6" Counterweight 4 the PC - Not required??

In supporting my canadian group buy, several of us are picking up a W64DA - the velcro backing plate by Meguiars. Here's where things get a bit interesting.



The G100 (Porter Cable relabeled for Meguiars) comes with a 5" counterweight and doesn't require changing! So then I check the size of the backing plate and it slightly under 5". Granted the pads are 6" but the velcro on the back of the pads is 5".



I then called Meguiar's and they also feel that changing the counterweight to a 6" on a Porter Cable 7424 isn't required.



I'll call Porter Cable on Monday (customer service is closed on the weekends) and see how they think about it.



I haven't had a chance to look at the size of the Porter Cable hock and loop version or the 3M one but I seem to recall they were 6". If that's case, then it would be understandable why you need to change the couterweight as most of the weight is associated with the backing plate and not the few ounces that a pad weigh. Anyone out there with the 3M or PC plates, any insight?



Something to consider if you're using a Meguiars hock and loop plate.

With the PC, I read that when you use the 54745 6" Foam Polishing Pad. Due to its light weight and the small-diameter backing pad used (included with pad), it can be used with either the 5" pad or 6" pad counterweight.



Or just buy the 6" counterwieght for the $1.95 plus shipping that www.coastaltool.com has them for.
 
But I do have a source locally and will be picking them up on Tuesday anyway.



Good know that you can use though without it :up

I've run my PC with rubber contour pad (with heat holes :rolleyes: ) with both the 5" and 6" counterweights and I can't feel a difference in vibration.



How smooth is my PC supposed to run? Mine is rather un-smooth.
 
If you have the 5 inch backing plate, then the 5 inch counter weight is fine.



I use the PC 7424 with the 5 inch counter weight with CMA's 5 inch backing plate and 6 inch CMA pads (5 inch lambswool and terry though, darn those terry things are rough, use them to cleaner/wax beaters.)



Vibration, sure there are some, but I can't compare it to anything. I do have pretty well worked arms after using it for a day, most people thing that my forearms are so hard because I master...well I'm not getting into that lol :)



Expect some vibration, should be like hmmm, holding a plam sander X2.
