toe in tool

I found toe plates much easier to use, and accurate too when compared with a rod-type tool. You can see an example on how to use them as well as make your own for next to nothing in the following link. Oh, and I use two old slightly different Stanley tape measures that are virtually exactly equal in measurements. The important thing is to keep equal tension when measuring.

With toe plates, you are using two separate measuring points, front and rear , while stationary. The accuracy of the toe measurement is wholly dependent on the condition of the wheels/tires. Any imperfection/bulge in the sidewall of the tire or bend/runout of the wheel will directly affect the results. The principle by which the Duby or spring gauge works is simple and repeatably accurate, while being unaffected by the condition of the wheels/tires. They are used only as a conveyance to move the gauge through the rotation of the hubs on their spindles and bearings from front to rear.

Have been reading the post and trying to educate myself on toe in alignment. Thinking about the last car that I had aligned, the device on the wheels were at the center of the spindle. Considering the bar and the plates described, they appear to be below the spindle centerline, that being the case and considering the castor and camber angles associated with the front axle, will the devices actually produce the correct measurement?

Yes, they will. Here’s a link that will be helpful.

The toe plates only touch the wheel so "Any imperfection/bulge in the sidewall of the tire" does not effect the use of the tool.

A bent wheel is going to effect the way the car handles no matter what method you use.

A lot of Model A wheels have some degree of runout, but are still very useable. Some of the plates in the links above have adjustable contact points to measure at the rim, although the plate pictured in post #38 seems to have no contacts points and is resting against the tire sidewall. The point is that any wheel runout can affect the accuracy of toe plates, even if they only touch the rim. This is not a factor when using a Duby spring gauge.

The toe plate can not be used on a Model A as pictured in post #38, it will be resting on the spokes.
 
Back to post 1 & 2. Thats the tool I am talking about. Other methods are obviously cheaper but are they as accurate or more accurate?
 
Thanks Brent. I'm tired of dragging those old Dunlop gauges around.....
Ordered a set of Toe Plates
 
This is the one I made. I use two straight pins pushed in the tread, set the pointer on the toe in fixture, push the car forward so the pins are on the front side of the tire, move the toe in fixture to the front of the tire and see the difference whether to toe in or toe out!
