Eh Bushy I am that much intrigued about this double boiler I have started on the quest of getting the parts to make one. Now where I thought of cutting the base of a donor keg to get the base of the keg to tig weld upside down just became a lot easier with buying the keg mashtun today. Just cut off the base shroud of the top keg and tig weld it in hole cut in the lower keg. Too eas :music-deathmetal: :music-deathmetal: :music-deathmetal: y...
Now looking thru the thread I did see you used a 6-4" reducer so went and had a look on the 5Star shop to buy one but it was showing no stock :think: so gave Allan a call and he does have 1 left in the workshop. :happy-partydance: :happy-partydance: :happy-partydance: So email sent thru the store to Sue and hopefully I get a reply soon.
I am itching to get onto this project so I can test out that baby brother Lincoln arc/tig welder I had to buy as the big brother went out in fashion throwing 1 metre blue sparks which melted the top of the welder.
So it does look like a heap more annealing needs to be down on the crash cooler or I may just stick on the for sale section and make another one.
Now the difference I will be doing I will be running this using a flame either the crappy bunnings 3 ring burner that won't even work using a hp reg or the one I'm thinking of making basically a few turns of copper pipe with some scarp copper tigged where the burner hole are drilled. Or just go with using an oil burner as I do have a 3 phase industrial fan here working on it's own vfd.
