Burrless flexible track drilling system and method having counterweight tool balancing system

A method for ergonomically performing burrless drilling through a pair of adjacently positioned components used to form a body portion of said mobile platform, the method comprising:

• securing at least one track in a vertical orientation on one of said components adjacent an area where a machining operation is to be performed;
• securing a machining subassembly having an electromagnet to said track to permit said machining subassembly to be moved along said track by an individual;
• using a counter weight subsystem to support said machining subassembly to enable said machining subassembly to feel substantially weightless to an individual as the subassembly is moved along said track by an individual with a low degree of physical effort;
• and
• positioning a backing plate for movement adjacent to a surface of one of said components that is facing oppositely to a surface to which said track is secured;
• positioning said machining subassembly to a desired position;
• energizing said electromagnet to cause said backing plate and said electromagnet to clamp said components together;
• and
• using a drill supported by said machining subassembly to drill a burrless hole in said components.

• at least one track arranged in a vertical orientation on one of said components adjacent an area where a machining operation is to be performed;
• a machining subassembly having an electromagnet supported on said track to permit said machining subassembly to be moved along said track by an individual;
• a counter weight tool balancing subsystem to support and enable said machining subassembly to feel substantially weightless to an individual as the subassembly is moved along said track by an individual with a low degree of physical effort;
• a backing plate disposed adjacent to a surface of one of said components that is facing oppositely to a surface to which said track is secured;
• the electromagnet being operable to use said backing plate to magnetically clamp said components together prior to beginning a drilling operation;
• and
• a drill disposed on said machining subassembly for performing a drilling operation on said components.
