    Lovely of course there are few bumps on a race track

    Great shot where he has his foot on the spare wheel , I reckon though I will have a bit more bodywork than that style so not possible for me.



    Just for reference if you decide to go that way I took a pic of my Chevy, I thought the box was nearer the shackle it but it doesn't look too far off what you had mocked up with the ply bracket.

    So if you decide on that option it may not be any worse than mine so too bad after all, although your single leaf spring will move much more.

    Thanks for taking the trouble to photograph this , as you say close to what I wanted to do.

    The current steering box is inside the spring pivot at the front , however I can't achieve that if I move it to behind the axle as it would have to be mounted below the chassis and would interfere with the spring , so it would have to be behind the spring shackle if moved to the rear.

    Your description of the Chevy was very comprehensive and gave a great insight into car handling pre WW2 , I certainly want to capture the looks of the 1910's sort of pre-Blower Bentley however I don't 'need' to degrade the Sherpa handling to that extent.

    Although in all honesty the Sherpa is very 1950's in execution despite being designed in the 70's !

    regards Paul

    Also notice the vertical king pins, no self entering at all, so if it bump steers off line they have to manually turn it back and possibly over compensate a little, a recipe for fishtailing.

    Add skinny cross plies on dirt roads into the mix and you really have to wonder at their sanity taking it anywhere near the speeds it was capable of !

    Kapri and others who asked ?

    The steering box has 3 bolts holding it to a 10mm ish plate that has 4 bolts holding it to the chassis.

    So the plate can stay as it is so I don't have to alter the chassis keeping some of my 8 points.






    So if I undo the 3 bolts and rotate the steering box I can weld 3 tabs to the plate and reposition the bolts thus lowering the steering shaft if I need to.

    Thanks for the offer , maybe just need tabs welding to existing one especially as the shape is quite complicated with bosses/spacers on chassis side.

    Need to find one of these :-



    There was one of these on my Sherpa connecting steering box to column.

    I realised if I can find one more it will fit my splines and one end is ideal for inserting a length of tubing into , although they appear to be cast ? which could make welding difficult ?

    regards Paul

    No cast steel is fine cast iron is a pain. Drop me a line when you figure out what you need
