Benchtop Thickness Sander

I built this benchtop thickness sander over the weekend. It has a 16” bed and a removable dust hood, which also serves to keep my fingers away from the action. The best part is that I was able to scavenge most of the parts. I only had to buy the bearings for a total of $20!

I plan to add a safety guard to cover the belt and I’d also like to convert the drum to a hook and loop system (I’m using carpet tape for now).

It works really well and leaves a very even surface on thin panels.

looks good. I’m waiting on a pair of pillowblock bearings to build myself a similar unit.

Came out very nice. If it works, the project is a success. Enjoy your new machine.

Cool. Very nicely done, but get that belt guard on ASAP. Also, you might consider putting a cover on that switch to keep the dust out. Otherwise, great job and I admire your ingenuity!

Andreas – You woodworking skills far exceed mine. However I must point out little fingers can get through the gaps on that switch without a cover and the results could be …...... ???

Also NO guard on the belt – I am speechless at your carelessness . Your other projects are so clever and beautifully done and now this.

Yeah, I’ll definitely make a guard to cover that belt. That’s my project for next weekend :)
I also plan on putting a faceplate over the switch. I didn’t have one that fit properly so I have to go out and buy one.

I love it! Is it a repurposed motor? If not, can you give me some details on it? I’ve been wanting to build something similar, but have no idea what to use for a motor. Thanks!

I’m liking it! What do you mean you use carpet tape for the drum? You mean you wrap double sided carpet tape around it and then the sand paper? It looks like the end of the sandpaper is tucked into a slit on the end of the drum. Right?

Supercubber: it is a 1/2 hp repurposed blower motor. 1/2 hp seems sufficient for this sander but I would probably use 3/4 hp if you had a wider drum.

StumpyNubs: There is a small slit on both ends of the drum where I tuck the ends of the sand paper. I also put a strip (about 4”) of double sided tape in front of the slit to keep the paper from popping out when the drum is spinning. The rest of the drum has no tape. This works well enough, but it isn’t ideal. The sand paper tends to bunch up on the tape if I haven’t wrapped the paper tightly enough.
