Re: Bokabo Column Questions
Can't help you with #1, but for #2, yes, you can approximate a potstill with a Bok with the packing removed and the product valve wide open, but your distillate will be very hot. You may or may not want additional product cooling.
#3 Most 2" column on a keg builders use a special flange on the bottom of the still head, and the two are held together with a tri-clover clamp. This guy can tell you what that flange is called (easy flange, maybe) and probably sell you one. smaug@...

> I have decided to make a still based on Bokabob's design. For now it will be attached to a stainless steel pot but I am considering using a used beer keg. In Bokakob's original design he used a one piece 1.5" Dia. column that he attached to a pot via a sink drain with slip joint nut attached to the column. But after reading countless posts on Bokabob columns, I noted that many are opting for a 2" - 2 piece column with a detachable head (8-10" long that contains the condenser and plates) and a second tube for the packing (36 - 48" long). Here are few my questions I have before I jump in and make my column:
> 1. What is the benefit of having a 2 piece column vs a 1 piece column? I suspect that the 2 piece column is so you have the capability to use just the head or head and extra column. Or is it s purely for ease of assembly/dis-assembly? I am in favor of the 1 piece design for simplicity, but if a 2 piece offers more benefits then I will go with that method.
> 2. Could you just run the head with condenser and slant plates on a pot still?
> 3. For those who use a 2" diameter column, how do you connect it to your pot? All my online searches show that a sink drains use a standard 1.5" connector. I have not been able to find a sink drain that uses a 2" pipe. I guess I could use a 1.5" to 2" reducer between the sink drain and the pipe but that seems to be just another connection point that could leak.
