First off, I want to thank some of the other LJs that posted pictures and ideas of thier drum sanders. Blake, Billp, and Rareddy are a few. By looking at their sanders I got a good start on my design. It is a combination of others ideas with my own creativity added. I got alot of enjoyment out of building this. It was fun to do the engineering and developement of the construction.
OK for some stats, It will do boards up to 18” wide, from 1/8” thin to just above 4” thick. The sanding drum is 4” in diameter. I put on a half horse motor (1725 rpm) and 3” pulleys on both the motor, and the drum shaft. The shaft is 5/8” and I used some left over Power Twist belt.
The main construction is pine 2×4’s but the critical wood components are red oak. The table is two 3/4” plastic coated mdf pieces laminated together with an oak boarder.
The dust hood is made from 1/4” luan plywood and I cut in a 4” dust connector. The motor is mounted to 3/4” plywood and attatched with a piano hinge. The weight of the motor is the only tensioning of the belt.
The table heighth adjustement is a 1/2”x 9” carriage bolt with a 5” hand wheel connected to the threads.
Most of the mechanical components were purchased at my local Farm & Home store. The motor, switch, and hook & loop adhesive base and sanding media was bought from Grizzly. I have just under $200 in this rig.
IT WORKS GREAT !! I connected it to a 4” dc port and ran several pieces of 3/4” pine through it. With the dust collector running, there was absolutely no escape of any dust. Plenty of power, and easy to feed and retrieve stock. I’m glad I built this, and now I’ll build a mobile base for it. GOD BLESS. KHOP

Very cool build. How do you push the stock through? does it want to shoot out with the rotation of the drum?

You really thought this out! I’m sure its very gratifying to use a tool that you made yourself.
I also would like to know how you feed the stock through?
Great Job!!

Sweet, I love homemade machines.
I looks like the nut for the adjustment screw is welded to the bracket. Nice handwheel too. I need to learn to weld.
