Question on Counter Weight
Hi, does anyone know is the counter weight for the PC7424 and griot garage DA (das pro) interchangeable? One of my friend manage to break the counter weight on his das pro and is currently looking for replacement.

Re: Question on Counter Weight
Not kidding here.....have you tried Super Glue yet?
Does the DAS have two screws that hold the counter weight to the polisher?
Post some pictures, please

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.
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.

Re: Question on Counter Weight
Just checked for you. They're very similar and do inter change but are not exactly the same. The stock weight on the GG is 61 grams. The 6 inch weight for the PC 59 grams. The 5 inch weight for the PC is 49 grams

Re: Question on Counter Weight
The discussion makes me wonder if i should modify the counterweight in my PC to reduce its weight since it is dedicated to 3-4" pads and Cyclo brushes

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:

To me, in order to have a smoother operating PC7424, it would make more sense to leave the standard 5" counterweight for the smaller-sized foam pads/backing plates...and go to a more heavier (~75-80 grams) counterweight for larger-sized foam pads/backing plates.

Re: Question on Counter Weight
Wait, what? I've only ever used 5" BPs and pads on my PC. Am I to understand there are different counterweights available? How would I know which one I got?
