started putting the frames together, doing 3 at a time certainly saves time in cutting the metal up, not in welding, but it's still a good idea I think. The frame basically aligns itself, so no actual jigs are required, just have to maintain the tight fit of the swingarm bearing tube and steering bearing tube, the rest takes care of itself.

some fun progress, I've finished the remaining bent tube parts for the frame, I had to do some multi angle copes on the engine mount tubes, so I 3d printed some "jigs" to hold the tube down at the right angle and hole saw it on the bridgeport, test fitting with the crankcase proved they work pretty well, using 3d printing to build weldments right off the computer seems to be a good idea, I could probably even see using prints to hold two tubes in position for tacking as well, the possibilities!
