Gemini steering arm to pitman arm ratio?
« on: 20 Apr 22, 09:24 pm »
Looking at the Gemini spindles and steering arms, they measure about 105mm from king pin centre to drilled centre for tie rods.
I am in the process of working out the length of the pitman arm between steering column centre and tie rod attachment point and I think it should be 70mm . Anyone come up with vastly different figures
... Or the same ratio and have any comments as to how it works in reality?
... You can lead a horse to water, but a pencil must be lead.

That's not far out at 70mm. I have a feeling I used a 0.75:1 ratio on mine and it works perfect.
If you can drive round corners, you're not going fast enough.

Many thanks Jim, I can drill and weld the plate with a little more confidence now  :)
