Re: Toe-in Adj. tool
My experience with local tire stores for Model A work was not good. The major chains and the local garage all told me that they could not check the toe-in on my car. Most of the reasons were that they didn't want to scratch the paint !
I decided that I would check it myself, and after using the instructions from the Ford service bulletins/Marco's web site, I did it myself. The driving improved after the adjustment and I have more hands on experience with my car. Marc |

The toe in spec is given at hub level or the center of the wheel. The gauge indications are intended to compensate for the fact that you are not measuring at the center of the wheel so they are not ruler measurements. Changing the chain length would also affect that compensation. The shorter the chains the more compensation necessary. At true wheel center no compensation is necessary so ruler measurements would apply. |

Re: Toe-in Adj. tool
You can't measure the rear of the wheel- tire toe in any higher than the level of the wishbone-radius rod. Wheel and tire size will also effect the distance from the floor . I set mine at the level of the wishbone. The center of the hub would be optimum. If the frame is sagged or the motor mounts are allowing the engine to ride low, it will effect the level of the wishbone and the outcome of any adjustments that are made . Common sense tells me that there is No exact level from the floor that will be correct in all cases, Too many varyables.

Re: Toe-in Adj. tool
The measurement is at 6 inches above the floor.

Below is pic of the tag from my original gauge. Have you seen an original done differently?

Re: Toe-in Adj. tool
The service bulletin gives the toe in spec with no mention of any special location so the assumption has to be to common standard which is wheel center. The reason for measuring below center as Purdy states is to clear suspension hardware. The Duby gauge was designed to read below center and compensates for the distance from center with the gauge that reads toe in inches not true inches. The chains can be any length so long as the gauge compensates for that length. I agree Marco's explanation seem to indicate otherwise but the reference does not indicate that the dimension or gauge are other than standard. Hopefully he will weigh in with any other source. The Duby gauge assumes some wheel height to the center so some compensation for height may be warranted. The service bulletins are from 1928 so it's possible a 19 inch wheel would be slightly different. I did make a quick check of some moderns for reference. The center of an Escape is exactly the same as a 19 inch Model A, a Mustang is lower and my truck is higher. I don't have a car with 21 inch so I can't check that.

Re: Toe-in Adj. tool
I realize now that differenmt tools for setting toe in have different instructions for their use. Mine is just a cheap one and not like the original design. I won't bother to go out to the shop and copy the instructions. No harm meant.

You gotta' smart dog, too! When Chief got a "new" Model A going, after a 16 mile trip to town on the smooooth highway, he'd look at the front tires for wear/scuffing, then decide if he needed to go to Buddy Bogg's Local Unauthorized Ford Place for some alignment "TWEEKING!" Then off to"The Little Gem Cafe" for Chicken Fried Steak! Bill W.

I reviewed some of my material again and did SEVERAL calculations to see how it played out and it's pretty clear my assumptions were correct. First, the camber calculates out to 2 degrees +/- (per wheel) when the cars were new based on measurements provided. Now, when Ford implemented the use of alignment equipment in 1936 they specified a MAX camber of 2 degrees on Model A's and many other models. They specified the toe-in at 3/32" which is very close to what I suggest on my page for taking the measurement at the tire tread fore and aft of the centerline. In addition to the measurement provided in 1936 they included a footnote regarding toe-in and stated that toe-in is directly relative to camber which I had also read in my old Dykes manual. Ford stated that for all models as of 1936 the the toe-in should be 1/10 of the camber. That would mean when they were new the toe-in would have been at .2 degrees per wheel. I'm emphasizing "per wheel" in case anyone else wants to run their own calculations to confirm. When specific dimensions are provided as in the Bulletins they include the total difference between the two wheels. That difference must be divided by 2 before converting to degrees. As a final note, in 1936 Ford specified a minimum camber of 1/4 degree was acceptable as long as there was no more than 1/4 degree difference AND the right wheel never has more camber than the left wheel. If one had the minimum camber the proper toe-in with my Duby gauge would be 1/128" or essentially zero. I bring this up because most folks probably have 1 degree or less on their camber so maximum tire wear would require a reduction in toe-in from the new car specification .

Re: Toe-in Adj. tool
That 2 common pin method was mine.. I have never had any problems with it. Been doing it for over 60 years.

Re: Toe-in Adj. tool
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!
I have used this on four Model A's and have been very satisfied! |

Re: Toe-in Adj. tool
Toe-in plates work pretty good.

Re: Toe-in Adj. tool
I used a 1" round spring loaded curtain/shower rod and it works just great. Kinda like yor flat rod.
