Concrete slab rebar hole doweling cart
A rebar hole doweling cart to construct or repair sidewalks, driveways, roadways, curbs, floors and the like. The cart has a frame with wheels, an elongated upwardly extending riser with a handle, and a nose plate that pivotally supports a drill mounting assembly near the ground. The mounting assembly holds an electric hammer drill and its bit in an aimed direction. The cart is rolled forward to tap a hole in a concrete slab and place the bit in a set aimed direction. The cart handle is then pushed forward to rotate the nose plate down into gripping engagement with the ground to advance the drill bit forward to form the rebar hole in the slab. During this forward handle rotation, the drill mounting assembly simultaneously counter-rotates (pitch pivotal movement) relative to the nose plate to maintain the drill bit in its set aimed direction.
