Trot Salt - Carburation} Rm{William Robotham - Chief Engineer}/GB.5/SW.26.6.41. re Ferobestos Pulley for Crankshaft. (Item 24 in Conference Minutes). Ferobestos is easily machined and is much lighter than Aluminium, but it is a poor conductor of heat. When all the pulleys in a triangular drive were made of this material, the belt caught fire. As a preliminary test, we propose to make one of the two pulleys on the Coolant Pump Rig of Ferobestos to see if the lack of conductivity results in undue heating of the belt. Put in car engine damper file if there is one. Rm{William Robotham - Chief Engineer}/GB. G.B. | ||
