I am having a difficult time “squaring up” my saw blade to the miter slots. I have loosened up all four bolts that attach the grunion to the underside of the table saw top. There seems to be almost “zero tolerance” in moving this whole carriage. I have used a crowbar as leverage and can get some movement but not enough. I have a digital read out that shows I’m off by as much as .033 of an inch. This is unacceptable. Can anyone help me? I am making a cross-cut sled and cannot go any further on it until I can get the saw blade square on the table top. I have been dealing with this problem for months. The manual does not give any written communication as how to make this adjustment. I’m desperate for any advice from fellow woodworkers.
