Abstract
A holding fixture for drilling pocket joints with a stepped drill bit. The fixture includes an L-shaped body member having a guide leg that carries an angularly disposed drill guide channel and a clamp leg that supports a clamping mechanism for securing a wooden workpiece flush against the planar surface of the guide leg. The drill guide channel has an upper stop flange and a lower end that terminates flush with the planar surface of the guide leg at a point spaced above the junction of the guide leg and the clamp leg. The stepped drill bit is secured in the chuck of a portable drill and an adjustable stop collar is positioned on the bit. The stop collar engages the stop flange so that the end of the bit is prevented from contacting the surface of the clamp leg. The wooden workpiece is secured flush to the planar surface of the guide leg by the clamp and the pocket and pilot hole are drilled.
