Abstract: Guide vane check valve assemblies and poppets for guide vane check valve assemblies are disclosed. A guide vane poppet includes an elongate central core configured to form a fluid seal with a valve body of the check valve assembly. The guide vane poppet additionally includes an elongate outer skirt and at least one guide vane radially extending between the elongate central core and the elongate outer skirt. A check valve assembly includes a valve body with a central cavity, an inlet to the central cavity, an outlet from the central cavity, and a spring seat, and further includes a spring and a poppet. The spring is oriented to press against the poppet and to urge a poppet-side sealing surface of the poppet into sealing engagement with a body-side sealing surface of the valve body.

Abstract: The router table push shoe 10 of the present invention has an upwardly extending handle 11 which is angled slightly towards the operator and away from the router table fence 55. The push shoe of the present invention comes with an adjustable bottom guard 20 removably attached to the base 40, and an adjustable side guard 12 which can be removed and used as a bit height measuring tool. Both the bottom guard 20 and the side guard 12 are adjustable to enable the push shoe 10 to hold thin and narrow stock. The push shoe 10 also comes equipped with a miter bar 30. The horizontally adjustable bottom guard 20 is removably attached to the base 40 via a three wing knob 22. The push shoe also has formed in the front right corner a dovetail gauge 17 for making both male and female joints for sliding dovetail joints.

Abstract: A pair of routers are serially mounted on a pivotable support on a cutting table such that the routers may be adjusted in unison relative to the table. In addition the routers are adjustable relative to each other in a seesaw manner about a central cutting axis so as to maintain the axis. The apparatus and process of the present invention is particularly useful for making the male and female cuts of a dovetail joint in a single operation without requiring any adjustment of the routers relative to each other after the initial positioning. Depending on the cutting tool employed, dovetails, splines, rabbet cuts, mortise and tenon joints and countless other cuts may be made.
