Repositionable abrasive disc mounting assembly and method of using the same

A method for repositioning an abrasive disc within a repositionable abrasive disc mounting assembly, the method comprising:

• mounting the abrasive disc to a repositionable abrasive disc mounting assembly in a first position, wherein the mounting disc assembly comprises:
• the abrasive disc coupled to a back-up pad assembly such that the abrasive disc is in contact with a pressure feature of the back-up pad assembly;
• a drive shaft of a grinding tool;
• and a fastener that maintains the position of the abrasive disc and the back-up pad coupled to the drive shaft;
• conducting an abrasive operation by activating the grinding tool;
• re-positioning the abrasive disc, with respect to the repositionable abrasive disc mounting assembly, in a second position, wherein the first position comprises the abrasive disc in a first position relative to the pressure feature and wherein the second position comprises the abrasive disc in a second position relative to the pressure feature;
• and
• wherein re-positioning comprises an adjustment between the first and second position while the abrasive disc is still positioned on the drive shaft between the fastener and the back-up pad assembly, and wherein a first repositioning comprises a first distance between the first position and the second position, and a second repositioning, between the second position and a third position, comprises a second distance different from the first distance.
