Drum/Thickness sander

Why oh why did I wait so long to build this? It has been a joy to have in the shop since I finished it a month or so ago. Here’s the little beauty:

Built almost completely with what I had on hand. 2×4 frame, 1/2 hp motor spinning at 1725rpm. 5” MDF disks on a 5/8” cold-rolled axle. No velcro for the sandpaper, just wrapped around the drum. Adjustment is via a piece of 5/16” all-thread I had in the shop. The table is 12” wide with a usable sanding of 11” (if you get too close to the edge of the drum, the sandpaper will get knocked loose). I plug the shop-vac into the “hood” and it does a really amazing job of keeping the dust under control.

Total cost was about $50 with $25 of that for the link-belt I got at Harbor Freight.

I wasn’t hard to build. Cutting the disks on the bandsaw then truing to the table took the most time.

The thinnest I’ve sanded so far is 3/32”. That was actually by accident. I had re-sawed a piece of stock slightly more than 1/8”, figuring that by the time I sanded out the tool marks it would be 1/8”. Unfortunately the marks left by the bandsaw were deeper than I anticipated so I ended up at 3/32”. Which I thought was pretty impressive all things considered.

So I would recommend taking the plunge if you are even remotely thinking of having a thickness sander.

Wow! I would’ve never considered one of these shop-built.

It would be really awesome to see under the dust cover to see how you constructed the drum.

Excellent work!

Terrific job!
How well does the table stay parallel with the drum when lowering/raising it?

And I hope your going to put a guard on the rest of the belt down to the motor.
Stay safe.

Well done, Bill. Like you I don’t know how I managed before I built mine.

No plans for any additional belt guards. What’s life without a little danger, eh? (I even took the blade guard off my table saw, shhhh, don’t tell anyone.) 8-)

One end of the table is fastened with a piano-hinge. That worked better than a couple of traditional hings since there was a lot less play.
