Claim:
A screw removal tool for removing a screw from a missile, comprising: a c-shaped frame having a lower extension and an upper extension, said c-shaped frame configured and dimensioned to receive a missile having a screw removably embedded therein; an adjustable contact plate on an inner surface of said lower extension of said c-shaped frame; a lower drive screw that passes through an aperture in said lower extension of said c-shaped frame, said lower drive screw being associated with said adjustable contact plate such that rotating said lower drive screw causes said adjustable contact plate to move radially with respect to said lower extension and contact said object when said screw removal tool is mounted on said missile; a seat guide to contact an outer surface of said missile about 90 degrees from center of said missile from where said adjustable contact plate contacts said missile and from the location of said at least one screw removably embedded in said missile when said screw removal tool is mounted on said missile, said seat guide sitting on the inner surface of said c-shaped frame between said lower extension and said upper extension; a bit having at least one hatch matable with at least one recess on a head of said at least one screw removably embedded in said missile; a socket removably mated with said bit; a sleeve that passes through an upper extension aperture in said upper extension, said sleeve having a threaded inner recess, said sleeve having a groove, said sleeve passing through said aperture in said upper extension at a location directly opposite said adjustable contact plate; an upper drive screw passing through said sleeve; said upper drive screw having a connector portion and a threaded portion, wherein said connector portion is adapted to mate with said socket and said threaded portion is configured to threadingly associate with said threaded inner recess of said sleeve, said threaded portion having a thread pitch that matches the thread pitch of said screw removably embedded in said missile; said upper drive screw having a head that includes a square shaped groove to receive a socket fitting; a set screw; and a knob having an knob aperture and positioned to sit on an outer surface of said c-frame such that said knob aperture vertically lines up with said sleeve aperture; said sleeve passing through said knob aperture; said knob having at least one setscrew aperture through which said setscrew passes and associates with said groove such that rotating said knob causes said sleeve to rotate; said knob adapted to adjust radial orientation of said bit without rotating said upper drive screw by rotating said sleeve; said upper drive screw, said sleeve, and said knob cooperating to simultaneously move said upper drive screw radially with respect to said upper extension and rotate said bit co-axially when said upper drive screw is co-axially rotated and said knob is not rotated.
