John's method sounds legit to me, it'd prob be best to have a pan hanging from a cable (steal one from local supermarket produce section) or something looped over the wrench so you could ensure the center of the weight was at x distance on the handle. You'd probably be able to test the higher end of the scale that way rather than trying to balance 100lbs on top of the handle or having a kid stand on it.
