Metal-polishing technique

A metal-polishing apparatus comprising:

• a) an arm assembly comprising:
• i) a first rod having a top end and a bottom end;
• ii) a second rod having first and second ends, said top end of said first rod being transversely connected proximate to said first end of said second rod, said second rod rotatable in relation to said first rod;
• iii) a third rod having a top end and a bottom end, said second end of said second rod being transversely connected proximate to said top end of said third rod, said third rod rotatable in relation to said second rod;
• iv) a first actuating device coupled to said top end of said third rod;
• v) a passage coupled to said first rod and said first actuating device;
• vi) a handle coupled to said third rod;
• vii) a brush assembly transversely connected to said bottom end of said third rod, said brush assembly operatively coupled to said first actuating device;
• b) a table assembly, said table assembly comprising:
• i) a frame assembly coupled to a second end of said first rod, said frame assembly including a second actuating device coupled to said frame assembly;
• ii) a table-top assembly having a lower surface rotatably coupled to said frame assembly and operatively coupled to said second actuating device so that operation of the second actuating device causes the rotation of said table top assembly, said table-top assembly comprising:
• a) a circular plate having at least three orifices wherein one slider is coupled to the opening of each orifice;
• b) a pivot cam coupled to a top surface of said table plate, said pivot cam having at least three ends;
• c) at least three connecting arms coupled to said ends of said pivot cam and said slides, said connecting arms being in contact with said orifices when said pivoting device is in a first position;
• and
• d) an engaging mechanism for engaging a rod coupled to said pivot cam wherein engaging of said rod causes said pivot cam to be in said first position.
