Although I do have a few vehicles I need to make control arms for, I'm more trying to get (or be pointed to) a thread going on the choosing of components for control arms. My vehicles that are needing some control arms are a '50 3600 that will have IFS/IRS and an '85 C10 that will need front arms, but like I said, I'm hoping to get a good reference thread going that people can look into and find answers to their questions.
I see you recommended some average sizes of tubing. When do you decide to go up or down from there? Obviously weight will have something to do with it, but I'm also assuming the length of the arm and motion ratio (spring placement) would affect it as well. Do you use any programs to determine feasibility or is it from experience?
I have a Student version of AutoCAD (benefits of being in the military), an engineer friend who can show me how to use it, and a machinist friend to help me build the components.
