I’m a little late to the party.
That is a hellofabuild yummy!
Definitely inspiring. I’ve got to start raising my own bar.
Have you made any changes since 6 years ago?
Thanks Stonecutter .
LOL I first started that back in 2013 and didn’t finish it until late 2015 .
I modified the coolant manifold a few times . First I placed a valve in parallel with the needle valve so I could quickly go into full reflux and back to running again .
Heres some pics of when I was using it with a packed section . The boiler shown was just to mount it on . I would use a 80 litre keg on it .
I was having issues regulating flow with the brass needle valve .It was always a super touchy thing .
I was gifted a nice parker needle valve from Copperhead road and decided to upgrade my manifold again .
This time I included a three way valve . I could then have
1) normal plate still with coolant controlled with Needle Valve .
2) No reflux ….. no coolant flow …. IE …Pot still mode .
3) Full reflux …. Coolant bypassing Needle valve .
(Incidentally , you can see three connections to that Deflag . Only two are used . One of them was for an old project and is used as an anchor point to hold the assembly . It is a capped port with a fixing bracket soldered to it .)
This arrangement was extremely flexible and I could switch from normal running to Full reflux iff’n the phone rang . Or quickly switch to Pot mode to strip tails . This meant that the needle valve setting didn’t need so much shagging with to redial in each time .
Although these improvements helped , I was still frustrated at how sluggish the cause and effect of tweaking a needle valve to seeing a change in output was .
I also was frustrated with how the flavour off the spout would change so quickly with changes in wind gusts as I use flame and run outside .
All in all , I was hating the while CM deflag thing . So I decided to modify it to a VM head .
I had a spare module I had made and never used , so I stuck a 1 1/4” nipple on it that would fit the Ball valve and condenser off my 2” LM/VM still . Instead of making a dedicated Reflux Condenser , I just flipped my original flute PC upside down and used the Deflag and inverted PC as an RC .
To this day, I still use it this way . Time poor . One day I’ll make a dedicated VM head for it .
Anyway , I sas blown away by this mod . Adjusting the Ball valve gives changes in output within tens of seconds verses many minutes with the Deflag and needle valve .
Fluctuations in heat although causing changes in output rate do not effect quality if spirit like they did with CM design .
Heres a link to my VM mod

I will never go back to CM
