5" or 6" pad on a G8?

[webdweeb]

I recently purchased a G8 for the smaller pad footprint (I also got the 1" and 2" plates and pads), but I am now wondering if this same polisher would work with a larger (5" or 6") backing plate. When I look at the specs of the G8 and G9, the only differences I see are: (1) orbit/throw (8mm for the G8, 9mm for the G9), (2) current draw (6 for the G8, 8.5 for the G9) and the handle style (no drive head grip for the G8 as is on the G9). I already own an old but still functional PC 7336, which I originally purchased as a sander for work on solid surface countertops (it was DuPont's recommended sander/polisher for Corian back in the 90s), but also works well as a general purpose polisher (I've used it on my cars as well as finished furniture with success). Another data point that is relevant: the 7336 current draw is 3.7A, which is about 60% of that of the G8, so the G8 would also give me more power if I needed it vs the PC. Anyway, I thought I would ask the forum members if anyone else has used a larger pad with the G8, and if so, how that worked out. I plan to do a test run with the larger pad to see how it works (on a non-critical surface), and will report back on the results, but any feedback on this option would be most appreciated.

My guess is it will stall flat on it's face...under powered machine....yes I own one

I'd also think that it wouldn't be very balanced. The extra backing plate/pad weight wouldn't be what the G8 counterbalance was designed for.

If it did, it would be truly an all in one polisher.

Nope.

it would put more load on the tool and decrease the effectiveness as well...

Try it. Personally I wouldn't expect much..

Thanks all for the feedback. I spoke with someone at Griot's who confirmed that the counterbalance on the G8 would result in more vibration with a larger pad. The PC has served me well but is showing its age, so I am considering adding a G9 to my tool box - maybe I will add it to my Christmas list!

You will not be disappointed...............

I should have my cordless SPTA 15mm in a few days. I'm expecting it to be a game changer with no cords.

Cordless tools are VERY nice, the ones that i have used at work. Mostly dewalt and millwakee.
