Right now my plan is to bend my own hard lines. I have the tooling to flare them. I have some cheap benders that should work to bend it and I've also designed a nice bender in CAD that I am 3d-printing just as an experiment. I've ordered everything I need from www.discounthydraulichose.com for about $250 except the 1/2" steel tubing. I can't seem to find that anywhere. Anyone got any leads on that they can share?
