because there are too many chances for errors to creep 

 into a manufacturing operation when hit-or-miss methods 

 are employed. 



So with the question of glue; the manufacturer should 

 proceed to find out what he needs, Snd then proceed to 

 get it. He ought to buy on specification, just as a man 

 who is building a dam against which so many thousand 

 tons of water pressure are to be exerted, buys the cement 

 and steel for it on specification. It is possible to compute 

 just how much water pressure the dam must resist, and just 

 what weight of material and what reinforcing must be 

 employed to make the structure safe. Consequently, engi- 

 neering methods demand that these computations be 

 made, and the results applied to the job, for it is realized 

 that no matter how experienced or ho^v practical the con- 

 tractor doing the work may be, he may happen to make a 

 mistake. The figures are not always conclusive, because 

 of the possibility of unknown factors developing; but they 

 at least make use of all the information it is possible to get 

 hold of, and eliminate the element of doubt to as large an 

 extent as it is possible to eliminate it. 



Why shouldn't the same method be employed with 

 reference to building a glued-up panel? Why should the 

 senses be relied upon to determine what glue to use, how 

 it should be prepared, to what temperature it should be 

 heated and the various other features that enter into the 

 proposition? Why should not there be a laboratory test 

 to determine these factors, and accurate equipment for 

 the purpose of measuring the results of such tests? 



Some plants have the necessary facilities for testing 

 their glue, and they seldom have any complaints from 

 their customers regarding the failure of their products to 

 hold together. They know what they want, and they 

 proceed to get it. They find out the degree of viscosity 

 and the amount of tensile strength possessed by their 

 material, and they mix it with water in a proportion de- 

 termined by these elements. When they heat the glue, 

 they have thermometers on the kettles, and thermostatic 

 devices v^rhich prevent it from being heated to such a point 

 as to produce a destructive effect on the glue fibers. The 

 material is right, its preparation is safeguarded, and it is 

 spread upon the wood under conditions which, bar acci- 

 dent, will make for good work. 



The head of a successful panel concern, who has en- 

 larged his plant twice in the past few years, and is now 

 trying to buy more machinery w^ith which to increase his 

 capacity still further, said recently that taking care of the 

 glue question has solved many a problem in his factory. 

 Glue is too important a feature of successful manu- 

 facture of built-up products to neglect," he said. "Further- 

 more, it s a penny-wise and pound-foolish policy to try 

 to save money by buying the cheapest glue that is offered. 

 Glue must be right in order to justify my confidence in it. 

 1 have laboratory equipment and believe in laboratory 

 tests; and 1 test every barrel in every carload of glue I 

 buy. In other words, I don't believe in taking a chance 

 if I can help it, and I usually can.
