Fabricating radius arms

[Malcolm Parker]

I would stick to the standard Austin radius arms.  Virtually all the VSCC trials cars use them without any obvious problems.  If you make the radius arms very heavy and rigid, the next weak point is the front cross-member.  Where do you stop.  I take the view that if you hit a large rock or tree with a front wheel, it is better to have a bent radius arm than a buckled chassis.  A standard radius arm is relatively simple to straighten.
Austin 7 axle parts are quite light but are made of very good metal and are very strong.
