I needed a small sanding spindle to sand the small corners of a project I’m working on. My store bought sanding spindle is too big and I didn’t want to go out and buy one, plus even the smallest one in the store is too big.
[Above] I found a 4 inch long piece of aluminum rod. It’s a little bigger in diameter than 1/4 inch. I used a hack saw to cut a slot down its lengthy about 1-1/2 inches long.
[Above] I cut a piece of sandpaper about 2 inches long to fit in the slot. You may need to fold over the edge that fits in the slot. Make sure it’s facing the right direction for the rotation of your drill.
[Above] I used it in my drill press. Even though I’m pressing on it, I’m not seeing the aluminum shaft bend. You’ll likely need to change the sand paper often, but this is a good use for the small scraps that some of us accumulate.
[Above] The sandpaper will stand out from the shaft when at rest, but the pressure of what you’re sanding will keep it tight.
