Simple to make and use Toe-In gauge 5 Attachment(s)
I was trying to figure out an easy way to check the toe-in on a friend’s model A to see if we could stop the “Death Wobble”. So I watched a couple YouTube videos and came up with an idea to make an inexpensive and simple to use toe-in gauge.
I’ve attached a few pictures so it should be pretty self explanatory. The gauge is put between the tires at the front of the car at the height determined by the chains, then a mark is put on the inner, sliding, PVC pipe in line with an index mark on the movable coupling. The car is then rolled FORWARD (as pointed out below) until the chains show the gauge is again at the same height from the ground, Another mark is put on the sliding PVC pipe using the same index mark on the movable coupling. The distance between the marks is the toe-in, or toe-out. You have to think about what you’re doing to make an adjustment. It get's confusing. Looking at the gauge when it is at the rear, and you are under the car, the second line you make has to be to the RIGHT of the first mark for it to be toe-in. If it is to the left, you have toe-out. Toe-in relaxes the gauge as the tires go the rear making the gauge longer, thus the mark will be to the right, and toe-out compresses the spring making the gauge shorter and the mark to the left.. The information you need to make one is as follows:

Not to mention it would be kind of hard to roll the car backwards starting with the gauge at the front? |
Re: Simple to make and use Toe-In gauge Or something like this.

Re: Simple to make and use Toe-In gauge You could make something like that out of plywood and make sure the arms were long enough to match the radius of the spot where toe-in is measured.
Edit: I mean the tool in post #4 |
Re: Simple to make and use Toe-In gauge Nice work! I'm always glad to see individuals come up with these kinds of helpful self-created things. It is especially pleasing to see it does not require a software app and a computer screen.

Re: Simple to make and use Toe-In gauge Thats pretty much the same as the 100 yr old spring loaded gauge I have.

Re: Simple to make and use Toe-In gauge A very neat idea and tool you created. A couple of questions.
First to get the correct measurement for toe in, doesn't the gauge need to be at the center of the wheel at the height of the king pin for each measurement front and back? Second, would you need to make more than one measurement check? As you adjust the tie rod you are changing the measured dimension at the front as well as the back of the wheels. |
Re: Simple to make and use Toe-In gauge That's interesting, I have the manufactured gauge and you put it on the front and move the car forward. It has a gauge that you read when it's rolled forward. I took a shower curtain rod that's already spring loaded put the chains on it and stuck it in the front, marked with a pencil when the two rods come together and then rolled it back and marked it again and then looked at the measurement and it gives you the reading. The gauge we bought for the club tool closet was around $120.00 although I've seen them for less. Great job making the one you did.

Re: Simple to make and use Toe-In gauge You can save money with the way I do it. Two common pins and a tape measure. Place pins in tire tread and measure back then roll forward and measure again. Does take the help of your wife or a friend. Total cost zero.

Re: Simple to make and use Toe-In gauge TJ, great post. Thanks. Neat tool.
The tow in needs to be measured at the same height front and back, thus the chains. It does not have to be at the same height of the hub but should be high enough to get a good reading. If you adjust the camber, not easy on a Model A, or any other steering geometry, remember to check the tow in last as the other setting will change the tow in. |

This is the one I made, have posted it before. I use the pin method and have good results!

Re: Simple to make and use Toe-In gauge I think you did a great job. Thanks for sharing! An old alignment man told me to roll the car back and forth at least two car lengths after each adjustment and check again. Makes sense with these old less than perfect tolerance cars.
|
Re: Simple to make and use Toe-In gauge Yblockhead, you are correct. I misspoke. The car does need to roll forward after you install the gauge. My old mind reverses things occasionally. As I said, you have to think about what you are doing.
I hope someone gets some benefit out of it. |

I like to see people make their own tools. |
Re: Simple to make and use Toe-In gauge The measurement is between 1/16"-1/32" difference from back to front. I always think about a bent rim which will throw the measurement off. So, here is how I do it:
Drill a whole in a block of wood to tightly fit and hold a sharpie pen Jack up one front wheel at a time just off of the floor Place the sharpie in the block on the floor and the point of the sharpie to a flat spot close to the center of the tire Turn the tire one revolution slowly with the sharpie against the tire creating a centerline Take your measurements from the centerlines This method will compensate for any runout from your rims I have used this method several times with great success |
Re: Simple to make and use Toe-In gauge maybe i like things simple and crude, but here is what i did. a piece of 3/4 pvc with a cap on each end. tap one of the caps 1/4 20 and put in a screw 1 in. or more. put this in the front of the wheels and adjust the screw until it just touches. move the the back and the distance between the screw and the wheel is the toe in.

Re: Simple to make and use Toe-In gauge The runout is an important thing to consider. It is also important to have the height where the measurements are taken the same front and back. The camber will effect the measurement if the height is not the same. As far as the runout is concerned, if the measurement is taken at the same point on the tire front and back the runout is taken out of the equation. That is what is nice about TJ's tool. The location does not change moving from front to back and the chains assure that the height remains constant. Using his tool or a similar one, make the measurements on a flat surface like a garage.

You make an excellent point that got me thinking, and so is this one: Quote:
I said it was easy to make and use, not understand. :-) Thanks for the input, Guys. I appreciate it all. |
