Don't know what the turning circle will be yet for certain but I have an average full lock steering angle of 270 either side of straight ahead.
Putting this into a formula of half track plus wheelbase/sin. average steering angle gives me about 4.4M or 14.5 ft radius

... You can lead a horse to water, but a pencil must be lead.

I was a bit worried that mine would be enormous but it is about the same as yours at roughly 15 feet radius.

Hi Jim.
Don't forget that the inside wheel needs to have much more lock than the outside one when turning. (See Ackerman angles in the guide to building a cyclekart at the front).

Thanks Adrian, I have the Ackerman built in in the Gemini standard steering arms and it looks right for the rear wheel, The average either side of center is 270
... Although I hope this doesn't prod the denouncers of Ackerman too much, it's just what came from Gemini  :)

I think the Ackerman angles on the Gemini axles are pretty well correct. I don't suppose any small differences make much difference to a cycleKart anyway.
All looking very good.
