| Visit to Coachbuilders with Mr Oldham 10th & 11th inst re door rattles etc. - The Chief questions and answers are shown below. - Annotations: ①, 8/25 meeting, X393 TABLE: Column Headers: 1. (Coachbuilder) 2. Only one side door each side in double limousines? 3. Only 4 points for body to Rest upon? 4. only face fit for doors? 5. Matchboxing? 6. Oval doors? 7. Dovetails? Row 1: Barkers - Yes, This will minimise door rattles. - NO, Could possibly manage with 6 points if weight of runners etc is increased by the addition of steel plates etc. - No, Could not keep water-tight. - Doorways do not hinge at corners so much as the pillars & roof bend. Fit of dovetail dowel-plate important. - No, but small radius can be arranged. - Yes. Must be very good. One not two. Row 2: Thrupp & Maberly - Yes. - Thinks it might be done if 4 points are at 4 corners of body, not under door pillars. The twist of frame will then twist body & cause noise. Prefer 6 points & increased weight of body. - NO - Corners do not go much door pillars bend. Roof also bends. Have invented Spring dovetail dowel-plate which has cured door rattles. - NO - Must be very good. New Spring dovetails are an improvement. | ||
