Abstract
A depth of cut lock mechanism for a plunge-type router having a drive motor enclosed within a motor housing. The motor housing is attached to a base plate by a pair of spatially separated guides. Each guide has a guide sleeve attached to the motor housing and a guide tube attached to the base plate and slidably received in the guide sleeve. The lock mechanism has a lock disc rotatable between a lock position and a release position. A torsional spring resiliently biases the disc toward the lock position and a manually activated release lever displaces the lock disc toward the unlocked position. A brass plug is axially displaced by the rotation of the lock disc to frictionally lock the guide sleeve and guide tube to each other. A ratchet mechanism is provided to adjust the torque applied to the lock disc by the torsional spring and a release lever lock mechanism is provided to lock the release lever and lock disc in a release position.
