Hi guys sorry I havn't posted in a while, work an all that. Iam in Ukraine working at the moment and will return home in March (next month).
So I have read your sister site from cover to cover more than once, it did'nt all stay with me,some of it was pretty heavy, but Iam a lot more clued up on it now than I was 2 months ago.
So here is the plan:
The Boiler:
50 ltr SS Keg:
Propane Burner:
The Column:
60" (1500mm) by 2" (54mm) Copper Pipe + Threaded connectors
Stainless Steel Scrubbers
Stainless Steel Sink Trap to connect column to boiler (Thanks Rad)
The Condensers:
1 8" double wrapped Reflux condenser, with external cooling fins.
1 2' (600mm) 3/4" Liebig condenser (with spiral flow, thanks Hookline)
The Still Head:

I have a larger size photo if anyones interested... Just Click Here!
The Logic Behind the Concept: IMHO
The logic behind the concept is simple. The overall height of a normal Reflux head could be kept to a
minimum of 300mm (12"), adding the Bokakob to the mix would only incur an extra 100mm (4"). After some
calculations on condensers on the main HD site, I came to the conclusion that if the column was well
insulated, up and probably to the LM take off and maybe also with the inclusion of a cold finger, then this would
be more than enough to compensate for the extra 4"... Then again I may be completely wrong:
My Research:
I have now got to the stage were I have looked at so many systems, Batch, Continuous, LM CM VM...
I think it comes down to two things, either you go with a well proven system or try to take the best from
maybe two well proven systems with the minimum of extra work needed to bring it to fruition.
A feasability study of the above has been looked at by me, I think it's do-able, at least from the point that
I could build the Bokakob LM at height to include the VM later. Test it when its been built, then add the VM if
all goes well with the results from the LM. On the other hand I could do it the other way round, still keeping
the head at height to add the Boka at a later time after testing of the VM... I think its worth a go... I do not
have a Reflux system at the moment so the choices I have given myself are varied and are open to my friends on HD
to criticise and bend this design in the hope that we will get a hand on this.
Maybe another way to find out if it works would be to just Suck it and See...
Output form the VM would pass through a 3/4" (18mm) OD Liebig. The 1/2" vapour tube would have a twisted copper plate inserted for turbulance. Inside the water shroud I would probably adobt Hooklines copper spiral traveling down the length of the water jacket.
I think this would be a much better cooler for my takeoff than the Graham condenser I had planned.
Thats not to knock the Graham, I just think it would be more practicle when I am doing a stripping run.
I had to buy 3 Meters of 2" copper so I should be able to get a new Pot Still as well..
Well thats the plan, it took a while in getting here but I think this is within my skillbase.
I have read, studied, researched and compared other designs. VM is the way to go, but you just cannot ignore the impact the Boka has had on
some of the members here and on yahoo. Taking the Foreshots, Heads and Tails will be a breeze, leaving the VM for the good stuff.
I will document every part of the build, cutting, soldering, drilling, etc; (did I mention my cousin was a PLUMBER!

As always I bow to the wealth of knowledge and experience on this forum.
I need your 2 cents worth. Would this work? Are we now dealing with Reflux ratios and maths that throw this out the window?
How would this setup perform with a Crossflow Condenser...?
WHAT DO YOU THINK GUYS? Would this work...!
Theres not much to do here in Ukraine in the Evenings, -20 C. Go drinking Gorilka (Ukrainian Vodka)
or sit on this great forum and learn. But I think I will look around for some unusual recipes while I am here.
Dont worry if I find any I will be sure to post them.
Now let's have a look at that Jacko Crossflow....
