You can't even aim good enough to determine the weight differences! Let us know how it goes. Weights are made of iron or brass; brass is used for smaller weights and hangers for testing up to up to around 1000g and have a 4.5mm rod and slots to suit. This document specifies possible manufacturing tolerances for plastic moulded parts. In general it is possible to achieve 0,1-0,4% weight variation using scientific molding. wall thickness and weight. You need to provide the linearity, repeatability, and off axis specifications in order to know the tolerance of your balance.
