Boy, am I glad to have this done! I have been wanting a thickness sander for over a year now. I have ended up with so many small pieces of wood that I would love to use for boxes, but I had no way to dimension them. For a long time I thought about saving up and buying one, but the “cheapest” model is about $600 bucks, which seemed way too expensive for such a simple machine (it’s just a spinning drum!)

I have been in to building my own shop machinery lately. If you haven’t seen my router table, check it out too:

Anyway, I originally saw a similar design on another blog (which is no longer active and the old photos are gone.) But seeing this design what made up my mind to just make my own. I really like this design because it seemed simple and just the right size for my work. A couple other Lumberjocks have built other versions before mine and answered questions for me (thanks).

Here are some other Photos:

Construction:

  • I started by building the frame out of plywood and biscuits. I primed it and spray painted it teal-blue.
  • The table is a laminated scrap I got for free from a cabinet shop. I lined it with Beech (all the bare hardwood you see is Beech.)
  • To raise and lower the table I built a simple mechanism with a piece of wood and some common hardware. At the top of the allthread there is a cap-bolt (with a round top) that pivots freely like a socket joint in another large nut that I found.
  • I ordered the pillow block bearings online. The drum shaft is drill rod from the hardware store.
  • I chopped up some 1/2” MDF into squares and then cut them into circles on my bandsaw with a impromptu circle-cutting jig. Then I stacked them up on the shaft with glue in between each circle and clamped them together to form the drum.
  • I installed the motor, switch, pulleys, and link belt. Then I started it up and ran blocks of wood with sand paper stuck to them under the drum until it was uniform and true to the table.
  • I built the dust hood out of Plexiglas and hardwood. I made cut-outs to fit over the pillow blocks and inserted a couple of rare-earth magnets to keep it down (but still easy to lift off)... see photo above.
  • I covered the drum with epoxy to make it smooth enough for the self-adhesive velcro to stick to (which I ordered from Grizzly).
  • I also ordered a 150 grit 3” wide roll of hook-n-loop sandpaper from Grizzly which I cut and stuck to the drum.
  • I had a small rolling cabinet that was the perfect size which I am using for the base right now.

Stats: The drum has a 4” diameter and is 12 1/2” wide. It has a vertical capacity of about 4” tall for running entire small boxes through. The motor is 1 hp, 1725. The pulleys change the speed of the drum to about 2200 rpm’s.

It seemed to work perfectly on my first test piece! It runs very smooth and quietly and is dust free. And by the way, feed rollers/belts are over-rated. It is very easy to just push pieces through the sander, and the drum keeps them down flat against the table. I just use a flat push block to push the piece through.

Let me know if you have any other questions. This is a relatively simple and cheap project for such a handy shop machine.

Good looking piece of equipment Blake. I really admire those who can make their own.

thats great, building a drum sander is something I’ve thought about doing for a long time but haven’t got to yet. your’s came out great too. those big drum sanders do seem overpriced for what they are so its good that we can always resort to making our own. thanks for the post.

Blake,

You did well with this. This is a tool that will be very useful in your shop. I would love to have one of these but, like you am put off by the price tag. I may have to look into building one of these as well.

Thanks for the post.

Can you come to my house and build one? That thing is great! I had looked at one on line someone had built before and wondered about building one myself. I make shaker boxes and it certainly would be handy. Nice job Blake.

A drum sander this size would cost with shipping a little over $1100.00. I really don’t care what yours cost. You manufactured it from a drawing or an idea and its just the way you wanted it. Perfect. WoW what a undertaking. Your the Man!

Very impressive. Building stuff is one thing, but building your own power tool is DIY-extreme! Nice job.

Excellent Blake! I want to make one now. Question: Does only one side of the table elevate?

You have done a wonderful job building this sander. The only thing i would recommend is that you build a guard to cover the drive belt.

Gizmodyne: Yes, the table is hinged in the back.

Scott: I thought about it but it is relatively out of the way, and I am the only one that will use this machine. But I might do this in the future, thanks.

Great job Blake! I know what you mean about it being easy to push through by hand. My first thickness sander
was only 3” wide! I won’t give my feed system though.

Again, Great job!

That is awesome. I will be contacting you when I build mine some day. How much time did you have into it. Time is one thing I’m short of these days.
