We have experienced trouble with broken or loose servo friction discs on the B.V. servo and have been in communication with the Tubular & Biforcated Rivet Co. of Aylesbury and their Mr. Izzard inspected the machine in the Works which he states requires a new anvil which they should supply. The trouble in one case was mainly due to the wrong size of rivet and hole and not entirely to the machine. Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems} | ||
