Default Diy alignment

I’m in the process of making a diy alignment system so I can adjust toe at home. So far I have 4 square cuts of a plank about 16 inches by 8 for the slip plates. Each piece of plank has a sheet of plastic plywood nailed to it which is used to form concrete decks so some oil will make the surface slippery.

I also have 4 pipe hangers with 4 pieces of threaded rod. Each wheel will have 2 pipe hangers threaded to the front and backside of the wheel making it “square”
This is still all on top of the the slip plate setup.

Now I have a longacre toe gauge which is the 2 pointers and the scale on the aluminum pole. You are supposed to use a scribed line on the tire. But I am probably going to go off the square pipe hanger right up against the pointer.

I’m looking for a way to check thrust angle and to see if my method will work. What do you guys think??

I don't know about the thrust angle thing but I also do my own alignments at home using string method for toe and use a camber gauge for camber adjustments I bought online. I have done 2 alignments after suspension upgrades and my car drives straight down the road.

It's not hard to do alignments at home. U must have right tools and a lot of time on your hands.

Why not support your local alignment guy and save yourself the headache and time? Oh yeah, bragging rights! I mean, maybe if you’re doing them all the time or live in the middle of a forest.

Why? Because most of alignment places don't have a clue what they are doing. Every alignment I even gotten has sucked! My vehicle would pull right or left and do everything but track straight down the road. Started doing my own and dead centered steering wheel and no pull.

It's often the "local alignment guy" who wastes our time and gives us the headache.

More power to the DIYer!

WELL devils advocate here, you could always need to do the alignment just enough to get the car moving forward by any stretch of the term to get it to a shop. im probably gonna need to do that myself soon

Default local guy

If the 'local alignment guy' would align the car like I tell him to, that would be fine.

Usually, though, they'll insist on aligning it to 'manufacturer spec'. The tolerances on those specs are very wide.
