Following the Incident of the Moving Steering Rack
at the last race (and, indeed, at the race before that too....), I was tasked with replacing the old rubber-and-metal-hoop clamp with a shiny-shiny aluminium one. At the same time, the already-shiny-shiny aluminium block at the other end would be re-engineered so that the hole for the steering rack tube was slightly smaller
than the tube diameter, rather than slightly larger - thus having a clamping effect rather than just sitting there, looking pretty, and doing nothing useful (kind of like Jordan, only pretty).
Turns out, the part that used to be rubber/steel hoop, didn't have any nice right angles to go at. So there was a little more engineering in that bit than I'd anticipated:
And just to make life harder, the bottom of that bit was flat instead of round. Cutting a loaf-shaped hole on the lathe is really difficult:
The edges are relieved to account for the lack of right-angledness on the rack. Aluminium isn't as squashy as rubber, no matter how hard you
The new ali clamps will hold the rack absolutely rigidly on the crossmember, which will hopefully reduce the number of turns required on the wheel before any effect is felt through the tyres...
