This 6’5" track extension is designed to be used with the HM126 portable sawmill. It can be easily bolted to the existing track and extends the cutting capability by 6’5" (1.95m). For instance, when an extra track extension is added to the HM126 sawmill, it can mill logs up to 16’11” (5.1m) in length. If needed, multiple track extensions can be added to the portable sawmill to increase the cutting length beyond 16’11” (5.1m). The track extension is made of 1/4" (6mm) thick 2.5" x 4" (63mm x 101mm) “L” channel that is cross supported with heavy-duty 3" x 6" (76mm x 152mm) rectangle channels. These cross supports ensure that the weight of the log is evenly distributed over a large bearing surface, avoiding any indentations on the log. Additionally, the heavy-duty cross supports provide extra rigidity to the track system. The track extension also includes an adjustable log clamp that securely holds the log in place during milling.
