A spindle flute jig for woodworking is disclosed. The flute jig is freestanding and independent of woodworking lathes. The flute jig comprises a base, a carriage, an upper frame positioned substantially parallel to the base, a drive end, a pivot end, an adjustable plunge router stop, a fixed plunge router stop, a tool storage section, and a marking block.

A barrel cam device includes a barrel cam, an output table that includes a plurality of cam followers that engage with the barrel cam, and that rotates by rotation of the barrel cam, and a clamp device that clamps the output table when the output table is stopping.

A truss assembly table and methods of operating a truss assembly table, wherein the truss assembly table includes one or more of truss ejection assemblies, truss end stop assemblies, and a control system and gantry with a sensor assembly.

A machining stop preferably includes a retention member, a base post, an adjustable stop retainer and a tool stop. The retention member preferably includes a stationary retention portion and an adjustable retention portion. An end of the stationary base member is engaged with an end of the adjustable base member. The base post is attached to the stationary retention portion. The adjustable stop retainer includes a post bore and a tool stop notch. The post bore is sized to slidably receive an outer perimeter of the base post. The tool stop notch is sized to receive the tool stop. A height fastener is threaded through a wall of the adjustable stop retainer. A tool stop fastener is threaded through a wall of the adjustable stop retainer. A plate machining stop preferably includes a plate retention member, the base post, the adjustable stop retainer and the tool stop.

A clamping arrangement has a clamping device is fastened fastenable on a clamping base, and a clamping element able to be tightened thereon. The clamping device has a clamping module with clamping members that can be fixed by a fixing element on the clamping base, wherein the fixing element is configured such that the clamping module is fixed in the X-Y plane in a floating manner. The clamping module is displaceable in the fixed state of the fixing element with respect to the fixing element in the X-Y plane, but is non-displaceable in the Z-direction. The fixing element is provided with Z-support surfaces for the clamping element. The clamping arrangement is particularly suitable for a large clamping system, so that thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with repeatable accuracy, without the clamping system being over-constrained geometrically/mechanically in the X-Y plane.

This disclosure describes systems, methods, and devices for accurately locating the center mark for a center punch on a metal strut, which is commonly used to support cable trays and pipes in various industries. The device solves the problem of inaccurate center marking by using a center punch and a punch alignment guide. The guide sets the punch in a precise position, and by placing the device on the strut and pressing a button, a small indentation is made on the metal to mark the center point accurately. This ensures that drilling or cutting tools do not slip or wander and that holes or cuts are placed accurately.
