you will need to measure the depth of the taper on the ball joint but i think it is about 15mm so you will want about 15mm plate for the top bit. 5mm plate will be fine for the rest.

look at the thickness of the bit on the hub where the bottom ball joint goes for reference on thickness. i would suspect it needs to be about the same.

Very nice work fabrun.

Did you do/can you do beaming and trosional tests on the frame of your model?

In Australia we have to pas Beaming and Torsional tests, the torsional test i sapparently the hared to pass at gretaer than 4,000Nm per degree over the wheelbase.

thanks
jon

hi john welcome to the forum. do all cars on oz have to pass that test? i believe the torsional data should be available as it was done when the chassis was designed as chris and martin got a chap on locost builders to run it through some FEA software.

Hi Guys

Thanks for that.
Yes all owner built cars have to pass beam and torsional testing.
I have read that there was FEA analysis done on the design but i cannot find any results.

thanks
jon

You may find that beam deflection & torsional rigidity testing is down to your engineer,some may require some not.I know here in WA we dont need to do it legally but also we dont need side intrusion panels/bars either.
I would join a car club in your area and talk to members about who they recommend etc as an engineer to use,some are more sympathetic than others.
