Claim:
1. A table saw comprising: a table defining a work surface; a substantially planar, circular blade configured to extend at least partially above the work surface; a motor to spin the blade; an elevation system to change the elevation of the blade relative to the work surface, where the elevation system includes a handwheel adapted to be turned by a user to raise the blade from a fully lowered position where the blade is below the work surface to a fully elevated position with 5 turns or less of the handwheel, where a turn is a 360 degree rotation; and an anti-backdrive mechanism to prevent gravity from causing the blade to drop more than a quarter of an inch when the user releases the handwheel, where the anti-backdrive mechanism operates without the user having to perform any action after releasing the handwheel, where the anti-backdrive mechanism operates automatically without any manipulation from the user.
