I did the math,,, and although it is not 100 % exact,,, it is close enough,,,, if the points on the rim front to back are 5.725 inches apart where you measure to the square, the degree of toe in or toe out equals 10 times the different in front and rear measurements as measured in thousandths of an inch. example,,, if the difference between the front and rear measurements is 0.062 thousandths of an inch,,, the toe in or out is 0.62 deg if you want to do your own math,,,, the deg of toe in equals the tangent of the opposite side divided by the adjacent side. the tangent of 0.62 = 0.010821 opposite side divided by the adjacent 0.062/5.725 = 0.010829 or you can do an inverse tangent function Tan =931 power ( 0.062/5.725)= 0.6204 or very near 0.062 *10 = 0.62 the way the inverse tangent function looks may vary pending on your calculator. one last thing,,,, when measuring it is best to have the wheel placed on a grease plate, which is made by putting a few pumps of grease between 2 smooth aluminum plates, or similar materials.. this is probably worth archiving. boyd young ________________________________ Message 6 _____________________________________ Time: 12:17:59 PM PST US From: "Pat Ladd" Subject: Re: Kolb-List: Re: Reklaw Fly-In Hi Travis, nice pictures but there is a problem of conflicting requirements here. With the camera attached to your head, and your head constantly moving, as it should be if you are keeping a proper watch for other a/c the picture is constantly on the move. Secondly. The main thing anyone with a camera is taught. Don`t zoom in and out and don`t constantly pan. If you must pan, do it slowly. Two irreconcilable requirements. Perhaps fixing the camera to an attachment on your shoulder might be a part answer. Looked a nice fly in.
