Attachments for a power source such as a rotary drill. Such attachments can be fixedly secured to the power source. Turning power on to the source drives a shaft which drives a gear mechanism which drives a utility woodworking head such as a circular saw or power sander. The power source may be turned on indirectly by a false trigger mechanism slidably attached to a housing so enclosing the drive shaft and assisting to support the apparatus.

An attachment for a rotary power source which has an integral on/off control, said attachment comprising: a gear mechanism; a utility head for performing precision woodworking tasks, said head coupled to and driven to rotate by said gear mechanism; a rotatable shaft attachable to said power source, said shaft rotating to drive said gear mechanism when said power source is on; a housing enclosing at least said shaft, said housing including means for supporting said attachment and including an outer surface adapted to be grasped by an user; and a false trigger mechanism for controlling an operation of said power source, said false trigger mechanism being slidably mounted on said housing and having means for contacting said integral on/off control of said rotary power source to control said power source so as to allow said user to easily control on and off operation of said attachment while grasping said outer surface of said housing, said false trigger mechanism being located closer to said utility head than to said power source, said false trigger mechanism including a false trigger, a trigger extension extending toward said power source, said extension being fixedly connected with said false trigger, and a trigger push for physically contacting said integral on/off switch of said power source, said trigger push fixedly connected to said trigger extension so that when said false trigger slides, said trigger push slides accordingly.
