We realise that a half floating arrangement will always weigh more than a fully floating axle, but think the extra weight (due solely to the larger axle shafts) is worth while to eliminate all slack. The saving in cost will be about £1 per car, due to the absence of splines connected with the wheel drivers. If at any time we should use pressed instead of spoked wheels, this can be done on a half floating axle with a saving in weight of about 12 lbs. It should be possible to retain such a wheel with one central nut. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
