MAXWELL |SACAR
 THAT'S BUILT FINE
Great Accuracy Is Attained in Building of This Little
 Automobile

-The Maxwell is a car built one thousandth of an nich fine said A. NJ. Bailey, of the Motor Sales Corpora ton, who recently visited the great. plant at Detroit. The word fine has many meanings, but applied to a car it may mean that the car looks fine or it may mean the car is built fine. The public usually makes up it's mind about the former and hears lit- tie about the latter. It is no mere claim that the Mexwell is built to very fine limits. It is the actual standard specified by the engineering depart ment by which all of the thousands of component parts of the car are Judged before they are allowed to en- ter production.
 .'The most expensive and modern machinery and the most scientific methods of production are not alone responsible for the accuracy attained tr the manufacture of the Maxwell. The workmen and inspectors play an important part as they maintain a. standard of their own which is not governed by micrometers or delicate gauges. No part ever gets by them that they would not want in their own car. It is the spirit combined with the latest manufacturing facilities that makes it possible to maintain such a high standard.
 Another factor in the production of the Maxwell which makes it pos sible .for the company to control ab- solutely it's own standards is the fact that practically all of the important parts of the car are made in Max well factories. This is a big advantage over most concerns who have to de- pend upon outside companies to pro ! cue the vital parts of their car.
 .The rear axle Is made almost en- tirely at the Oakland avenue plant, any part of which can be interchanged with any other like part and it will fit exactly. The ring gear or drive gear. which is probably the most im- portant part of the axle, takes 3l op- erations, not including the various in- spections before it can qualify as one. ene-thousandth of an inch fine.
 ''The inspection of the gears is per- haps the most important part of the work in the machine shops Gauges from Switzerland are used for this purpose. The tool and inspection de- partments carefully set these instru- ments to the desired point and then seal them with wax so that no work man can change or disturb them. If the gears pass this inspection and there is still any question about them, they are taken to the silent room for he final inspection.
 @The silent room is, as its name implies built of heavy timber, heavy felt and paper lining, so that all sound is excluded. The gears are set on bevel gear test machines meshed with a master pinio,n and the power applied. 4 cotton b6ake Is attached so that the greatest possible strain is placed on the gears during the test. If the gears work silently and pass gear tooth vernier which tests to the prescribed one one thousadth of an inch, the gears are passed on to the heat treatment.
 ''After a part has passed through tho carbonizing furnaces, it is chilled and then relocated until case hardened, and again heated so that the core acquires the proper toughened fiber. Pre- heaters and moten lead vats are used to attain the various heats specified.
 sThe heat in the larger oil furnaces is regulated carefully by pyrometer The heat in the furnace creates an electric current between two wires of different metal The resistance thus created is measured by meter grad uated into degrees of fahrenheit. It is possible by this system to ascer- tain the heat of any furnace at any time.
