Laboratory steelyard
To make a steelyard weighing to 500 g use a wooden lath only one metre long balanced on a strong sewing needle stuck by it 3mm from its upper edge and 12 cm from one end. A disk of lead or anything suitably heavy can be used as counter-weight: if lead is used, a disk of it can be 'cast' in a tin lid.
A wire stirrup carrying a boot polish tin lid serves as scale pan and can be suspended 6 cm from the pivot.
