Abstract
This report describes the results of a mill test investigating the effect of a 15 degree alternate top bevel (ATB) tooth for bandsaws. The test involved comparing the sawing variation and surface roughness of Douglas-fir lumber cut by both ATB and standard saws. The test results showed no improvement in sawing accuracy with the ATB blades. In fact, as the blades became dull, the sawing accuracy of the ATB saws deteriorated faster than for the standard blades. Visual evaluation of surface roughness also indicated that the ATB saws produce slightly rougher lumber. However, this may be due to increased tooth bite associated with the ATB teeth. Further testing will be required to determine if the results of this test are truly representative of the performance of ATB bandsaws in general.

Abstract
Standard tooth designs for ripsaws carry a cutting edge which is square in relation to the saw blade axis. This saw tooth design proved to be satisfactory in the past when saws were heavy in kerf and sawdust was not considered as an important fibre source for pulp or other fibre based products. Forintek recognized that this tooth design is not optimum for achieving the best sawing performance and producing high quality sawdust for pulp. This report describes the results of extensive sawing experiments carried out in both the laboratory and in the sawmill to develop a new tooth design.
