| Progress Meeting No: 17. Page 2. with Works practice. 4. Front Road Springs. - F.4620. Our front road springs are specified of twelve different types to suit the range of loading required for different bodies etc. For these different springs, ten, eleven, twelve, thirteen and fourteen different plates are used, and the Production Dept. pointed out that Messrs. Woodhead often find that a spring when made meets our requirements as regards loading etc., but the number of plates may perhaps be twelve while the number specified by us is eleven. They ask that we shall accept springs that pass the loading tests providing they do not incorporate less than the specified number of plates. The Production Dept. proposed that those springs specified to consist of twelve, thirteen, and fourteen plates respectively, should be accepted providing that they have not less than the number specified or more than 14, and that those springs specified to have ten and eleven plates respectively should be accepted providing they have not less than the number specified nor more than twelve. On the Test Dept's suggestion it was agreed that this practice should also apply to old type springs for the repair shop. 5. Rear Shock Absorber. - Taper Bolt and Nut for Connecting Link Arm. - F7737 and F.7742. The Tool Dept. requested that an undercut might be added between the threaded and taper portions of the bolt. (n It was agreed that the nut should be increased in depth to enable a recess in its base to be used instead of the undercut on the bolt, as it was believed that this was more in accordance with Mr. Royce's wishes. The Tool Dept. agreed that the undercut was not essential providing grinding was not called for. 6. Spring Brackets. - G8820/1. These brackets are made right and left hand, but produced from one set of dies. This necessitates the bosses which have been provided for the Shock Absorber attachment to be machined to the dimensions and shape given on the drawings. The Tool Office who are arranging to profile these bosses, suggest that we could modify the outline as shewn in pencil on the blueprint. It was agreed that the profile should be modified, as its present form was adopted to suit the partial machining operation originally intended. The processing now proposed enables a more normal shape to be adopted. Contd. | ||
