CANADA LUMBERMAN Why 255 Waterous Band Mills Have Been Purchased No. 3 Guides. Waterous Double Cutting Upper Guide The successful operation of any Band Mill depends primarily on the design and con- struction of the guides. After several years of experience based on the observation of the behavior of the saw under all conditions, we came to the conclusion that the guides must not only be absolutely rigid, but must be made to swing about the exact centre of the saw. The upper guide is arranged for single and double cutting, is adjustable both vertically and horizontally, is fitted with quick opening device, and is water cooled and non-break- able. It swings about the exact centre of the saw blade. This latter feature successfully overcomes any tendency for the saw to cut into or out of the log, and allows the change in the direction of the saw blade on either edge of the saw to be easily and quickly made. In accomplishing this our upper guide has the further ad- vantage that it does not drag the saw out of line, as in other forms, but simply twists it about the centre of the blade. At the same time the exceptionally rigid construction of the guide proper, and the weight and strength of the supporting arm and the vertical slide, keep the saw always in a straight line and permit the mill to cut to capacity and to turn out perfect lumber without difficulty.
