Give it a try on a test panel...use a 4" pad and a 6.5" pad, hold it in one spot for a certain amount of time and see how hot each one gets. The 4" will probably burn thru and be VERY hot. |
sorry ...but your wrong
on a rotary 1000 RPM = 1000 RPM the force does not change the # of rotations
also the outer edge will spin about 1/2 as fast @ any given RPM then a 8" pad
less speed = less heat
