This is my first post here.

I had been collecting information and reading different plans on building a thickness (drum) sander. I felt the need while working on a project that had to resaw thin materials and smooth them out. It is going to have a power feed conveyor.
Anyway, the initial plan of an 18” wide one grew to a 29” one.
I finished it a few months ago. It took a bit longer because I had to do new electrical wiring in my basement shop just to be able to run it.

Here are two videos, one showing it half way through the building progress, one showing it in action:

It has a 2HP farm duty motor and a 150lb/in conveyor motor. The maximum width I can sand is more than 28.5”.
I have loaded the progress photos as well as the finished photo and three videos showing the sander in action at the following link:

Very nice sander. Where did you get your one piece bottom sandpaper, if it is indeed sandpaper. I wouldn’t know where to get paper that wide. Welcome to LJs.

Thanks to all for the kind words.

Yes, it works well (much better I was hoping for). Since I built it, every board I plane goes through it before dong any other thing. And it is accurate. The following two photos show the different sides of the board I just sanded in that video:

As for cost: it was around $600 for all the parts (which were new), and I have some left-over parts (bearings/chain/sprockets). I don’t know how much time in put into it, but half of the time was designing it :-)

I got some of the parts from (although after that I found a local supplier with lower prices). As for the belt, it’s 24”x60” made by klingspor, you can get it from

I’m slightly jealous of people who are able to build these type of awsome machines. Great job. You’ll get alot of use out of this and I’m sure it will give you greater satisfaction.

I have a Delta (18-36) , it looks like yours works better than it does! Excellent job! Your raising mechanism looks much more robust than the Delta. I have to think you spent a good chunk of your budget on the power feed electronics and motor. I started to build one myself then came across a deal on the Delta and never finished it. I had the spring rollers for mine that look very similar to what you did. Mine looked a little more like a 36” Performax and is made of 1” X3” steel tubing and 3” steel pipe just acme all thread (Enco) and nuts for the raising mechanism. The sprockets and chains also came from Surplus Center. I hadn’t worked out the power feed I was hoping I could find a treadmill or rotisserie with a variable speed drive I could scavenge.
Anyway kudos to you for finishing it and engineering a fine working machine! I know you will love it. BTW Welcome to LumberJocks!
