- Can't find it anymore. This is an old idea anyway. Let me describe it
As an example we'll take four 2" columns and put them together so
they form a bundle/bunch (each column touching each other to even out
heat differences). Then we'll make a chamber on top of those columns
and have a VM outlet from that chamber. On top of the chamber
(actually the roof of that chamber) is a shotgun condenser. In that
condenser we can group the pipes so that each column has the same
number of pipes on top of them. The effect is roughly the same as
having a 4" VM column with shotgun condenser.

Might I just add a minor note to your very useful notes on dividing
I, too, was intersted in seeing the flow of reflux. I found glass
tube exceptionally easy to work with and under heat could bend 1/4"
tube just about wherever I wanted it - a darned sight easier than
However, at that stage I didn't have proper needle valves, and I
would say, that though one can see the signs of flow, they are not
great. Narrower glass tube would concentrate matters, though I would
keep to the accuracy of needle valve control.
The joins to the copper tube were made from ordinary poly tube and
butt-ended, so the absolute minimum of poly was exposed.
