My under $100 wide drum sander (a work in progress)

I mill wide boards. I have been slipping some of them in the side door of a local cabinet shop when I need them surfaced, but that is getting to be a hassle. I decided to make a wide drum sander. Not really a thickness sander since I mill my own lumber, just a sander to take the sawmill marks out. I had just about everything. A 1 1/2 horse motor, some wood for the frame, belts and pulleys…I did have to buy a couple pillow block bearings.
Here it is almost complete (I still need to built a dust hood) I added a big switch on the side of the frame not shown in the picture, but I have a video I am posting showing me hit the switch. The motor is just hanging from a heavy hinge and the belt like a table saw.

I built a sturdy frame. The drum is fixed and the table raises to the drum.

This screw raises the bed.

It does a pretty good job, looks like it would sand flat to me with the bed all the way up. I have the wrong paper on in this picture, that is just emery cloth I had handy to see if the worm gear clamps to hold it to the roller was even a good idea.

It will sand 25” wide boards. It is set up right now to sand from 2 1/2”-0” thick, my most common need. If I want to sand thicker I can just add riser blocks under the pillow blocks.

This is how I made the roller. I turned some wood plugs and spaced them on the shaft. The shaft is threaded rod and the wood disks are jam nutted in place.



A test run on a piece of osage orange. I was just trying to see if the drum built up too much heat (something I was worried about using PVC pipe) I figured if anything was going to make it hot that hard osage would…it got warm, but not hot.

If you have ever worked with osage orange you know how hard it is, something like cherry/walnut I could pretty much thrown though the machine.

It did a pretty nice job of finishing.

It is not 100% done yet, but any questions, comments, criticisms are welcome.

Great looking machine!

Thanks for the post.

I want a 60 inch version.

Do you see one this size in your future?

Sawdust, just playing around I did find if I was taking alot of material I would get visible marks where I stopped to get another grip (I am just at this time pushing the stock through manually, may look at power feed some day). But just a baby bite for the last one and the pieces come out smooth even hand feeding. So the last pass is just barely touching the roller and no problems with the few pieces I have sanded.

How is the kickback factor without having a conveyer?

I felt pretty comfortable that a kickback is not likely….but watch the video again I never stand behind the board, I am beside it for safety reasons. 2 things, one that was just test piece that normally I would have just ran through my planer. I am just going to use this for boards in the 16”-24” range and 6’-12’ long, I am not sure with my holding on the motor even has enough power to throw one of those. I intentionally jammed it one time and was able to hold on and make the belt slip instead of kick back. 2 I will most always have a helper, I will feed in and the helper will pull out…having said that I have already started a conveyor (scrapping a heavy duty treadmill) I will update as that comes along. Safety is always a concern of mine though and I am being very careful as always.

Very cool. Great project but you really need a respirator or at least a good fan for all that dust!

Blake that was just a test. I am building a dust hood to hook up to the dust collector…Phase 2…power feed. I got my “free” treadmill parts. I will update when I get the power feed running.

An excellent tool. I have been kicking around the idea of drum sander or thickness sander around for a while. After seeing this one, I may need to start to act.
