Cooling Saddle

Hi
Currently i'm using a coiled piece of 10 mm copper pipe around the cask wrapped in foilised bubble wrap attached to a shelf chiller to keep the ale cool it works but getting the coil on and off is a :twisted: :x
i want to make one of these https://www.dropbox.com/s/mdli4pjl4t2j8sy/sml_upcaskcooler.jpg?dl=0 to make the job easier
The way i was thinking of making it was getting a piece of 1/2" ply and cutting the shape i need (in 2d) and screwing it to another piece of ply and using this as a former bending the 10mm copper pipe around it then it can be gently wrapped around a cask or keg to suit
i thought of using a pipe bender but it would be difficult to make the bends and secondly keeping them uniform to keep the finished item pleasing to the eyes and so i can make multiples of them (just had a thought that if i made multiples i could make a pair to go round the fermenter to chill the ale and help the yeast sediment before casking without disturbing the ones around the currently tapped/dispencing)

Any budding manufacturing engineers out there that can come up with easy and consistant ways to make this please post it here

8mm copper pipe is a lot easier to bend to the kind of radius you'd be looking at for that. If you heat it before gently bending it 'round a suitable former you shouldn't have any issues with it kinking :)

You can pack the pipe with sand or salt to help prevent kinking, although I've never resorted to that, and I hear it can be a right sod to get the blasted stuff out afterwards....

I guess if you use salt you can wash it out? It will still probably take a while!

I was chatting with a plumber mate at the weekend about 8mm microbore copper pipe. He assures me that I shouldn't need to fill it with salt as the wall thickness is pretty good. He did also say that tighter bends should be made with a bender though. Good luck!

thanks for the replys
keep them comming
i think i might struggle with the tightness and the quantity of the bends using a pipe bender
i will go to screwfix on friday and pick one up and have a bit of a experiment with a small lenght of 10mm even if i dont use the pipe bender for this project i am sure it will be usefull elsewhere perhaps bending brake pipes for the car

How about using plastic tubing and John-Guest fittings? You could cable-tie them inside a sleeping bag and get some good insulation happening. Just look at the commercial examples for inspiration. You would just then use an ice bath and solar pump to recirc the water round the cask.

Hi HTH
i have a shelf cooler with recirc pump so that side of it is sorted
i decided not to use plastic pipe as the thermal transfre would be less (the casks i use are 9 gallon plastic ones)
so thats already a limiting factor with heat transfre i don't want to make it any worse
but the idea of using pre made bends and soldering them have crossed my mind
i will try making the bend with a short lenght first see how easy it is and how tight radius i can acheve

steve

i will post pictures when i have done something

the pipe bender is on order

Those cooling jackets you can buy for casks use plastic tubing and they work a treat - if you have something wrapped around the coils and the cask it will keep the cold in. If you have a maxi chiller as well then you’re sorted.

After wasting a lenght of 10mm copper pipe this weekend i have now decided to go plan "B"
Using end feed solder on pre made bends this will not look as nice as plan "A" but it will work
