2. Preparations – Timberjig Wooden Aids Sawing with the Timberjig requires certain preparations. Building a straight, wooden guide rail. The idea behind the Timberjig design was to create a fully functioning sawmill at a reasonable price. As the basic unit of the Big Mill System, the Timberjig is designed to be easily expanded and work together withother components. Make a straight guide rail out of two, preferably planed, boards, ca 22 mm thick (1 inch) and 120-150 mm wide (5-6 inches). The guide rail should be 40 cm longer than the logs you plan to saw. Do not make the guide rail longer than...

Big Mill System-12

The Work Site – Wooden Aids Sawing – Wooden Aids Prepare your work site on a clear and level ground. The easiest way to support a log that you are about to saw is to place it across two parallel, smooth, and level logs. The height of your support logs should not exceed 50 cm (20 inches). If logs are used as a work bench, remember to keep them from rolling by using e.g. wedges. Make sure you do not saw on an upward slope. It is better that the log bed is somewhat higher on the side you start sawing on, in order to ensure that you saw slightly downwards. Screw a 30 mm (1 1/8 inch) wood block on...

7. Fasten the log securely, paying special attention that it will not move when the Timberjig is mounted on the guide rail. This is a prerequisite for smooth and safe sawing. One method is to screw a board into the log end, making sure that it makes contact with the ground. Tip risk. Check that the log is fastened well. Use at least two wood screws, 4x80 mm (1/4”x3 1/8”) or larger. An alternative is a log clamp (art. no. 4900-001-0400) for fastening the log. Setting the wooden guide rail. Do not start your chainsaw until you have read and understood both the chainsaw and the Timberjig manual....
