CROSS REFERENCE TO RELATED APPLICATION

This application is a divisional of U.S. patent application Ser. No. 15/877,325 filed Jan. 22, 2018, entitled “Driver Shaft Jig Assemblies, Setup Assemblies, and Cutting Assemblies”, which claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 62/471,814 filed Mar. 15, 2017, entitled “Driver Shaft Jig Assemblies, Setup Assemblies, and Cutting Assemblies”, the entirety of each of which is incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates to driver shaft support assemblies, driver shaft setup assemblies, and driver shaft cutting assemblies. Specific implementations of the present disclosure provide embodiments that can include screwdriver shaft support assemblies, setup, and cutting assemblies as well as an overall assembly that utilizes these three assemblies to prepare a customized driver shaft tip and/or clean up a damaged tip.

BACKGROUND

As craftsmen work with mechanical devices such as those devices which are utilized and/or manipulated in the practice of removing threaded fasteners, various dimensionally correct shaft driver tips are required. Precisely shaped and dimensioned shaft driver tips may have been utilized by the original craftsmen that designed these original mechanical devices, but however are no longer workable and/or are no longer available from commercial providers.

For example, in gunsmithing, it may be necessary to remove a screw in an effort to disassemble the gun for servicing without damaging the screw and to replace the screw without damage when reassembling the gun. It may be that commercially available screwdrivers will not sufficiently remove the screw, as they are shaped improperly or have the improper dimensions to remove the screw without damaging the screw head itself, which may diminish the functionality, originality and/or artistic value.

The present disclosure provides assemblies that can be utilized to prepare and shape custom driver shaft tips that can be utilized to precisely fit screw heads and manipulate those screw heads without damaging the screw head itself.
