Load-Sensitive Column for a Strain-Gauge Load Cell
The column inside Ruge's load cell (1949) carries the whole load and the bonded strain gauges. Its lower end screws into the base; its upper end is rounded to bear in the piston's bore.

Rough-turn to within 0.03–0.04 in of size, then take the finishing cut slowly, with cutting oil. Ruge allows round, square, solid or hollow; a square section (filed or shaped flat) takes the gauges more easily.

Ruge's patent gives the part's shape and job but no material or size. Mild steel and silver-solder brazing are our choice; size it to the load you need. Lathe method after Palmateer, Elementary Machine Shop Practice (1918).
