ABSTRACT:
A device for full depth hand routing characterized by a two piece base including a foot block and an attachment block, the attachment block being held to the foot block by a connector bolt and two adjusting screws to enable attaining parallel planes for a tool in the base of the block; a cantilevered holder extending from the attachment block; a tool on a shaft that is powered by a motor within a housing that has a substantially cylindrical barrel and a protruding threaded male part threaded engaging a threaded aperture on the cantilevered holder; an indicator scale around the base of the barrel and above the threads; and indicator carried by the attachment block and extending upwardly adjacent the depth scale such that accurate depth positions can be attained for routing to a desired depth. In a preferred embodiment, the cantilevered holder comprises a ring that allows 270.degree. visibility about the routing tool. Also in the preferred embodiment, the foot block has an upstanding flange at 90.degree. and the attachment block is held cantilevered from the upstanding flange by the connector bolt in a slot. The base block has rounded sides for traversing an irregularly shaped object such as an aircraft wing for attaining full depth routing.
