Why YOU Should 

 Use Disston Saws 



A Few of the Reasons for Disston's 

 80 Years' of Leadership. 



D 



ISSTON Saws are manufactured 

 completely in the Disston factory. 



DISSTON workers are, for the most 

 part, expert craftsmen. A great 

 many of them have grown up in 

 many cases have followed their fathers 

 in the Disston factory and are truly 

 experts in saw-making. Eighty men in 

 the Disston factory have worked here 

 more than 40 years! 



THE steel used is made in the Diss- 

 ton Works within the factory 

 wall because to insure constant 

 good quality, it is necessary to control 

 absolutely the quality of all steel used. 



YOU have undoubtedly heard of 

 Disston-made Saw Steel. It is 

 known for its good quality where 

 ever saws are used. This is because it 

 is made from a Disston formula which 

 many years of experimenting have 

 shown gives the best saw steel. 



DISSTON Saws are uniformly and 

 properly hardened and tempered. 

 The processes by which this is done 

 were developed by Disston and are used 

 exclusively by Disston. 



DISSTON Saws are ground by a spe- 

 cial method which gives a thick- 

 ness and taper to the saws that is 

 exceptionally accurate and uniform. 



THESE are some of the reasons why 

 every Disston Saw is a good saw. 

 They are also reasons why so many 

 users have found that it pays to specify 

 "Disston."

Let Us Send You 

 The Crucible 



T^rlE House of Disston publishes a 

 * monthly magazine. Did you know 

 that? This magazine, "The Crucible," 

 is a magazine for lumbermen. 



It contains stories of successful lumber- 

 men in all parts of the country. It car- 

 ries write-ups of interesting operations. 

 It often has an article on some special 

 phase of saw sharpening or repairing. 

 There is a page of jokes which is the 

 equal of any. 



We will send you this magazine free of 

 charge if you would care for it. All 

 you have to do is ask for it. Drop us a 

 post card with your name and address 

 on it and say, "Please put my name on 

 the Crucible Mailing List." Do it to- 

 day you'll like it. 



Things Not to Do in 



Operating a Saw 



THE following is a list of 

 "don'ts" for the saw operator 

 that are taken from the "Disston 

 Lumberman's Hand Book." Many 

 readers have told us that a list of 

 this kind was a time-saver for them 

 and we print it here in the hope 

 that it will be of value. 



DON'T USE 



power to maintain regular 



Insufficient 

 speed. 



Too thin a saw for the class of work re- 

 quired. 



Too few or too many teeth for the 

 amount of feed carried. 



Weak or imperfect collars. 



Collars not large enough in diameter. 



Ill-fitting mandrel and pin holes. 



Uneven setting and filing. 



Points of Teeth filed with a "leal" not 

 square across. 



Too little set for proper clearance. 



Too much pitch or hook of teeth. 



Irregular and shallow gullets. 



A saw out of round and consequently 

 out of balance. 



A sprung mandrel, or allow lost motion 

 in mandrel boxes. 



A carriage track neither level nor 

 straight. 



A carriage not properly aligned with 

 saw. 



A journal which heats. 



Guide-pins too tight or not properly ad- 

 justed. 



Teeth which have backs too high for 

 clearance. 



Any saw too long without sharpening. 



SPEED! 



"Near Stevens Point, Wisconsin, on 

 September 19th, 1920, two men using a 

 Disston High-Grade Cross-Cut Saw 

 rut tht-oueh fl Grf^y Elm log, 18^^ inches 

 in diameter in 15 seconds." 



Y^E do not hold up this example of fast 

 cutting as a record. It is just one 

 instance that we know of and may not 

 be a record accomplishment. But it does 

 illustrate what our statement that the 

 combination of the famous Disston-made 

 Steel, Disston manufacturing methods, 

 the latest improvements in cross-cut 

 saw design, and Disston workmanship 

 (developed through 81 years of experi- 

 ence) means to users of cross-cut saws.
