I finished all the main components of the steering. I just kinda guessed on the lengths of all the lever arms involved. I still need to adjust the tie-rods so the wheel is straight and the turning radius is basically the same in both directions. And I need rubber washers everywhere a bolt head and tie-rod end rub each other. But overall, seems like it should work out fine.
I made some tie-rod ends by welding a nut to the end of an all-thread coupler.
To keep the steering rod centered and smooth rotating I made some inserts for each end out of UHMW
