Miniature Detail Sander for less than $5

[Kazzer]

This has to be a modelers dream! I am currently doing a project where I need a tiny sander to get into those really awkward places

So take a peep at this video and see how a battery operated toothbrush fills this niche.

my contribution to this idea is to take the batteries out and hard wire a low voltage a/c adapter to the brush.
