As I said in the project list, I have been driving for the last several months on an “eyeballed” alignment. The car drove well, tracked straight and seemed fine. But still, it really needed to be done correctly and today I finally did it.
Aligning the steering is simply a matter of measuring and comparing the distance between rear of the front tire and the front of the front tire. The trick is that you can’t use a measuring tape since the body of the car gets in the way. So how do you make that measurement? You make a trammel bar.
There are a million ways to build one, so start with assessing what you have around the garage. In my case I had a nice long piece of 2×4, so I decided to use that as the base.
A trip to the local Ace yielded a 3 foot piece of 3/4″ PVC electrical conduit and horseshoe conduit mounts.
The 2×4 is about six feet long, so if I want to do a wider car I have plenty of adjustment room. The pointers are made of 0.063″ thick aluminum sheet riveted to 3/4″ PVC electrical conduit. The conduit is held to the plank using plastic horseshoes design expressly to hold conduit.
Here are the details:
