Description: |
| Invention is intended to reduce blade breakage by only tensioning that part of the blade that is cutting wood. An additional advantage of the design is that the blade can be twisted to produce a curved cut. Rather than powering one of the wheels to drive the blade, a second band below the table is wrapped around part of the circumference of the lower wheel, with the blade sandwiched in between. That second band—which is subject to a sharp bend as it passes around a small pulley below the table—would presumably be made of leather or some other material that is not subject to stress cracking. |
