I had my wheels in pretty good shape, but I ordered a dishing tool to make sure everything was all right. I loosened all the spokes on the back wheel and started from scratch. After I got both sides down to around 45#, I started dishing the wheel. I had to pull the drive side over about an inch. I kept taking half turns, then taking the wheel off the truing stand and using the dishing tool again. After doing this several times I finally got the wheel centered. Now comes the problem, by the time I got it centered, I have the drive side up to 137# and the non drive side is anywhere from 51# to 76#. If I pull the ND side up the spokes on the drive side will be to tight. If I put some slack on the drive side and take up the ND side the wheel wont be dished right. I hope somebody can tell me what to do. I worked on it for 6 hours yesterday and another 4 hours today.
