It was cut down just below the handles, and had the coil unwound and lifted up. Apparently there's a built in thermostat, I didn't see a variac around it. No cooling was used, ran primary bulb into the heating chamber, 2 secondaries and a take off. The w/washer was a 2.5" dia motor 4" long that moved an arm up and down, which then rotated the bulbs.
I thought of several improvements, a teflon bushing in the slot on the urn would be a good idea for turning. A hair dryer or hot air gun would probably be more effective/efficient for heating things up. The pump went through a dry ice trap... "Neccessary for good vaccuum" was the quote...
He had remarked earlier that this was how he got those 5ml quantities of final product to distill to water white oils in the book...
It was quite impressive!
