5.3 Others VARIABLES WHICH AFFECT BANDSAW BLADE LIFE 1 . The Operator - The operator is the most important variable at any test. He can make or break any test and often has a great deal of influence over whose bandsaw blades are used. He can also be a good source of information on what is going on, competitive situations, relationships with manufacturers or distributors, etc. - Page 23 12. Machine Condition-Whether a machine is old or new, and whether well maintained or not contributes to how well it runs and how long the band last. The better shape a machine is in, the better the bands will run. Poor machines ruin bandsaw blades. 13.
