Opps the URL is:

The second page sounds
a lot like what you're looking for.

Indeed, their "motors page 2"

(more direct URL:
http://bizarrelabs.com/motor2.htm
)

shows what they descrbe as a "classic cub scout motor" and it is
functionally very similar to what I built. It uses nails for the frame
instead of a tin can but otherwise seems extremely similar.
(I certainly remember lotsa scotch tape being part of the
commutator...)

Thanks! I'm sure my kids and I can get one together soon!

Tim.
