Just tried out Excel Detail's 3" backing plate with the 4" pads and at speed 6 the vibrations seem twice as much as the 6.5" pads with a 5" backing plate.
Is this how it's supposed to feel?

I can't wait until I can go to the larger pads for some smooth running. | |

From what I've read I thought they don't make a difference, but that is with a 5" BP and 6.5" pads.
It feels so much better with the bigger pads and BP's on the PC, kind of frustrating.
The vibrations are liveable at speed 5, but once I crank it to 6 it feels like it's going crazy!

Consider vibration-absorbing gloves
Make sure your pad is centered on the backing plate.
If all else fails buy a Cyclo  I mean seriously, I wouldn't use a machine that actually *hurts* me to polish a car or to do anything else that's not of life-and-death importance. If there's any way you can swing the cost of a Cyclo (maybe buy a used one off the big auction site) it'll last forever. | |
