| Contd. -2- R4/G21819. (4) Neatsfoot Oil - for treating belting and other leather. I understand that you are continuing to use for the lubricating of the genral machinery of the Works, an oil with a good mineral base combined with about 20% of lard oil, and that such a combination might be made without fear of separating out. The Experimental Dept. should determine whether such an oil will give satisfactory results on the machinery of the Works in as much as it prevents undue wear and undue friction through too high a viscosity. The oil should be compounded and delivered by some firm that we can trust for honesty, such as Price's or the Dee Oil Co. Have nothing whatever to do with the usual oil merchant who employs a crowd of touts to sell at expensive rates an inferior article. Endeavour to obtain and get installed, a practical machine for the testing of the load carrying capacity of a good variety of oils, which I believe will be found to vary immensely. It should be tested at several high temperatures for its practical lubricating properties and for its friction due to viscosity. R.{Sir Henry Royce} | ||
