I am thinking about fabricating a bicycle trailer for my commuter bike and
would like and ideas everyone might have for design and materials. Some of
the design goals/criteria that I would like to incorporate into the trailer
that makes the design difficult...

lightweight
aerodynamic
secure-lockable compartment~2-3 cu. ft.

I was thinking about using a large S.S. sald bowl for the 'nosecone' and
tail-end and weld both to a galv. sheetmetal cylinder. This would be the
main storage compartment. I am having trouble with the best method for a
hatch and lock; any ideas? Even crazy ones? thanks, rick
