Hi Marty,
Im interested in your setup, as i want to do a similar thing with eucalypt trees.
I would imagine the hardest part to find would be the main vessel, yours looks like a ground glass top, which would be nice if you could find one (that doesnt cost thousands).
I'm probably going to make mine out of copper, i think this would work for the column and condenser as well, with a bit of work, soldering and cutting.
