sort of questions I have at the moment.
I would use a freezer coil and jacket surrounding the parts
requiring
cooling to experiment with.

Welcome, the glass pump looks real sharp It looks like a lot of
work
to put it together.
E-bay seems to be where most of us get used stuff.
The workings of most of these pumps seem to be simple so I don't
know
that you would need an engineered design, rather just scale some of
the existing sketches and go from there. I would be glad to measure
up one or both of mine but they are very old and I don't know if
the
design is obsolete. I have a CVC 6"(I think!)and a varian 3" If
you
have access to someone with a wood lathe and metal spinning
experence
it may be easer to make one from some soft (1100 )aluminum and
pipe.
The glass one does looks nice. How do you cool it?

some time ago on the net i saw a site witch talked about plans to
make your own VD pump out of ordinary threaded steel or copper pipes
and fittings and performed quite good especialy from out of standard
plumbing stuff, i cant remember what magazine it was all i know that
it was a monthly science mag like american scientist or amateur
scientist or something like that
