Being from a seafaring area I've always been clear on jury rigging but how about jerry-built?
I know it means shabbily done or built to sell but not to last very long... but perhaps you have a different meaning ?
I often hear the two flip-flopped ... and jury-built used instead of jerry-built.
Is it perhaps because jury-rigged sounds more like you have tried to tamper with an empanelled jury?
wow
