I have a 6×48” belt sander, and when i try to use it to chamfer the corner of anything, I often get an uneven chamfer on it, coz my ability to visualize the angle is not what it should be, and also, without equal pressure across the width of the angle causes one end to have a thicker cut than the other.

So, I built this jig to clamp onto the sander, and be able to set my workpiece into it, and then apply pressure until the sanding belt does its job.

The jig has an adjustable ‘throat’ so i can change the thickness of the chamfer. Of the two 45 degree angle throat plates, one is Masonite and the other is 3/4” and is adjusted by way of wing nuts.

The jig is fitted to the width of the casting of the sander, and i use clamps on opposite corners to attach it to the sander. Works real slick.

This is going onto my list.

I had made a mini-jig that just sat over the corner to act as stop for a hand sanding block. Way slow and still not as good as I wanted as it was sanding cross grain which required another sanding step before finishing.

Right now, I have just settled for square corners. This will give me another option.

Great jig. A few minor mods and it could be used for many other things too. Cutting splines for example.

Thanx for all the compliments, everyone.

Mike— I’ve skinned my finger tips and knuckles too many times (they also get scraped on the concrete floor as I drag them along). It’s that damned sanding disc attached to the front of the machine, that i forget about and lean on or into, that does the real damage. I’m gonna make a cover for it.

Rex… cutting splines is what I really want to do. That’s next.

BTW, I’ve got a million of ‘em!
