The problem I'm having, well two problems, the blade will not stay vertical. I have tightened everything up that I can find to tighten. Also, when raising or lowering in fine increments, on the up, no problem. But on the down, it has slop in the spiral screw that raises and lower it. I have tried to keep that acme thread clean and lubed with paraffin wax but it still "hops" when trying to lower it a tad. I'm referring to when I'm doing a dado or rabbit cut and have to adjust in fine amounts. I can bump it up but I can't bump it down without it "dropping" more than I want. So I have to raise it back up to what I'm wanting. It's just a frustration that I'm trying to avoid. I do have a sled for the table saw but it might be time for a new one. I actually like the saw and it's mobile base. But I get fed up with not being able to attain the degree of accuracy that I used to get. Oh well, as you said, good enough for this old codger.
