Offset vs Bokka

[Ozbrew72]

Hi Again Guys,

Been a while since my first G'day post, been madly reading up on here and HD and even more madly fermenting TPW's, DWWG's and Molasses washes

Great news is that thanks to you guys on here (Particularly the guys on the airstill thread) I've had a couple of amazing outcomes.

1. My Airstill went from seconds away from the bin (thanks to the LHBS turbos) to regular use thanks to the advice and recipes on here.
2. The Minister for War and Finance has gone from "This distilling is a total WOFTAM to "when are you making me some more"
and
3. The above mentioned minister has decided she wants me to build a "proper still" and has authorised the expenditure in the latest budget estimates.
:D :)) :happy-partydance:

So after more time reading all your threads and comments I was planning on building a 2" Boka based on the "easy build" recommendations on here and that we like both neutrals and flavoured's so a detuned Boka for the Rum/Bourbon seemed the go.

Then I saw this:

And given my access to the parts (nice to have an industrial plumber in the family) the Offset seems it would be an easier build (for me)
IF it can be detuned in much the same way the Boka can. It seems to me it should be much of a muchness but I've found there is a shitload of stuff about distilling that seems straightforward but is as bent as a politician's morals.

So my very long winded but rather short question is:

Can the Offset be detuned in the same way the Boka can and produce comparable results?

Cheers and thanks again

Go the Boka .

Shit,you obviously haven't priced 2" Tees. :laughing-rolling:

I nearly went down this path ( unfortunately I had bought the Tees and ended up making a VM)

But If I'd read more first and still wanted to go LM ,then the Boka is the choice

Bokas easy , cut two diagonal slots in a pipe with a hacksaw slip in some flattened pipe that you heated to red hot so its soft and easy to flatten between two pieces of wood ,solder,trim ,file .Done

Apart from the extra cost ,Offset stills have less efficient use of the height of the column because you have to waste space with the valves and reflux pipe.So you have less room for packing and therefore lower AVB alcohol .

Have you looked at VM stills ,bit more easy to operate

go the BOKA ,, i would even suggest going up to 3" if your family member can accomodate :handgestures-thumbupleft: , the larger circumference allows a faster off take

[Ozbrew72]

Thanks for the advice, looks like the Boka it is.

Damn, I can silver solder copper and drill easy enough.
Accurate 30 degree cuts and fabricating slant plates might test me !!!

Oh well, nothing like a challenge !!!


And Yummyrum........ Don't have to worry about the price of 2" tee's.

I know where my brother keeps the keys to his van :twisted: :twisted: :twisted:

GO BIGGER !!! :happy-partydance: nothing like peer pressure ...

[Ozbrew72]

And I'm a sucker for peer pressure!

3" pipe and a few caps should fall out the back of brothers van easily enough.
:handgestures-thumbupleft:
How much faster a we talking?

And does everything upscale? (condensor, take off pipe etc.)

Perhaps i should read some more...... only plans I have are 2"

More research :)) :))

:handgestures-thumbupleft: 3" can handle a faster vapour speed without sacrificing flavour ,,,, bigger is always better in this game. I have a 4" bubbler and its fast on a 2 ring burner ,,, but i know kelby green and brendan have 3" pots and finish a run under 2 hours which includes warm up..... basically with a bigger dimension you can throw more heat at it ,,,, and as long as your condensers can handle it ... it will run BS quick

Howdy,

+1 on up scaling

I started with a 2" boka and after several months use decided the landscape painting I took up as a time filler wasn't working out so changed still.

There are templates on the forum somewhere for the 30 degree cuts ...works ok.
Just in case you change build there a pipe cutting template link in the new distillers section and it works ok...minor last minute hand filling in my case but fairly simple once you've got it in your head and measured up 2 or three times....here a quick off set recently done this way..(just take our reducer cap and reflux condenser... for a bubbler still)

Up sized boka all the way mate :handgestures-thumbupleft: A 3" will be twice as fast as a 2",but 4" is even better still :handgestures-thumbupleft: Just think,if you made a 4" boka and welded a 4" ferrule onto your keg,when you go to make a bubbler,and you will,you won't have to worry about welding a ferrule on the keg,coz its all ready there :handgestures-thumbupleft: :handgestures-thumbupleft:
Just saving you time :handgestures-thumbupleft: :handgestures-thumbupleft:

Geez Guyz!

Go 2" to 3" to 4"

Do you think you're all compensating for something??

:laughing-rolling: :))

So after a bit more reading and research I'm thinking I'll go a 2" Boka to get my eye in and then get a bit more creative with sizing on my next build
Still not that enamoured with the cutting slots and fabricating the plates, I like the idea of the "two cup" or "Rad reducer" Boka still.

I reckon I'll need to convince the brother with some quality product before he starts giving up 4" Tube

[Ozbrew72]

BT1 That is a damn fine looking piece of copper art

Only issue I have with the Boka is that it's a bit..... well........

Boring to look at !!

I like the idea of the "two cup" or "Rad reducer" Boka still.

Lucky he invented that rig before bokakob even found the internet hey, if you ask rad politely he might give you a 1902 hard copy of that design if he can find it on the hard drive that malfunctioned 40 odd years ago that he had rebuilt and cant find :laughing-rolling:

[bt1]

mac

was that a typo 1902 not 2002? :D

bt1

[Cane Toad]

Na no typo,Rad is from the other forum,lays claim that he invented the DR boka :laughing-rolling: :laughing-rolling: :laughing-rolling: 20 years before Bokabob built his,sorta sounds familiar :think: from what Ive read and the way Rad puts himself down on paper,he's a wanker,that sounds familiar too :think: :laughing-rolling:

[Ozbrew72]

Wow !

I just meant the one he built and posted photo's of !!!!

I didn't mean to start an inter forum war

:o :shock: :? :))

Heres my version of a LM/VM Rad reducer version what ever version of a version of a version

viewtopic.php?f=8&t=2950

Its not a boka ,but its got something to look at :handgestures-thumbupleft: and certainly not boring to use .I love being able to see when reflux has started and the mesmerizing dripping and dribbles as the condensate comes off the double wound condenser .WANK WANK WANK :teasing-tease:
