Hey-
Im reading these threads and some use the reference tuning board, what the heck is that?
If it refers to a long, solid, flat board that is used to test and tune the alignment of a car, then I guess I have somewhat of a tuning board. My wife gets so ticked, but I take the oak closet folding doors off, and use them to align the car. The are hard and flat, about 7 ft long or so. I adjust them level side to side, and raise the one end about 3 inches. Am i doing this right?
When trying to align the rear wheels, how exactly do you roll a car down the board without the front wheels on it? If the wood is just dragging on the board, wouldnt the minor surface imperfections of both surfaces effect the way the car turns?
Last, how high do you typically raise the one end of the board to adjust the pull of the car, and are most people using about 3" of pull into the rail for about 7ft?

IT LOOKS LIKE YOU HAVE THE TUNING BOARD DOWN...

I made me a new one out of a 14"X50" mirror. Since the cars are painted on the bottom when I try and do a rear wheel only roll the car wants to stick. If I put a thumb tack under the front do you think it would slide good enough? I haven't used a tuning board for a while. Time to get back to basics.

Got some nickel plated thumb tacks, polished them up and then rubbed down with Hob-e-lube. Took the front wheels off, placed one of the tacks dead center under the front. Marked off the mirror with my lines, and it rolled nice and slow. Now I can focus on that rear wheel alignment. Maybe it will help, sure can't hurt to try.

I just made one out of 8ft melamine shelf-12"wide. I put 2' wide aluminum legs on it with levelers, it worked great.

I keep thinking of ideas for my tuning board (which I don't have yet). I want it to be elevated along a wall. Any thoughts on a 8' melamine shelf on brackets (offset for 3" slope) with glass top (could have a couple small clamps to be certain it doesn't slide off). I want on the wall to save precious floor area. My original idea was to have a board fold up, but this isn't necessary and all that movement might make it not level. Any rate, would like to hear if this is feasible or if it's just bad idea. Thanks

You would need to insure that the board is sloped and level and anchored to something....

That would work. Provide for a way to level it side to side using a level. A small amount of rise is fine, just make a way to keep it on the table. You won't like the way the floor tune's it Go to you tube and search MB4hire. There is a clip of his table in use. Pretty cool. I think I have seen Glenn's too. There's a clip in here somewhere.

I tried making tuning boards out of three materials, all 18" x 6', Marble. glass, very smooth unpainted wood. I then tested several cars and wheel set ups. Marble and Glass are too smooth and don't give a good reading. Wood had enough traction to give a decent reading. In testing, I found out that 7.5 mm wheels need more drift than thin disks of several types. At six feet, i found 1 to 1.5 inches for disks, and 4 to six on wide wheels. Any one else done further testing on this?

Any one else done further testing on this? How did you verify these results? Do you have access to a track? The amount of drift required for a car has more to do with the COG than the width of the wheels. The more aggressive a car is with the COG the less stable it will be and more steer is needed to run steady. Also the type of track will play into it too. The idea of the tuning board is a way to measure the amount of steer. I hope this helps.
