Hi Ben,

How are you going to stop vapour dripping back down the column? Im only asking as I have a reducer boka and wondered if I can take anything from your solution. I made a little hood to go over my vapour outlet.

Well im happy with my results shes a but tall but she goes hard i had never run a boka before and i must admit i was worried on the vinegar run when in full reflux my digi thermo was reading 98 c to 100 c how iam i hoin to cool it down but once i started my sacrifictial spirit run it was clear the will be no such problems with the coolin water on and both elements (3600w) goin and take valve closed the temp on my thermo was 78.1 i collected maybe four liters of 93% and then the temp started to rise up to 81 and abv fell alot easier to use than my lil relfux still thats for sure

i was worried that the condensor coil i made wouldnt do the job but it was great the base of the boka head was hot and the top was cool to touch i did stretch out 3 ss scrubbers to go around the cold finger and my coils to try to create a larger cooling surface area

I also put a small pc on a lil ova a foot long and the temps recorded in my parrot where 23 deg c

Check out this item I found on eBay: http://pages.ebay.com/link/?nav=item.vi ... 04&alt=web


be carefull with th third world country stuff. Yes I go one to. At that price. Put it next a very expensive one and it waeighs heaps more, so whats it actually made of. Is there lead in the stainless mix its cast out off. I then stripped the tap down and the needle was from memory brass, and heavy . Any way I was very sus. So used the 10 times the price parker fluids one from the states and the cheap one for the drain on keg.
theres a reason its cheap.

Possibly the 3rd world valve might have been nickle plated brass.

A magnet will only tell you if its mild steel... Not much good on brass...

I was advised by my supplier they're only a stainless body, everything else is mild steel ;-)

Hows your still running Ben? I think I should take back some thoughts I offered earlier regarding the hood I was using. I thing this narrowed the opening too much and acted like a venturi, actually speeding up vapour significantly... Are you using anything to stop condensate going back down the column?
