I notice today as I sharpen my 12" planer blades they had a high spot in the middle of the blade. I went through all the steps to get the machine ready to sharpen the blades. I took the diamond truing tool the the wheel first. Then the stone grader to remove the grooves from truing the wheel. Follow by setting up the jig as per the manual. My thought is that my hand pressure is causing the high spot in the blades. Any other thoughts?
If you follow the procedure for setting the depth of cut, and then follow through until the blade carrier is fully in contact with the supporting beam, it should be straight.
