摘要： An adjustable miter gauge for use with a table saw includes a miter attachment and an adjustable guide bar coupled to the miter attachment. The miter attachment rests on a working surface of the table saw. The guide bar is received in a slot in the working surface. The guide bar includes a main body, which has first and second surfaces parallel to side walls of the slot, an adjustable body, which has a third surface parallel to the first surface, and a deformable biasing member. The adjustable body is coupled to the main body and slidable between a first position, wherein the second and third edge surfaces are coplanar, and a second position, wherein the second and third edge surfaces are not coplanar. The biasing member is arranged between the main body and the adjustable body and biases the adjustable body toward the second position.

摘要： A power equipment includes a base defining an enclosure space, a table supported on the base, and a cutting assembly supported within the enclosure space below the table. The cutting assembly includes a motor having an output shaft and a dual stage drive system operably coupled to the output shaft. The output shaft defines a first axis of rotation. The dual stage drive system includes two drive stages which enable the motor of the drive system to be moved farther inward, away from the table top, which provides clearance for the incorporation of other features into and immediately below the table top.

摘要： A table saw includes a base assembly, a table assembly supported by the base assembly, and a saw assembly supported by the base assembly. The saw assembly has a motor having a motor output shaft and a power train assembly. The motor is configured to rotate the motor output shaft at a first rotational speed. The power train assembly includes an intermediate shaft, a first gear stage, an arbor shaft, and a second gear stage. The first gear stage is configured to transmit rotation of the motor output shaft at the first rotational speed to rotation of the intermediate shaft at a second rotational speed, which is less than the first rotational speed. The second gear stage is configured to transmit rotation of the intermediate shaft at the second rotational speed to rotation of the arbor shaft at a third rotational speed, which is greater than the second rotational speed.
