Any advice on building a vapor phase cleaning system?

For a vacuum system I'm building, I've realized that I really need a better cleaning method than 'scrubbing in a tub.' The major problem with hand washing things, is contamination and loss of the fairly expensive solvent. If just used as a liquid, it can only be used once.

Reading up on vapor phase solvent cleaning methods, it seems like it wouldn't be too hard to make one from scratch for fairly low cost. Starting with a stainless steel laundry tub, and adding heating elements around the bottom and a cooling coil around the desired upper limit of the solvent gas. Lots of other details too, like needing two separate sumps; one heated, the other to catch and recycle condensed (and hence clean distilled solvent.) Temperature control and safety limits on the heating sump and cooling coils, facility to run a final distillation cycle and drain-off when done... what else is needed?

I'm not yet certain if water separation would be needed, or how it's done if it is needed.

I'd be using IPA as primary solvent for cleaning. Because it's easily available, not too poisonous, works reasonably well, and is suited to vapor phase cleaning. Possibly other solvents, and mixes as I learn more.

It also occurs to me, that if I build the thing to handle higher temperatures, it could also serve for vapor phase solder reflow work.

Has anyone here ever attempted to build either (or both) such things?
Any advice?

I haven't been able to find any online texts specifically about IPA vapor phase cleaners and their operation, other than that they work, and are commercially available (at costs far beyond my means.)
Anyone know of something useful on that topic?
