I was in the 'cannot weld' category until I bought a welder and started welding. [
Welding in floor patch panels or a new exhaust run, etc. is great practice. Then you can move on to body panels, chops, and eventually go big time and weld up your own frame.
I'm doing a frame Z and stretch, but I'm not to the point where I trust my welding skills to do frame. So I'm currently cutting all the sections, prepping my frame, and getting everything aligned and tacked together so another guy can come over and do the welding all up in one shot.
Maybe you shouldn't be too picky about what to get this time - think of it as a practice run for next time? So when you do find 'the one' you'll be ready to get at it.
