Now we will need a way to control the direction of the wheel. This is accomplished by welding a steering arm onto the spindle. This will serve as a lever that will be connected to a tie rod that will be connected to a rack and pinion that will be connected to a steering wheel that will be connected to the arms of the child. In this first photo you can see that a lever and a brace have been welded onto the spindle. I got this design idea from ubuilditplans.com that also sells the plans for a two seater go cart called the S11. I built that project a couple of years ago and I can tell you that their plans are very detailed and accurate. More detail of the spindle with the lever attached. You can't see it very well but there is a 3/8" hole drilled in the end of the lever to connect to the tie rod.

We will need a spindle for both sides and they are exactly the same except that they are not. What I mean is that they are a mirror image of each other. One has to point to the right and the other to the left. You can use either spindle for either side but it makes a difference where you put the steering arm lever. Have I ever welded it on the wrong side? Has an armadillo ever been run over on a Texas roadway?

These spindles are ready for fit up.
