Further to my previous note
①. Dy{F R Danby} uses 3" clearance to rubber buffer and then low rating buffer allowing 1" movement before coming solid
②. He still wants 4" rebound.
③. Out of centre point - 2 3/16" not 2 ½" as I originally stated
④. Damper loads - F -> 50lbs in the min position
⑤. All adjustment is made on the valve, none on the lever inertia weight
⑥. For trying various ratios of K^2 G.M. have been running a AB car fitted out as below.
The Car is sprung for say 10 wts in addition to the body at the Cg & x. By transferring these wts in pairs, one to front & one to the back, K^2 can be made equal to one without altering the initial spring deflection.
⑦. Cadillac Steering. 20+ middle vs{J. Vickers} -1 locks
