ok, heres some pics of the finished cargo cruiser. i went with alleng's idea of using hemp twine, although i first wraped each lug in pure sisal fiber, as i feel that the twine does not absorb the resin into its core. so the twine is partially esthetic, although i am sure it adds strength to the lug as well.

a closeup of the hemp lugs:

both bikes can now be seen at work on the streets of san cristobal
