A lumberjack buzzes the competition during the semifinals of the Hot Saw contest.

Extremely loud and lasting no more than 10 seconds, the hot saw competition features 10 competitors using modified engines on their chainsaws in an attempt to make the fastest three cuts in a 20-inch log.

Power, control and precision all play an equal part in posting a strong time in the hot saw competition. These modified chainsaws can weigh up to 80 pounds apiece and rev at extremely high rpms. If you've got the power to hoist the saw, you now need to control the saw well enough to cut three complete discs of wood from a log.
