I made my own stiring tool with a "c" cell battery holder, small electric motor and apush button switch all from radio shack. A brass sleeve, a bent paper clip, and lot's of epoxy gave me a very ugly but useful tool.
For shaking paints, I use zinc plated steel BB's. These can be left in the jar for enamals, but should be removed right away for any water based paint-they will rust. How to remove them from the bottle? Remember I specified STEEL BB's? When done shaking, place a good magnet against the top of the bottle before turning right side up and Bingo! There are the BB's once you unscrew the cap!
