Another Edition of A WELL-KNOWN cornmerthe Babes in the 1-1cial-vehicle manufacturer
Wood who has had returned to him
by the Government a number of lorries for overhaul and redistribution was rather surprised at the condition of some of them. In one instance a vehicle was, at first, thought to be without an engine, but, upon further investigation, the unit was discovered in the back of the lorry, where it had been completely covered with leaves, reminiscent of the story of the Babes in the Wood. Exchequer Encourages WHEN a member of the Membership of Trade " industry, either on the pro., Associations . . . . duction or operating side, is considering the question of whether or not to join an association, there is a particularly important point to remember. Contributions to legitimate trade associations are allowable as expenses under the provisions of the income tax and excess profits tax. This is a wise provision of the Exchequer, which encourages co-operation between individual concerns and exchange of experiences.. Blitz Buggy Makes nNE of the most useful motor ks Appearance in •--• vehicles in the American Britain Army, in the opinion of its
leaders, is the "Blitz Buggy" or "Jeep." This is a stubby cross-breed between a . staff car and an armoured motorcycle and sidecar, and is rather an ugly mongrel, but this does not matter for war purposes, it being performance that counts. According to one American expert, this vehicle has stepped up the American Army's transport facilities by 50 per cent. It has a wheelbase of only 6 ft. 8 ins., compared with the 9 ft. 4 ins, of the Ford V-8 there. With a 42 b.h.p. engine and fourwheel drive, it provides powerful traction, being able to haul light field guns, carry six fully equipped men, weapons such as machine-guns, anti-tank guns, mortars, etc., and can serve as a radio car. It has been successfully carried by aeroplane, and experiments are to be made in dropping it by parachute. The U.S. Army has some 5,000 in service, and has ordered another 16,000 from the Ford concern and other wellknown makers. This type of vehicle has been tried out in Britain and is already in use in Africa.
Practical Hints on THIN-WALLED tubing
useful booklet, issued by Henry .
Wiggin and Co., Ltd., Grosvenor House, Park Lane, London, yv.i, on the fabrication of monel, nickel and other seamless tubes gives useful tips on this and many other points. The use of lead as filling is not recommended; suitable fillers for nickel-alloy tubes are resin and Cerrobend. Wood plugs retain the molten resin and gaps should be filled as the material solidifies. After bending, it can be melted by torches and run out. Cerrobend supplied by Mining and Chemical Products, Ltd., Manfield House, Strand, London, W.C.2, is, however, preferable. It melts at below the boiling point of water, and is poured into tubing already filled with hot water (poured from the top of the melting ladle), thus displacing the water. When filled with alloy, the tube is plunged quickly, corked-end first, into cold water, ensuring a fine crystalline structure in the alloy which renders it-ductile. Before bending, the tube should be allowed to attain room temperature. Melting-out is by steam, water or air.
