In my article here,
The Free Floating Spindle Bearing Assembly - The Story Behind The Story...
Where I explain what the drive mechanism is called, (specifically), and also share how the DA Polisher that we all know and love today started out as a Wood Sander.
In this article I have pictures of the spindles and counterweights for PC, Griot's and Meguiar's.
Here you go...
It looks quite possible that the bolt spread pattern for the Griot's and the PC are the same. That doesn't mean the counterweights will fit as there could be design differences in the fitment and shape.
:dunno:
And here's just a portion of the above article....
Frustration with clearcoat paints
Now let me tie this back to why machine polishing has become so much more popular since clear coat paints were introduced.
As more and more cars being manufactured made their way into the market, as car owners, or in other words, do-it-yourselfers, would try the traditional methods of removing defects out of the paint, that is with traditional rubbing and polishing compounds, they would find that most of these products may remove defects but leave their own defects in the paint at the same time.
Not only that, but because generally speaking, modern clear coats are harder than single stage paints, the energy, time and skill required to actually remove defects out of clear coat paints increased dramatically, and in fact increased to the point that many people attempting to remove defects and restore a shine like their car had when they bought it brand new, left most people feeling frustrated and their cars no better off than when they started and often times worse.
Enter the Porter Cable DA Sander
That's right, I said sander! The Porter Cable Dual Action Sander is the tool that became the Tipping Point that was the driving force behind the average person switching from working by hand to working by machine.

Hmm.. I can suggest that to my friend but honestly it just seems so unsafe doing so. Imagine all the heat generated from a DA; the motion; a piece of metal potential flying out anywhere.
Thanks Mike for the pic. The DAS is similar to the griot. On a side note, just want to say that buffing without a counter weight regardless on a 5 or 6 inch pad is awfully unbearable.

Thanks for the link Mike. I saw that thread before. In fact I ask because I saw from that thread that the counter weight on both PC and griot looks so similar. I just dont have both machine on hand to test.
Any kind soul who has both machine and willing to help.:help:

6" to 5" on the PC is a 20% reduction in the weight of the counter weight
I wonder if it would be a good idea to reduce the counter weight another 20% to 39 grams if you are using 4" pads?

In my opinion: No.
And from another thread wherein counterweights were discussed:

They usually come equipped with a counterweight that's stamped as follows:
Your PC may be an anomoly, though, and came equipped with this counterweight:
