A system including a lumber-pickup arm having a plurality of suction cups in a staggered configuration to pick up a piece of lumber that may be cracked, crooked or askew on the pile of lumber from which it is to be picked. In some embodiments, the system performs a method that includes locating a selected piece of lumber to be picked up; lowering the pickup arm so that at least some of the plurality of suction cups are seated on a first surface of the selected piece of lumber; reducing air pressure within the at least some of the plurality of suction cups; raising and moving the pickup arm to move the piece of lumber to a first destination; and increasing air pressure within the at least some of the plurality of suction cups to release the piece of lumber at the first destination Cups not holding vacuum are deactivated.

A workpiece limiting device for power tools includes a support arm adapted to contact with a workpiece and limit the workpiece, and a body. The support arm is supported by the body and movable relative to the latter. The workpiece limiting device further includes a quick-release device. The quick-release device allows manual adjustment of the position of the support arm relative to the body and locks this position without using an external tool. Through the workpiece limiting device, the adjustment range of the position of the support arm relative to the power tool can be greatly expanded, and workpieces in different sizes can be processed.

A power tool stand includes a stand body, a slide rail mounted to the stand body, and a first holder and a second holder coupled to the slide rail and slidable along the slide rail. The first holder and the second holder are adapted to maintain a relative distance between the first holder and the second holder substantially fixed by a locking device. By using the locking device, after fixing one holder, the user can conveniently fix the other holder to the slide rail at a predetermined distance in a fool-proof way.

A multi-purpose tool guide apparatus for use with woodworking and similar applications where the apparatus can be employed as either a stationary guide for applying a biasing force against a workpiece or as a hand-held tool for pushing or controlling a workpiece that us being cut or shaped. The multi-purpose apparatus includes features and components that allow for it to be configured and employed in various configurations.

Extension rails for table saws are disclosed. Some of the disclosed extension rails can be attached to a table saw without a user having to manipulate a lever or knob. Extension rails particularly relevant to portable table saws such as jobsite and bench-top table saws are disclosed, including extension rails that can provide 48 or more of cutting capacity on jobsite and/or bench-top table saws. A method of attaching extension rails to a table saw is disclosed that does not require the use of a tool or the manipulation of a knob or clamp.

A safety system for powered cutting tools includes a miter saw safety device. Embodiments of the miter saw safety device may be positioned on one or both sides of the rotating saw blade and include a pivotable support arm and a support plate that is repositionable relative to the support arm. In some embodiments the support plate is biased toward the guide fence of the miter saw. The device enhances the capabilities of miter saw to make precise cuts safer, faster and easier.

A table saw includes a working surface and a rail system. The rail system includes stationary rails mounted along the working surface, and extension rails. The rails each include matching guide surfaces extending along the longitudinal axis and configured to support and guide a rip fence. The rails have a common connection interface that in each case includes a connecting end and a supporting end, such that the extension rails are mountable with the stationary rails. When mounted, the guide surfaces of the extension rails extend the guide surfaces of the stationary rails. The connecting end in the common connection interface includes a connection mechanism configured to urge the connecting end together with the supporting end to form an internal connection, and to align the guide surfaces of the connected rails to as to be co-planar with each other.
