Some vids of my new bubble column.
I "changed up my mind" as my little girl would say, and I did some things I can now say are improvements on the previous one. The plate drilling was changed, allowing this one to hammer. And hammer it does.
Swapped the 3 way valve for 2 seperate valves. This was more like swapping an auto gearbox for a manual, for want of a better description. I had to drive it, but it gave better control. It also wasnt as restrictive for the pump, so the coolant system had a few flow issues that wern't an issue before. Nothing some better piping and a mop won't fix.
I've made the plumbing on this one a bit more "knock down", but at the same time, 10 mins of soldering and it would be fairly permanant. But no leaks from "commisioning", so I'm happy.
All in all, run went well. Ran some 10% UJ sour mash, 40 litres in 3.25 hours from flame on to flame off, at 93%ABV. Got about 4.5 litres of good drinking stock.
