Another fine and well appreciated product teardown Duck! Any way to attach a motor to that and get a mini belt sander?

Currently I just use small sticks (popsicle or tongue depressors), lay them side by side and slap on some PSA grit to the lot. I then separate them with exacto knife cuts between the sticks.
Shop floor and benches are littered with them but one is always lurking near by. Handy items those mini sanding sticks (either metric or imperial!)
