Really? Cause I just sourced appropriately rated threaded components from the internet and screwed them together with thread sealant from the auto shop. The hardest part was probably modding a minifridge to run on its back so I could fit my receiving tank in it for faster retrieval. The craziest mechanicals are probably inside the appion g5 refrigerant reclaimer and bargain basement vacuum pump I got off ebay. In fact, if I think about it this was probably my first real project as a "maker", my design document was literally a single sheet of graph paper. Since then I've embarked on much more ambitious projects (frame-up electric bicycle, cnc plasma cutter, modular light up dance floor...) and I feel like my skills have probably increased many-fold over where I was at the time. If I were to build another one today I'd probably introduce considerably more complexity (electronically actuated valves with process automation for example, perhaps co2 as a solvent which would require cooling with liquid nitrogen). Shit, at the time I think my toolbag consisted of a screwdriver and an adjustable spanner.
