Not being too keen to start with disaster I opted for a coil+cold finger rather than a dual wound coil.
I cut 3.3m of 1/4", filled it with water and crimped one end. On the other end I put a compression fitting/needle valve, connected it to the compressor @ 150psi then shut the valve and started winding (on a 30mm mandrel). Just quietly I was :D with the outcome.

The question now is, are the coils too close together?
Made a cold finger from some 3/4" and started to weld it up but ran out of Argon :angry-banghead: Going to try soldering it instead now.

So after an afternoon in the shed this is where I'm up to.

Progress may be a bit sporadic as SWMBO has me building a new fence AND redecorating a bedroom for our mid-June arrival.
There has also been talk of the water blasting, a new driveway, ...no wonder I need to build a still!
