Thread: Magnetic sanding block with clamp

After getting cramp in my fingers from holding the razor while handsanding I decided to make a magnetic sanding block too. It's a pine block roughly measuring 13.5 x 8.5 x 3.5cm. The two magnets have a diameter of 3cm. I used plexiglass to support the spine. Both the plexiglass and metal are taped to the pine block with doublesided tape.

For the surface I first used plastic from a CD box, it worked great but wore out quickly. Then I tried 2.5mm thick metal but that left the surface hardly magnetic. Finally I used 0.3mm thick metal. Not sure how long this surface will last but it works great.

With the sanding block clamped to my desk I can hand sand using just one finger

Very nice. I need to make myself one of these.

Nice job! Where did ya get the magnets? I also need one of those setups

The magnets were bought at the actual shop of Magneten winkel. I can't tell from their list which one I got though. They're actually a metalshop and they have a small metal board hanging from the wall with all their magnets attached to it. I just pointed at the ones I wanted

Excellent idea i'll be making one as well. what did you use to recess the holes for the magnets,did you glue them in as well?

I can't take credit for the idea. I looked at some other sanding blocks and changed the design somewhat.

The magnets aren't glued in. Because of the doublesided tape I can take everything apart and replace items. I didn't want too much of a permanent design.

I have a plunge router attachment for my dremel which I used for the recessed areas.

If you're in the US American science and surplus has rare earth magnets pretty cheap.
