I needed to cut four panels the same size so I decided to use the tablesaw fence to get the right length without any having to measure each panel. I attached a block to the front end of the fence so I wouldn't trap the piece between the fence and the blade. Then I placed the crosscut sled in the right (or in this case, the wrong) miter slot. Since the panel was almost as big as the sled, I didn't notice anything was wrong until the blade hit the fence at the back of the sled. Oops, now I have a really short sled that only works in the right miter slot. I guess I'll be making a new one this evening.
