I just finished building a much needed dual use drum sander with culled woods from Home Depot. Cheap, cheap, cheap. I needed a tool to flat sand my clock gears. The gears are small, less than 12 inches in diameter, and I don’t want to pass them through my De Walt planer anymore! This sander is a combo drum and V sander. The design is borrowed and adapted from numerous home-made sanders available on the internet. I used 3-1/2” PVC as the drum with oak caps. It’s extremely light, strong, straight and uniform/balanced (no wobble) which places less burden on the 1/2 HP motor I had sitting in storage. The belt is 3/8” X 40” and purchased online for 3 bucks! I adapted a some scrap metal (old heat vent pipes) to collect dust during thickness sanding mode. Oddly enough, the electric switch was the most expensive part! The table adjusts with a simple 3/8” threaded rod device (see the photos). In V-Drum mode I add table annexes and adjust the level of the sanding drum using the same leveling device used in the thickness sander mode. By adjusting the table I expose the sanding drum through the table annexes. Works great and does the job.
