In the process of making the cabinet for my wife, I needed to re-saw a piece to make the bottoms of two drawers. I set the saw up and made the cut. Well it came out not so good. I made another one, same result. I started to get mad and then I looked closer at the blade, I think you know what is coming, the table was just a nudge off 90 to the blade. I fixed that and made another cut and yep, that did it. Tonight I have two drawer bottoms.
Point is, don't get mad. There is usually a fix to the problem, just find it and fix it.
