| With reference to :- (1) Not needed now, was to test if deflections caused cross winding which would be reduced and cut down in width. (2) A slight mistake here. I did not mean to reduce the diameter of the gears. (3) I still think this may be needed. (4) Wait. I will go into this matter further. (5) Arranged with Mr Nadin and Mr Wormald on another sheet. (6) Cancel. Though rigidity of centre in all gearing seems absolutely necessary. (7) Yes. I originally intended so for the sake of testing both axles but rope wheels will be found to be rather heavy, hence the reason of present ones. (8) Yes. (9) Yes. F.H.R. | ||
