| -S- Ha/Rm.{William Robotham - Chief Engineer}2/KW.19.2.34. Further to my previous note - (1) Oy. uses 3" clearance to rubber buffer and then low rating buffer allowing 1" movement before coming solid. (2) He still wants 4" re-bound. (3) Out of centre point 2-3/16" not 2" as I originally stated. (4) Damper loads ≠ 50 lbs. in the min. position. (5) All adjustment is made on the valve, none on the inertia weight. (6) For trying various ratios of k²/ab G.M. have been running a car fitted out as below :- [Diagram of a car chassis showing Center of Gravity (C of G) and weights (Wts) at the front and rear] The car is sprung for say 10 weights in addition to the body at the C. of G.{Mr Griffiths - Chief Accountant / Mr Gnapp} By transferring these weights in pairs, one to front and one to the back, k²/ab can be made equal to one without altering the initial spring deflection. (7) Cadillac steering 20-1 middle 18-1 locks. Ha/Rm.{William Robotham - Chief Engineer} | ||
