I am getting a lot of tear out jointing an edge. I tried wetting the edge, it did help a little. I read about making a wedge the length of the jointer's fence and taking passes at an angle. Will this make enough difference. I didn't get very much tearout when I jointed the boards flat. To say the least I was surprised at how much tear out I was getting and I just had the blades sharpened. Any suggestions. Thanks
