With reference to your memo requesting tests to be taken with a lever clipped on to a shaft by means of a biting in bolt. We are preparing to carry out the test but in the meantime we thought you might like to know our experience with this type of joint. We attempted, on the chassis, to fix the brake lever by this means but were forced to use round keys before we could get the lever. firm. There are some levers on the brake equalising shaft which also have biting in bolts; in these we fit taper pins so as to ensure they do not move. We agree that in these cases the levers are fixed to tubes which do not allow the bolt to bite in very far. Wherever we have used this type of joint we have never found it a very great success. The success of the joint relies too much on good fitting. EH. | ||
