1.5" double-reducer boka pot/reflux LM

Post by DamYankee »

OK,
I posted last night in "first..." with a few pics. I was pretty stoked with the success I've been having. I thought I'd post more details for those who may find them helpful. First a pic of the rig in Pot still mode so you get a general idea of it.

few new things on the bowl top. I used a standard SS drain, and, as if I was using plumbers putty, I strung a rope of flour dough around and pulled her up tight with the external rings. I used a brass waste connector, primarily for how well it hold mechanically. Now the sink strain has a 1.5" straight thread and the connector has a 1.5 NPT thread. I just knocked down the threads in the connector with a barrel sander on my Dremel tool and it cinched down just fine. the 1.5" copper tube extends all the way down into the bowl area. Yes, I had to grind out the bottom of the strainer for a slip fit. also had to open up the waste connector with the same tool to pass the copper1.62" ve the 1.5 it is designed for. the slip nut with the tapered compression fitting locks it down tight. I had to open up the slip nut and cut the compression ring to fit over the copper.

Next is the business end with the reducers. slightly different twist on the top side. I used a cap and cut it down a bit. I can take it on and off and now I hang my TC on the underside.

ran my limit on Pics so I'll need to follow up this post with a response.

later

Next the coil. Single wound, 8" long. first try thanks to all the input here. the brass water line nipples are the type used in automotive fuel systems. My work has an ample supply of them. great to connect and disconnect with ease.

Ok, here is the liebig. 2 way valve(on left, off both, on right) allows flow thru the small needle valve. center position I can cut everything off if I need to(without changing needle valve setting, and turn to the right I get full flow for stripping. My only project I have planned the next few day is to marry the two outputs through one liebig.

Ok, here is the exploded view of all the hardware. the reflux section is the long one. I get a total of 38" of ss scrubber packed column for spirit runs. All the slip fits don't leak a bit.

I also have a nice "jacket" for insulating the column. It is 1" thick insulation rubber with the ID lined with Aluminum flashing rolled up so it is not directly against the copper.

that it.

DY I would like to say well done! I like the inovation and the craftmanship. I'm also intriqued by Rad's combo still and am currently working on a double R boka in 2 X 1.25"

I hope that you post some operational statistics of your still in the entended mode. Thanks for taking the time to post. O'Mahony
