Therefore, it is desired to use smaller diameter drive hubs for blade mounting and thinner blades to be able to saw larger diameter material with smaller diameter saw blades. These criteria however weaken the lateral stiffness of the blade and the blade may vibrate more due to the large diameter / blade thickness ratio.

Like chain saw mills (a chainsaw on a guiding table), they can be used inexpensively by one or two people out in the field. In a full-size sawmill, the blades are mounted on wheels with a diameter large enough not to cause metal fatigue due to flexing when the blade repeatedly changes from a circular to a straight profile.
The saw blades are powered by a 28-horsepower engine and the assembly weighs 830 pounds. This design is used to prune trees for customers such as American Electric Power. Another design, with a single, horizontal, 47-inch, circular saw blade, is used to cut the tops off trees which are at risk of falling across power lines. [1] [2] [3]
