The key item to remember here is the use of the small Dremel sanding drums (sans sanding sleeve) as rotary drivers for small mechanisms. Winding fishing line or twine or wire onto spools is another possible use. Using an electric screwdriver keeps the speed slow enough to make it manageable to hand-hold rather than needing to build a winding jig.

The small chuck shown in the photo could easily be replaced by a bit of 1/4" hex stock drilled to accept the sanding drum and fitted with a setscrew to retain it.
