Calculating turning circle

[Davi]

A while back I found an sum for calculating the wheel angles required for a given turning circle, only I've misplaced it. Anyone have a copy?

Easier to just draw it (particularly if you are using CAD).

The instantaneous centre of the turning circle is where a line projected along the rear axle line and a line projected at 90 degrees from the steered wheel intersect.

Don't forget your Ackerman geometry - with full Ackerman the two instantaneous centres for the two front wheels will coincide.

yeah suppose you are right, that would be easier! why do I always see the complicated approach?!
