Set up the hanging digital fish scale purchased from eBay. 25 pounds capacity, accurate to within +/- 0.02 pounds.
Begin hanging objects. Weights are all over the fucking place. 2 pound CO2 tank? Well lessee that evidently weighs 0.14 pounds! Media alert, laws of physics repealed in Valgard’s garage! Hang various things of known weights and my golly gracious, sometimes you almost get a weight within the realm of possiblity. Error weighing a can of beans is no big deal, error when measuring out super compressed gas can result in blown valves and browning of shorts.
Piece of crap. Off to the fishing store to get a proper hanging scale.
