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?
