| Wor{Arthur Wormald - General Works Manager}/Hy{Tom Haldenby - Plant Engineer}20/L25214. Sheet. 2 shock directly to the frame and in the other case the shock to the frame is reduced by being partly absorbed in the steering joints and levers. The flanges of the small cross member both of which are broken seem rather thin, being only .150" thick. The bracket which carries the rear spring bearing is supported on this cross member and I should say that it was the upward blow from the humps which broke the flanges. The frame brackets F4273 which are the new brackets with square base and 4 bolts for carrying the front end of the rear springs are not damaged and seem to behave alright so far, but the test has not run long enough to give a definite opinion on them. I would like to see a bigger base on this bracket, also more bolts. Why not make a large circular base with say six bolts ? I think this could be arranged and so do away with having to cut away bits from the inside of the base to clear bolt heads. I think it advisable also to thicken up the flanges of the large tubular cross members as they seem very thin for the size and strength of the tube. | ||
