Random Tip #2 - Mag-Blocks Cure Clamping Ills - GeeDub - 01-23-2020
I have often run into a time when I want to clamp to a surface that is not well designed for it. I have some stamped saw horses I use that use a "U" channel for the horizontal beam. This makes clamping a pain. I used some rare earth magnets that I picked up on the cheap at Harbor Freight. You can use whatever you may have; damaged magnets, scratched magnets, magnets scrounged out of hard drives; whatever.
You can see the upside down "U" channel here:

I recess the magnets so they are just a hair below the surface. Since I will be clamping on the block I don't want to crush the magnets DAMHIKT (sorry for the poor pic):

The laminated block of ply was a larger blank. I drum-sanded it to the right thickness and then sliced it into four blocks. It fits the saw horses just right:

Now you can clamp away. Of course everything in your shop will be a different depth of cavity but, the blocks do not have to fit perfect, they just have to be thicker than the cavity is deep. I use them several places:

Good idea. Better than using hot glue or DS taped.
