So my NG-1, though to print, is actually just a hair long to make the steering pivot vertical when the nose is locked. 2 deg max and I'm at 4.
Reading up on some other guys that have done so, I created an adjustable end for NG-1. I'll weld it all together next session and that should complete. Looks like I do have enough room in the gear box for the tire with the new position - so at least I don't have to make NG-2 shorter - which is 3.65" (per plan) on the dot.
