My opinion, and that's all it is, take it or leave it, the spindle line should intersect as close to centre patch as you can, with the proviso that using big angles to achieve it is not the best way. Part of the reason for not using big angles is that there will be camber change as the steering travel causes rotation around that axis.
Castor, between 6 and 10 degrees, I have tried others and come back to this. 6 degrees gives good turn in less straight line stability, other way round for higher angles. 12 degrees was hands off at full speed for about 1/4 mile, but loads of effort to turn in, and also to hold in the turn, it wanted to fight all the way back to straight line.
Start with a bit of toe in, maybe an 1/8"
Charles, I suggested to you a long time ago posting your excellent drawings on the sticky so that they are easily findable. I still would like to see them there rather than buried in the somewhat difficult search facility. They deserve to be there. That is the "Cyclekart plans and Drawings " thread almost at the top of the Technical forum.
