Abstract :
Mr. J. Ronald (Section President, who presided) thanked Mr. Park for a very interesting lecture. Mr. Bamford stated that during the exhibition of the lantern slides, several of the gauging devices had appeared to be mounted on somewhat flimsy types of tables, and he wondered whether the vibration in the machine shops was likely to upset the reading of the dial indicator, and if so, what steps were taken to safeguard this problem?
