Abstract

A jig for finishing a workpiece with a handheld router or other handheld motor-driven rotational tool assembly is provided. The jig includes a baseplate that is precisely aligned and attached to a router. Guides, including a main guide and a support guide, are provided. The main guide is configured to precisely align with and fasten to the base plate in several different jig configurations. Right-angle adaptors attach to the guides and precisely align with and attach to the guides and the base plate to form several different jig configurations. Side plates secure the workpiece therebetween and provide a surface along which the main guide may slide to facilitate finishing operations on the workpiece.

Abstract

A firearm and a jig for modifying or constructing a firearm with a locking magazine release button is provided. The firearm has a lower receiver including a magazine locking pin aperture disposed in an upper surface thereof where the magazine locking aperture intersects with a magazine release button aperture in a side surface of the lower receiver. The firearm also has an upper receiver attached to the lower receiver via a pivot pin, a magazine attachable to the lower receiver, a magazine locking pin inserted into the magazine locking pin aperture, and a magazine release button comprising a recessed locking catch. The magazine release button releases the magazine when the upper receiver is away from the lower and the pin is not in the magazine locking aperture. The button is inoperable when the upper receiver is next to the lower receiver and the pin engages the locking catch.
