| Contd. -2- AC.7 11.3.24. It would be difficult to use control brushes of only .125" thickness, on account of their fragility; but it may be possible to use brushes of .2" thickness, which is that of the present standard control brush, all round, thus simplifying the provision of brush parts. The virtual thickness of the thinner brushes which were tried was .2". EFC/RJA. | ||
