Jason...
37* flares in SS -- my one trick pony - 37 degree flare tool with rollers in the cone... $pelled expen$ive tool. The rollers in the flaring cone help with friction etc.
Double flaring SS -- I do with my MasterCool hydraulic flare tool -- and their set of 37* double flare dies.
Yeah -- If I remember ... I'll try to post something up but it's really the same as steel tubing - or aluminum... just better tools. Even then - they're probably overkill but it makes me feel better...
