| Contd:- -2- V4244 Hal/LG12.1.22. CLUTCH. We have tried some of the experiments instructed for the clutch. We have not found anything better than the standard clutch with Ferodo bonded asbestos in place of the Ferobestos which was in the first clutches. With the bonded asbestos we do not have the fault of the clutch slipping when hot and we can use weaker springs in the clutch. We have very little fault to find with the standard clutch. We have some further experiments still to test. HR. RECEIVED | ||
