| 579 PRODUCTION LINES Metal Specials Went through one of the biggest body hardware plants in this industry the other day. It's a revelation to see how they handle the production of sheet metal parts such as garnish molding, window trim, and the like. The operations are so different from what we see in an automobile plant that they're doubly interesting. Have you seen wood graining in real mass production—"smoking" finish over the grain by dextrous girls armed with air guns? Then the bending of window frame and reveals on ingenious machines that have never been pictured elsewhere. We are quite excited over this operation and may be able to tell you much more about it very soon. All That Glitters All that's black is not graphite. That's the burden of the discussion in Technical Bulletin 40.1, recently issued by Acheson Colloids. If you are interested in engine lubrication by all means read what they have to say about sludges and contamination. The important thing is—don't conclude that sludge is graphite because it is black. Splits Hairs Not the least of the advantages of being billeted in Detroit, as we will be from now on, is the privilege of attending the Ford Sunday night concerts. You get an entirely different picture when you see the thing first hand. W. J.{Mr Johnson W.M.} Cameron's talk last Sunday had to do with the work of C. E.{Mr Elliott - Chief Engineer} Johansson, master of scientific measurement, who was there in person. This reminded us of our visit to the Ford plant some years back and our amazement at finding Jo-blocks used right in the shop. Each operator was provided with a set of blocks specifically required at his station. This was the first time that these valuable gages had been used in anything but a master checking device. Supercharging If the signs point rightly we may expect to find a general spread of supercharging for passenger car and heavy-duty engines. Some engineers feel that heavy-duty engines, at least, are about as big as they can be and that increased power and performance must come through supercharging rather than increased size. One organization out here is taking the thing very seriously. They have started a research project designed to study supercharger design and expect to develop some fundamental information concerning engine performance through supercharging. For the Factory Tool engineers and maintenance men will be interested in a practical handbook just issued by Landis Machine Co. It's the fifth edition of the well-known treatise on Landis threading and tapping equipment. How to grind chasers, how to set chasers, operation, cleaning and repairing heads, special threads—these are just a few of the practical problems that are discussed in detail. Seems to us that this handbook is made to order for you. Ask us for a copy. Down to Three We hear that a new two-cycle aircraft engine has gone through its paces at the Dept. of Commerce. In the absence of actual details of design, what interests us most is the fact that this job is supposed to sell at $3 per horsepower. Isn't that something. Doesn't Grow Exhaust manifolds of NiResist have been rather popular lately on quite a number of heavy-duty engines. It must be a comfort to know that you can get a material relatively free of any tendency to grow and one which is free of permanent effects of high temperatures. Its higher coefficient of expansion is taken care of by using special expansion joints. By Compression Some of the gear failures which have occurred in highly stressed gear trains are attributed in some quarters to inordinately high compressive strains. The usual Lewis formula doesn't mean a thing under these conditions. Most of the recent investigation has been based upon the use of Jandesek's formula, which takes into account the changes in load-bearing area under heavy loads. Cleenie Plug AC has taken its old plug off the billboard, put it on wheels, and there you have either a desk ornament for yourself or a toy for the kids. Our little souvenir goes home. Did you get one—if not tell us about it. —J.{Mr Johnson W.M.} G.{Mr Griffiths - Chief Accountant / Mr Gnapp} Automotive Industries MANUFACTURING MANAGEMENT METALLURGY | ||
