As for reading, I think I've hit the 100 hours mark some time ago... (lastly, I browsed the entire "pot still" forum, stg around 600 threads ?). So, not to sound condescending myself, but please make a point, don't just say "won't work"

.
The choke point between the boiler and the column serves both to prevent mash getting in the column and some reflux. In the same way that some boilers have two parts (cucurbite+chapiteau, don't know the english words). After the choke point, the vapors slow down.
EDIT : Samohon's pot has a 40mm "choke point" before the 54mm column, and it's working.
I'm inclined, after your reactions, to remove the vertical section (between column and condenser).
As for usage :
- brandy (white wines)
- some apple mashes
- UJSSM
- and some neutral to make macerations and herbal liqueurs
Heat : 5500 W propane. (that kind of heater, new from the store, is about 24 euros around here)
Boiler : no idea. I'm visiting local scrap yards next week to get parts and make a 20 gallons boiler.
EDIT : thinking about boiler size, I don't see how it changes the column design : once you get a Q quantity of heat you'll get a V quantity of vapor to treat, wether it's a 20 gal or a 200gal.
I will study the Samohon's pot design
