Power saws

A table saw comprising:

• a table with an opening;
• a blade configured to extend through the opening;
• a motor to drive the blade;
• an elevation mechanism to raise and lower the blade relative to the table, where the elevation mechanism includes a handwheel that is rotated to raise and lower the blade;
• and
• a tilt mechanism to tilt the blade relative to the table, where the tilt mechanism includes a grip plate associated with the handwheel, and where the grip plate is moved in a first motion to tilt the blade in a macro adjustment, and where the grip plate is moved in a second motion to tilt the blade in a micro adjustment.

A table saw comprising:

• a table with an opening;
• a blade configured to extend through the opening;
• a motor to drive the blade;
• and
• an elevation mechanism to raise and lower the blade relative to the table, where the elevation mechanism includes a handwheel that is rotatable to raise and lower the blade, where the handwheel connects to a rotatable shaft, where the rotatable shaft connects to universal joint assembly, where the universal joint assembly connects to a threaded shaft, where an elevation carriage rides on the threaded shaft and supports the blade, and where rotation of the handwheel rotates the rotatable shaft, which rotates the universal joint assembly, which turns the threaded shaft to raise and lower the elevation carriage and blade relative to the table.

A table saw comprising:

• a table having an opening;
• a substantially planar, circular blade configured to extend at least partially above the table through the opening;
• a motor to spin the blade;
• an insert configured to fit within the opening, where the insert has a front end and a rear end;
• and
• a rigid member extending from the front end to the rear end of the insert.
