| -2- Contd. It should be remembered that our range of 58º is rather difficult to produce satisfactorily electrically - in fact several makers will not attempt it. In regard to the electrical principles, we are going into this matter thoroughly and have in preparation a report and some conclusions which we are also proposing to send to Messrs. North. We agree with your recommendation of the bakelite wheel and steel pinion and that the Watford make and break is better than previously. It has been very difficult to get them to make continuous cams, but they have done so at last and we have four further machines so fitted for test. For reasons stated earlier in this note, we think we as a firm are relatively rather exacting, though we do not think we have confused Messrs. North. We do not see any reason for supposing that Watfords have become more inefficient than previously - it has always been very difficult to get them to follow our recommendations. Another report was in preparation when your RL/M16.4.28 arrived, dealing with the various possibilities of other makes. EFC. | ||
