So as I transition from my handy little CM column to a modular design, I’ve decided to build a CCVM head for my new 2”column. I’ve read around the site, and it seems like there have been two materials of choice for the coil:
1/4” copper tubing — it’s always nice to have a bit more copper in my stainless rig, but my missus the artist tells me that copper is surprisingly unforgiving. She says “it’s all soft and pliable. And then it isn't.” I’ve seen some interesting things about avoiding kinks by filling with salt, but…
3/8” CSST - I gather that the corrugation adds some surface area, bit I wonder about the sizing — is 3/8 gonna wind to fit in a 2” tube? It also seems that the only tubing I can find in that size is coated. Is it as easy to skin it as the videos suggest?
So what’s the collective wisdom these days? I reckon they can both be outfitted with pressure fittings adapted to my standard coolant plumbing, so that’s good — I’m a miserable solderer (and a worse welder).
