The screw holes holding them down could even be slotted so the width of the slot could be adjusted for various thickness blades. My fixture also has a key on the bottom so it aligns with the miter gauge slot in the belt sander. Then all I have to do is feed the blade against the belt one end at a time to grind the 20º angle. It's quick, accurate and makes a hell of a strong joint.

Tom My 12" sander's disc is to far away from the tables slot to work like yours. I'm going to have to build another jig just for grinding blades.
I have a piece of of 1" square stock I'm going to drill holes in to except three 3/4" diameter X 1/2" deep barrel neodymium magnets that should hold the blade to the 1" steel, which will be clamped and silver soldered to the grinding jig's base at 20 degrees.
I'll have to make an attachment for the jig that's long enough it allows the blade to reach the 12" sanding disc and ride in the table's slot.
Tom I got this idea from watching your video. I plan on educating myself as the days go by by watching more of your videos and reading your posts, I'm sure I will become a better hobbiest by listening to what you have to say. Thanks
