Abstract
A pin router arm for attachment to a router table, and a mechanism that attaches to a plunge router to conveniently and accurately move the router body relative to the router base in order to adjust the position of a router bit in the router relative to the router table. Substantial excursions in router bit position are made by moving a handle up or down using a handle or a foot pedal, and small excursions are made using a micro-adjust mechanism that has a detent set screw and cooperating structure to facilitate adjustment of the micro-adjust mechanism by very small predetermined increments. The pin router arm can hold interchangeable sizes of guide pins and is easily and quickly mounted on and removable from the router table.

Apparatus for use with a router, a router bit and a router table to provide pin router capabilities, the apparatus comprising:
- (a) a guide pin mechanism for holding a guide pin in either a raised or lowered position,
- (b) an arm for attachment to the router table and for holding the guide pin mechanism above the router table in multiple positions along an axis normal to the router table top, wherein the arm holds the guide pin mechanism in a collar closable about the guide pin mechanism with a locking knob attached to a threaded shaft.
Apparatus for use with a router, a router bit and a router table to provide pin router capabilities, the apparatus comprising:
- (a) a guide pin mechanism for holding a guide pin in either a raised or lowered position, wherein the guide pin mechanism comprises:
- (i) a shaft having top and bottom ends and a bore in the bottom end within which a portion of the guide pin is received, and
- (ii) a tubular housing having a longitudinal bore within which the shaft is secured to move between the raised and lowered positions,
- (b) an aim for attachment to the router table and for holding the guide pin mechanism above the router table in multiple positions along an axis normal to the router table top.
Apparatus for use with a router, a router bit and a router table to provide pin router capabilities, the apparatus comprising:
- (a) an arm for attachment to the router table,
- (b) at least one clamp for securing the arm to the router table, and
- (c) at least one adjustable stop for repeatably positioning the arm on the router table in a desired location.
