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.

I had this same problem with my Jet contractor’s saw, which is, I think, essentially the same saw. I took everything apart and put it back together and it turned out that the mating pieces of the trunnions were not perfectly put together. Once I had everything set up the way it was supposed to be, I had plenty of room for adjustment.

I think you should try to tighter/snug one corner bolt, (to act as a pivot point), then go about adjusting the others. Just my opinion.

Contractors saws can be very problematic to tune up because of the way the trunnion assembly works. This article may be relevant to the problem you’re having. My first saw, a beat-up Jet contractors saw, drove me nuts and I wasn’t clever enough to fix it myself, so I took it to an expert— he got everything in the right plane and life was good. May not be the root of your problem, but it’s something that’s unexplained in the vast majority of tune-up articles written.
