| (2) of a buttress tooth are very reasonable but experiments show no advantage, and theory (as far as my knowledge goes) very little and some disadvantage. I look upon this worm gear as scarcely wise to abandon, it is not an urgent matter, and could be experimented with when we can afford the time to make a throughly good worm wheel ourselves; no use getting any more doubtful ones made out and they seem to require to be better or different from than Lanchester, or Daimler supplies for our powerful engine. I will go further into this matter with Mr Bailey. In the meantime complete the best you have got in hand, and let us know how that behaves in practice. The worm gear chassis would be better with the new double road wheel brakes for obvious reasons, too lengthy to explain here. F.H.R. | ||
