X. 7230 X. 7005 In France we are waiting for two things - the above, and the engine mounting - i.e. slightly flexible on all four feet. Could this box be cast in heat resisting aluminium? Would it be strong enough not? Naturally if it were cast we need not bring the pipe in radially. The engine will move about XXXX slightly - ought not the stay to be from the engine instead of the frame? Perhaps the pipe could be very near indeed to the bottom flange of the frame. The horizontal pipe is the better flexible connection between the engine and frame. A welded job seems preferable to brazed. In a welding job the pipe need not be radial. It could be tangential to about half the radius. Could the front box be made of two pressings. Spherical. Small radius. Weld short or long pieces of pipe to this front box and make the joints in more convenient place than close to the box. Butt welded or slightly telescoped. It would appear more convenient to stay the front box from the lower half of the crankchamber. contd :- | ||
