I have fully welded the frames RS1/2/3 and 4/5/6, I have minimzed distortion by tacking the frames to my bench when welding. The result is 2 flat C shaped frames ready to weld to frame and upright.
I have ground the welds flat so uprights sit flush on top of lower frame and, obviously, under upper frame. I was not happy to put the uprights in place without welding up the frames.
See my blog for picture, more coming soon.
I have not built the transmission tunnel yet but up to now I dont recall having this problem of 'hidden joints' anywhere else on the chassis. Everywhere else I have tacked only and will weld later.
Cheers
Leigh
