[Crossed out text: Just a quick note to suggest alterations to some points which have failed.] I find here that spring links and front horn require very close fitting to be silent and on No.4 it has not been wear but closer fitting which we have had to make. I have witness for this, but the area of the surfaces are to be increased and hardened wherever practical. Steering box breakage may possibly be writhing of the frame, have not seen break but suggest (1) making casting heavier, (2) reinforcing with wrought steel hoops - round bearings, (3) making the broken part as a drop forging in mild steel. Handwritten: X4833 Dynamo. Kindly find out how it was that the brushes I said were to be used on the dynamo were not used, after my sending twice or three times exact instructions that certain "Le Carbon" brushes were to be used, someone fitted Morganite, and even there the wrong type, i.e. high conducting soft copper ones instead of low conducting, hard, pure carbon ones. Those responsible should lose their position; they have cost the Company much trouble, money, and damaged my reputation, showing my confidence in them and my policy wrong. The commutator flying to pieces might be through excessive heat and sparking at the brushes, but I think we ought to make this impossible by using steel rings to reinforce the Bakelite and pass by a steel tube or equivalent, so as to keep the end rings from spreading. [Text next to diagram] possibly broke through here allow this and this to come out end-wise, rather than the end rings bursting by tension, so that like an | ||
