That is what I was looking for.At what point? We don't know where in your build you are and you have provided no reference.
If you mean are the king-pin angles "pointing at contact patch" and caster-angle (self-centering) done in the same operation (e.g. welding the headset-tubes into the cross-beam, then YES; done at the same time.
There is no specific "camber adjustment, each wheel should be perpendicular (and no other colour).
Toe-in/out is set on the length of the tie-bar between the two wheels.
No worries Ron. I also used Popshot's approach to welding my axle mounting tabs bottom of the kingpins with a threaded M16 rod to keep the wheels vertical (I was using SA 90mm drum-hubs for my front wheels).That is what I was looking for.
I wasn’t sure I was missing something, caster & center line angles are set at the same time with basically the fish mouth you would cut & grind in the ends of the cross Beam.
Thanks for your answer
