after hours of tedious jigging, we welded her up, and I have a frame. :)
it is worth noting that even when all of the mating surfaces are machined, and both frame rails having the same length (within .020" over 124"), it is still a pretty intense chore getting it all square and parallel and level. it took us 3 or 4 hours to feel comfortable about putting the TIG to it. the final frame measures 126.75" on both long diagonal measurements, and both uprights are within about .3 of a degree of being perfectly verticle. also, from front to rear no matter where you lay a level across the frame (rear crossmember, front cross member, or any point across the frame) it is literally dead on level when the frame is on a level surface. thankfully, all the time jigging and machining payed off. Now it's time to start mounting the rear and and front axle.... if that metal would just hurry up and get here!!!!
