Hi Samy,

We' ve supplied a number of builders in Sweden with wishbone kits, ours use 2mm for the lower arms, we also supplied a certificate of conformity listing the material used, standard it conforms to, production batch etc etc, one customer did the calculations and the parts we supplied were satisfactory for the application.

Hope this helps

Kind regards

John

thanks john, i know that the 2mm wishbones are what alot if not most builders in the uk & in sweden have been useing but what can one do when the tester says he´s not sure its ok:confused: thats why i´d like to know what anyone else has used & if anyone knows what the roadsters disign was based on , was it disigned fro 2 or 3mm for the wishbones?
thanks /samy

I know the lower wishbone material myself and Gus used was 25.4 x 3.25 Seamless tube, which I think was what the book said to use.

Cheers

But the book shows the 25mm tube as being 3mm wall thickness in fig. 5.5 on page 58:confused:

Hi

Whilst on the subject of wishbones. Is there any reason that I cant make them from square tube? Reasoning that it is much easier to cut all the angles on square tube rather than all that messing about with round miters which are a real pain.
