A quick release attachment for a power buffer having a rotatable spindle includes a buffing pad assembly and a quick release connector adapted to join the buffing pad assembly to the spindle. The buffing pad assembly includes a mounting plate and a buffing pad affixed to either side of the mounting plate. The mounting plate and the buffing pads each have respective aligned central apertures. The mounting plate aperture further comprises a circular ring disposed therein and has a pin extending diametrically across the aperture. The pin comprises a magnetically attractive material. The quick release connector has a main body adapted to fixedly engage the spindle. The connector further has a head end extending from the main body and having a circular cross-section sized to engage the circular ring. The head end further has a slot sized to engage the pin. The slot further comprises a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions. The main body further comprises a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot. The buffing pad is selectively affixed to the quick release connector by manipulating the head end into the aperture and moving the pin through the slot until reaching the proximal portion, whereupon the pin is retained by the magnetic attraction of the permanent magnet.

What is claimed is: 1. A buffing system, comprising: a power buffer having a rotatable spindle; a buffing pad assembly having a mounting plate and at least one buffing pad affixed to a side of the mounting plate, the mounting plate having a central aperture, a circular ring disposed within said central aperture and a pin extending diametrically at least partially across the aperture, the pin comprising a magnetically attractive material; and a connector, which is separate and distinct from the buffing pad assembly, having a main body adapted to fixedly engage the spindle, the connector further having a head end extending from the main body and having a circular cross-section sized to engage the circular ring, the head end further having a slot sized to engage the pin, the slot further comprising a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions, the main body further comprising a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot; wherein, the buffing pad assembly, including the mounting plate and the at least one buffing pad, is selectively affixed to the connector by manipulating the head end into the aperture and moving the pin through the slot until reaching the proximal portion, whereupon the pin is retained by the magnetic attraction of the permanent magnet. 2. The buffing system of claim 1, wherein the transition portion of the slot further comprises an arcuate opening on opposite sides of the head end providing transition path for the pin as it traverses the distal and proximal portions of the slot. 3. The buffing system of claim 1, wherein the mounting plate comprises plastic formed via an injection molding technique and the circular ring is embedded within the plastic of the mounting plate. 4. The buffing system of claim 1, wherein the buffing pad assembly further comprises a dual-sided buffing pad assembly with a first buffing pad affixed to a first side of the mounting plate and a second buffing pad affixed to a second side of the mounting plate. 5. The buffing system of claim 1, wherein the proximal portion of the slot is offset from the distal portion of the slot by approximately 90°. 6. The buffing system of claim 1, wherein the at least one buffing pad further comprises a wool material. 7. The buffing system of claim 1, wherein the at least one buffing pad further comprises a foam material. 8. The buffing system of claim 1, wherein the pin is comprised of steel. 9. The buffing system of claim 1, wherein the spindle further comprises a threaded end, and the connector main body has a corresponding threaded interior surface adapted to threadingly engage the spindle threaded end. 10. The buffing system of claim 1, wherein the connector main body further comprises opposed surface regions oriented for engagement by a tightening tool. 11. The buffing system of claim 1, wherein the ring further comprises a circular non-threaded opening. 12. The buffing system of claim 1, wherein the connector main body is comprised entirely of parts that do not move relative to one another. 13. The buffing system of claim 1, wherein the transition portion of the slot provides a direction path for removal of the pin from the slot that is opposite to a direction of rotation of the spindle during operation of the buffing system, thereby precluding inadvertent removal of the buffing pad assembly from the connector during operation of the buffing system. 14. The buffing system of claim 1, wherein the head end of the connector further comprises an outer sleeve. 15. The buffing system of claim 1, wherein the ring further comprises a key centrally disposed in the ring and that includes the pin. 16. An attachment system for a power buffer, comprising: a buffing pad assembly having a mounting plate and at least one buffing pad affixed to a side of the mounting plate, the mounting plate having a central aperture, a circular ring disposed within said central aperture and a pin extending diametrically at least partially across the aperture, the pin comprising a magnetically attractive material; and a connector, which is separate and distinct from the buffing pad assembly, having a main body adapted to fixedly engage a spindle of the power buffer, the connector further having a head end extending from the main body and having a circular cross-section sized to engage the circular ring, the head end further having a slot sized to engage the pin, the slot further comprising a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions, the main body further comprising a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot; wherein, the buffing pad assembly, including the mounting plate and the at least one buffing pad, is selectively affixed to the connector by manipulating the head end into the aperture and moving the pin through the slot until reaching the proximal portion, whereupon the pin is retained by the magnetic attraction of the permanent magnet. 17. The attachment system of claim 16, wherein the transition portion of the slot further comprises an arcuate opening on opposite sides of the head end providing transition path for the pin as it traverses the distal and proximal portions of the slot. 18. The attachment system of claim 16, wherein the mounting plate comprises plastic and the circular ring is embedded within the plastic of the mounting plate. 19. The attachment system of claim 16, wherein the buffing pad assembly further comprises a dual-sided buffing pad assembly with a first buffing pad affixed to a first side of the mounting plate and a second buffing pad affixed to a second side of the mounting plate. 20. The attachment system of claim 16, wherein the proximal portion of the slot is offset from the distal portion of the slot by approximately 90°. 21. The attachment system of claim 16, wherein the at least one buffing pad further comprises a wool material. 22. The attachment system of claim 16, wherein the at least one buffing pad further comprises a foam material. 23. The attachment system of claim 16, wherein the pin is comprised of steel. 24. The attachment system of claim 16, wherein the connector main body has an interior surface adapted to threadingly engage the spindle of the power buffer. 25. The attachment system of claim 16, wherein the ring further comprises a circular non-threaded opening. 26. The attachment system of claim 16, wherein the connector main body further comprises opposed surface regions oriented for engagement by a tightening tool. 27. The attachment system of claim 16, wherein the connector main body is comprised entirely of parts that do not move relative to one another. 28. The attachment system of claim 16, wherein the transition portion of the slot provides a direction path for removal of the pin from the slot that is opposite to a direction of rotation of the spindle during operation of the power buffer, thereby precluding inadvertent removal of the buffing pad assembly from the connector during operation of the power buffer. 29.
