| The centre pillars are of wood covered with pressed steel. For the screen pillars and front door framing the body pressing is backed with channel section steel, bossed where necessary to take the hinge screws etc. The screen rail is stiffened with a two-inch channel section pressing, webbed at the pillar corners. To this the metal instrument board is bolted. DOORS. These are made up of two steel pressings with welded joints, the rear panel being cut away to permit window and lock fittings to be passed up into position. Door panels are sprayed inside with tar to damp door vibration. Upholstery is held in position with spring wire clips which press into holes round the door frame. Steel hinges are used with steel hinge pins, on the top of which a lubricator is fitted. The method of holding the hinge in position is very good, the holes being tapped and long steel screws used. Doors are held in position by dovetail door stops. There are two of these on each of the front doors, fixed to top and side. Rear doors have only one dovetail stop. Rubber buffers are let into the pillars top and bottom. The front door weight, excluding detachable ventilator window, is 55.75 lbs. This is 15% lighter than a corresponding door off a 25 HP: body. Weight of ventilator window only = 2.75 lbs. A photograph of the dismantled door is attached. Although the doors are rattle free, the sound when closing them is too metallic. The doors on the Buick 8 which have a wooden framework give a much more pleasing note. See attached photograph. MUDGUARDS. As previously mentioned, the wings, running boards and valances are all bolted together and the running board valance in turn is screwed to the underside of the body, making everything very rigid. No wood screws are used in mounting mudguards, 5/16" cadmium plated steel screws with large washers being preferred. | ||
