I need to make new steering arms for my car as I'm redesigning the steering system. The outer track rod end needs to be at the same level as the control arm ball joint - it needs to be dropped down quite far from its current position.
The arm appears to be forged from what I can tell from the pic below. The hole for the track rod end has a taper - the top is roughly 10.2mm, and the bottom is roughly 11.7mm. Now obviously I don't have the facility to forge a new pair of arms. I neither have the facility to accurately machine a tapered hole.
What I can do though is make a jig and get everything laid out for welding. I'll use the lowest bolt hole on the upright for additional support.
The quick and dirty solution would be to use 15mm or so bar and cut and shut the old tapered hole onto the end of it. But is that going to bite me in the ****?
Any ideas as to the best way to accomplish this job? I'd love to make them out of ali to reduce unsprung weight. Can anyone give me a reason why ali would not be suitable?
