G'day Guy's,
Well with all this talk about double boilers one just has to jump on the bandwagon eh :)) So now got a 50 litre keg with the hole cut out the top and it's former life was a mashtun the new life will be the lower boiler. I do have a donor keg so I'll cut the base off that then get it a snug fit in the hole of the other keg so I can tig weld it together.
Anyway with all this talk about the cool down time once the mash conversion is I decided to make a crash cooler out of 1/2" copper pipe so grabbed a roll and annealed it. I did find just putting a length of 3" pipe in the vice and I used the old cyclinder line off the Ronaldson Tippet engine. Just going short bends I got it down to around 8" and called it a night. Then got thinking if it needs to go thru a 6" hole to be effective better think again. :scared-eek: So annealing when needed got the inner pass down to 3" ID then went on the third coil on the outer part got that dreaded kink :angry-banghead: . So got the multi pliers out and squared up the kink and carried on. No amount of annealing would go right and doing the outer pass was painful to say the least. As I had already wound the coil in one direction I had to reverse it for the outer pass. x_x . Finally got it about 3/4er's done and decided best to leave it and come back later. Well coming back later did the trick and got the full roll wound. So woke up this morning thinking some of those coils are a ordinary and will it go thru a 6" hole :think: Looked around the shed so a suitable 6" guage to use and found an old rusted 6" OD coffee tin :happy-partydance: Just wound some annealed 1/4" around it and easy 6" gauge accomplished. Well that said gauge sailed over it with ease so on went the threaded 1/2" caps using soft solder. Now got it sitting in bath of citric acid to clean up and the test for output is full on so no kinks are stopping the flow. I can run a max of about 17 litres a minute thru it so it should cool the mash in short order. :music-deathmetal:
I hereby thus name this contraption Behemoth :)) :)) :))

Anyway as I do have few weeks to wait for the slow boat from China for that 6" ferrule, cap tri clamp and seal to get here and $79 delivered didn't hurt the wallet. As I have made 2 6-4" copper reducers in the past now got another one to make and I reckon 100mm high should be the go.
On the carter head side I have decided to use my 500mm packed section to have dual life and it's getting a 3" easy flange stuck on the side of it so it can be used for the carter head and by simply putting a blank in to seal it can still work as a packed section. With the easy flange I will tilt up up slightly so any product can drain. I have a new 3" bend so that needs to get some easy flanges so this morning got the first one made.

As I have spend the longweek in the shed and done no jobbies for SWMBO :violence-smack: got told no work no dinner so duly went and did the lawns. :romance-kisscheek: and later this arvo go and get a trailer load of rock from the front paddock for more pavers and rocks for the new wood shed I'm building out og local stone.
Cheers Bryan
