Sanding is not one of my favorite things to do so any tool that can help me speed up that process is a must have in my shop. After searching the internet for drum sander plans and watching numerous youtube videos of homemade sanders in action I decided to build one for myself. I took an inventory of materials I had on hand and that determined the dimensions and design of the sander.

This drum is made up of 30, 3/4” thick by 5” dia. MDF disks that I cut on my bandsaw using a homemade circle jig. These are in turn glued together three at a time and then mounted onto a 5/8” dia. cold rolled steel shaft. I didn’t need to glue the disks to the shaft because friction between the disk sections and the shaft was more than adequate. I can run 23” wide material through this sander at a maximum thickness of 2 1/2”. The shaft is mounted in two 5/8” dia. pillow block bearings attached to the frame. I trued up the MDF disks by gluing 80 grit sandpaper to a piece of 3/4” MDF, mounting it on the table under the drum, and then adjusting the table up until it made contact with the turning disks.

Once the drum was trued up I attached a 3” wide self-adhesive hook and loop sandpaper system to the drum. I ordered several grits of 3” wide loop sandpaper so I can easily change out one grit for another. The table consists of two 3/4” layers of MDF glued together and covered with plastic laminate. It is hinged to the frame with a heavy duty piano hinge. The sander is powered with a 1 1/2 hp ac motor because that is what I had on hand.

I originally adjusted the table up and down with a 1/2” piece of all thread. That didn’t work as well as I had hoped so I replaced it with a scissor jack type of lift using the same 1/2 dia. all thread. That did the trick!!

I discovered that I like making tools to do woodworking almost as much as I like woodworking itself. Wait a minute, isn’t making wooden tools to do woodworking, woodworking?

Nice job! I really like your use of the scissor jack mechanism. You do know these guys around here are gonna steal that design!

Hey guys, steel away!! The jack idea came from opening my car trunk and discovering I hadn’t put my jack back in it’s proper place after fixing a flat tire. I said to myself, self, there is the solution to lifting the table. It makes fine tuning the table height a snap. So, if you need plans, open your trunk and take out the jack :)

Nice job. I think the scissor lift design would work well on a router lift. I have been thinking about my next tool build and may have to use that idea on a router ift. Thanks for posting

Hey GS check out Matthais Wandel’s tilting router a www.woodgears.ca. A honest to goodness router table is my next tool build and I am seriously thinking about his design.

Thanks all for the kind words!!

I need one of these! Looks like I may have to build one. That would look great in my shop. Hmmmmm…..

If you go out of town & your sander comes up missing, I didn’t take it!!!

Looks great! I made one as well (in my projects) and just love it. It is nice to do it yourself because it’s fun and you save a ton of cash not paying for a new one. For my purposes it does everything I want with no problems.

Woodbilder, you feed the material through the sander by hand. I use a push sled, a piece of 1/4” plywood 4” wide and 6” long with a 1×1 glued to the end of it to get the work piece past the drum. You need to take light passes because the rotation of the drum wants to spit the work piece back in your direction. It takes a little getting used to getting the feed rate just right. I have seen guys build these with a motorized conveyor belt type infeed but that is beyond my expertise.

bvdon, I use mine every day and love it also. It was fairly simple to build and the savings over a new one makes me smile :).
