A new anti-roll bar.

In preparation for the TDC Ireland 2011 Trail I noticed the front anti-roll bar was broken. The broken bar was a bar I had made from another cars anti-roll bar (ARB), I simply machined a hex onto the ends to allow the Rover to grip the bar as per the P6’s standard ARB. However when I machined the bar I had put a sharp corner from the transition from the hex to original large diameter, this is a no no for a component subjected to high strains, as the part will soon fail due to fatigue concentration.

Machining the ARB

So I pulled out the ‘spare’ original ARB and machined a hex with a good radius leading into the hex. You can clearly see the large nut bored to hold the ARB as a jig for to allow the hex to be formed.
