Message-ID: <129@rocky2.UUCP> Date: Wed, 25-Sep-85 22:51:44 EDT Article-I.D.: rocky2.129 Posted: Wed Sep 25 22:51:44 1985 Date-Received: Tue, 1-Oct-85 10:25:28 EDT References: <5490005@acf4.UUCP> Organization: Rockefeller Univ., N.Y.C. 10021 Lines: 36 To test if your rim is centered between the locknuts of your axle, just place your dishing tool against one locknut and the side of the rim. Tighten the set screw on the tool and then put the tool on the other side of the wheel. If the tool presses against the rim and there is space between the tool and the locknut, then you know that the wheel is built with too *much* spoke tension on the side that you now have the tool touching. If the tool touches the locknut but cannot touch both diametrically opposed points on the rim, then there is too *little* spoke tension on that side. This holds for building front (symmetrical) wheels as well as for read (asymmetrical) wheels. You will find that five-speed rear wheels need a little less than twice the tension on the right as on the left and that six-speed rear wheels need almost three times the tension on the right as on the left. You could improvise a dishing tool with two stacks of books on the floor. It takes more patience and care that with the real thing, but it works. Place the wheel on two stacks of books at diametrically opposite points on the rim. Then measure the distance between the locknut and the floor. Flip the wheel and measure again. Before you are ready to measure how centered your wheel is, be sure that the rim is quite straight. Otherwise, the test is meaningless. Whatever you use as a tool, the amount that the wheel is off-center is half the discrepancy shown by the tool. Good luck.
