84612 BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}3/M17.12.32. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} E.{Mr Elliott - Chief Engineer} 20/25 FRONT AXLE CONTROL. x5420 We have gone into the question of fitting front axle control to existing 20/25 cars to overcome the difficulty when using stiff brake drums, and send herewith N.scheme 3624. It appears to be necessary to retain the plate, but we suggest it might be modified in shape as shewn. It has been necessary to set the shock damper lever, but in other respects the damper is unaltered. We notice that on J.3. the triangle has been considerably stiffened up as compared with the original N.sch. Could we be advised as to the reason for this, as our calculations seem to show an ample margin of strength with the section shewn on this drawing. DA.{Bernard Day - Chassis Design} | ||
