It’s easy to go to the hardware store or tool shop to purchase a drum sanding kit – if they are available. But if the product you need were always on the shelf, life would be good right? Odds are stacked against us that we usually find what we are looking for.
Making your own sanding drum though is a simple and low cost fix. These can be made to any size you desire, and can use and sandpaper grit you would like.
1st, cut 2-4 holes using a hole saw. It’s best to use at least 3/4 inch thick material if you have it. Scrap is fine because you just need the holes. Us a 1/4 carriage bolt with a nut that is long enough to go through all the wheels plus enough lengths to use as a shaft for the jig on the drill press.
Stick the washer, and then the holes on the bolt. Then tighten up the nut to squeeze all 2-4 holes together tightly. Put the assembly into the drill press and sand it smooth. Hold the sandpaper behind the drum with both hands. Pull the paper towards yourself, slowly moving up and down the entire piece.
The next step is to cut a grove into the assembly as seen in the image. You can use a coping saw or hack saw. The edge of the grove needs to be sanded off to avoid the sandpaper making a bubble at the corner.
Now cut a strip of sandpaper long enough to wrap around and fit into the slot. The sandpaper strip has to be inserted and glued into the groove. Once the glue has set, gle the rest of the paper around the new “drum” and let it set to dry.
Cut off the strip just a fraction before the groove. Use spring clamps or something similar to hold the sandpaper in place until the glue has set. You can start with 80 grit sandpaper and remember all around sanding is 120 grit.
There are two methods to sanding with the drum sander. You can simulate oscilating by holding the piece of lumber with one hand and turn the spindle wheel, moving the drill chuck up and down. Or you can just leave it be as it spins, sanding the piece that you are trying to get smooth. It is probably safer to keep both hands on the workpiece, so remember, follow these directions at your own risk!
