i'm going to use 1/4" pipe going inside a 2" column just wondering what would be the best a double coil or a double coil with 3/4" cold finger or should i just build both ( have plenty of 1/4" to do both ) and test then maybe post my thoughts on both.


sry just realized this should have been in accessories please feel free to move if required

In my original bok i used a single coil of 1/4" about 300mm long. id did the job but i was always worried about vapour escaping - you can stuff the centre with mesh to improve performance. I ran the output through a fan cooled radiator back into a reservoir. Would have to replace water in the reservoir a couple of times during a run

my VM now uses 3/8" with a cold finger. there is a lot less free space & the flow rate is heaps better

I went with the bigger coil cause 1/4" restricts the flow a lot.
