Table saw
Table saws and table saws designed to incorporate safety systems are disclosed. The table saws may include vertical slide elevation mechanisms positioned toward the rear of the saw and constructed so that an arbor block and blade can retract when a safety system detects an unsafe condition. Other table saw parts and components are also disclosed.
1. A table saw comprising:
a table to support a workpiece;
a blade able to extend at least partially through the table to cut a workpiece on the table;
an arbor block adapted to support the blade and pivot downward relative to the table around a pivot axis to retract the blade; and
a drive mechanism to spin the blade, where the drive mechanism includes a motor, a motor pulley, a double pulley, an arbor pulley, a first belt extending around the motor pulley and double pulley, and a second belt extending around the double pulley and arbor pulley, where the double pulley is supported in the saw to rotate around an axis offset from the pivot axis.
2. A table saw comprising:
a table to support a workpiece;
a blade extending at least partially through the table;
where the table and blade are configured so that a workpiece is cut by a user causing the workpiece to move into contact with the blade in a feed direction; and
an elevation mechanism configured to adjust the height of the blade relative to the table, where the elevation mechanism includes a handwheel and handwheel shaft, where the user applies a force to operate the elevation mechanism by turning the handwheel, where turning the handwheel turns the handwheel shaft, where the elevation mechanism further includes a transfer mechanism to transmit the force applied by the user to operate the elevation mechanism from the handwheel shaft to a position generally lateral to the handwheel shaft;
where the transfer shaft is behind the blade relative to the feed direction.
