| (3) I gathered from Barkers, Hoopers and Thrupp & Mabberley's that the Daimler method of supporting body is not satisfactory, and that Daimler bodies are noisy A - hinge. B - dowel pin sliding up and down in plate on frame C - hard rubber block. The dowel B rattles and squeaks, the relative movement of body and frame is 1/2" here. The rattle and squeak of B has been so objectionable that coach-makers have occasionally threaded B. and fitted nuts. The result of this treatment has been that the body has broken about D.D. Net result of interviews is that coachmakers consider that the bending and whipping of door pillars combined with flexible roofs causes door rattles. The fitting of two dovetail-dowel plates makes matters worse, one perfectly fitting or one adjustable dovetail-dowel improves matters. Bodies built under present weight limits are not strong enough to support themselves especially at rear. To support itself, metal plates or angles should be fitted along the runners, for heavier door pillars and a stronger roof must be used, the | ||
