I have trouble. When I cut a board over 3" in width the cut seems to tail off to the right by perhaps a 32nd. I purchased the saw a couple of years ago at HD as a reconditioned item. I had no problems until I tried to cut some 4" wide boards. On occasion I am able to get the saw to cut at 90 degrees, but I am not able to forecast when it will happen and when it will not. I have taken the fence apart and put it back together sevaral times. I can see no problems with the way it mounts to the base. Has anyone ever had a problems like this?
