Lynn Eades,
I agree completely.

I have used a smaller version of the on car balancer, you actually sat on it and pushed it into the wheel to get wheel to spin, then a small sensor triggered the strobe and likewise the datum mark point, however, wheel balance on the majority is in the vertical plane, the shimmy is in the horizontal plane.
Therfore I see that there are two faults, one can compound the other.

If I can isolate the source of the play, I should then just have a wheel balance problem, which I will recognise.

Does anyone know if the spring eye bushes should be bronze or steel in the C15A 1944 model, this has the later steering box and 2 inch leaf springs.
It has bronze bushes in at the moment, both pins and bushes are worn out.
I have been supplied steel bushes which I would need to cut down and ream.

With the rolled steel bush there is a joint, this means I cannot use a straight flute reamer, helical ones are not made anymore for that size, I can have one made.

My thought is to fit bronze bushes back in, ream to the size of the new pins, and shim up to take out the lateral movement.

Once this is done, road test and see what shimmy I have, then balance wheels.

I wish to thank everyone for the comments, all are valued, appreciated and helpfull.

I will post continual, but slow, progress untill the solution is found.
