I got sick of wondering, is my blade as sharp as it could be? Is the angle correct? So I made a jig for that!
Now I know that every blade isn’t always Ideal at 30 degrees, but it’s a great starting point. The adjustment screw is a 6-32 thread and I figure every half turn of the micro adjusting screw, moves the blade about .005 closer to the grinding disk. In the last 2 photos you can see the edge after just 3 passes and how far off I actually was. The last photo shows a perfectly straight 30 degree wedge. I cleaned up the feather hairs on the diamond pad. She cut’s like a hot knife through butter now.

Very clever as others mentioned. You should submit you idea to some of the woodworking magazines. I would guess you would win a prize for the best jig.

How do you ensure that the edge of the blade is perpendicular to the side of the blade?

@LJackson, I could always add a strip to one side to insure the blade starts out and stays perpendicular, but my goal was to make sure the blade didn’t move once I began and it doesn’t. Besides the lateral adjusting lever on the frog will compensate for any irregularity that I may have built in while sharpening. Those were my thoughts at the time!
