Finally, I have the 20mm I need to do the PC, Ended up going to the scrap yard each day, got them, plus a lot more than I wanted.
Scored a 1200 x 1200 sheet of close to 1mm thick copper (havent put the calipers on it yet)
I was wishing that I still had my wood lathe to knock up a tasty former to get all the PC tubes the same, and sticking out of the mixed metal bin was just that, cost me $25 because it still had the motor in it. Let it dry out for a couple of days and just plugged it in expecting a bright flash, fuck me, it works and its complete with tool rest and end stock.
I felt I was having a good day until, on my way back to the yard office with the lathe, I looked in the heavy gauge bin and spotted a rusty, but again complete Hilmor tube bender. Has both mandrel sets for 1/2 & 3/4 tube to boot. $10 for that, thank you very much
The copper sheet, 4m of 20mm tube, wood lathe, and tube bender cost me $145, I was a happy scrapper for sure.
Threw the rusted and seized bender into my electrolytic bath and after 24 hours, it was clean, all bolts came undone easily, and I let it go for another 24 in bits. Prepped and painted it, and just gave it some test bends, awesome piece of kit

I am now doing the same to the tail stock and tool rest for the lathe, while I can now plan a proper jig for curving the PC tubes.
I also wasn't comfortable with using mangled elbows inside the stock for the coolant lines, now I can make them in 1 piece, and bend the tube to suit properly.
So not so much work on the actual still, but more of a gearing and tooling up week
If I could only find a bottle of argon now, I would start tig welding some bits together
