Griots 6" DA. Generation 1 -vs- Generation 2

[Flash Gordon]

The first model didn't work, at least it wouldn't maintain pad rotation under pressure.

There are a lot of oribtal wood sandiners on the market and for the most part only the Porter Cable and the tools modeled after the PC will actually rotate and occillate foam pads under pressure.

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.

Now thats very intresting

Leave it to Master P to reach for the roots of the matter :righton:

My old style PC7424 came with that dust evac system. I have never used it for sanding, so, never used the evac.

I bet they did power them down a little. Mine will eat pads at speed 6. It is a monster. I bet they got tired of replacing pads.

Flash, you must not be getting the right tech people. I used to ask for Dustin. Not sure he is still there. I have not had a tech problem in a long time (once I turned my speed down to 5 and quit smoking pads.)

sometimes batches (in this case motor) will vary and may not be consistent with previous (kinda like microfiber towels) perhaps. it would be nice to get the same exact product (like in anything) everytime, but when they produce thousands it's sometimes not very likely. it's hard to get the same exact thing each and every time...

I understand that and that may very well be the case. The reason I think they may have changed it is because when I bought mine I called about it damaging pads.

I asked them about the problem. They were telling me no pressure, let the machine do the work, only speeds 4 to 5, etc. When I first got started (I started with Griots 10 or 12 years ago when they sold the PC7424 with their sticker on it), they were telling me the opposite. Even when I looked at this generation GG6, it was speed 6, moderate pressure, etc.

I got the impression they were having problems with them eating Griots own pads. One of the techs said something to me about delaminating pads.

I think there might be a difference in the newer generation of GG 6" polishers. I have seen one with the rotary switch in the back with white numbers and another with black numbers. Both seem to work well and I havent been able to compare them at speed 6 because I have never found a need to go that high.

My Griots, which I bought this May, ate a Griots polishing pad. I called them and they sent me a free pad. It ate two LC orange flat pads on a soft Toyota hood two weeks ago. I can't stop it from rotating on speed 6 nor 5. It is a beast and I need pads that can go the distance.

I forgot how heavy the GG machine is .

Update:

After polishing 4 cars with the new machine, I've come to the conclusion that the new generation is better then ever. Less vibration and still as powerful as before

I recommend that everyone should have one of these in their arsenal :buffing:

Was it ever determined whether Mark's GG's were defective or were they the newer less powerful new version? I bought my GG this past May and it is very powerful---I can't stop it on speed 6 nor 5. I don't intend to get a new one anytime soon, especially since it has life-time warranty. I was under the impression that the newer ones had less vibration but less power.

I don't think Mark has been back to visit this thread, so who knows

IDK what they did, but the machine is much smoother to run on 6. That or I had a defected unit to begin with

Nonetheless, I was able to remove some very nasty defects on 4 different make/models. The testing will continue :buffing:

Now that we're speaking on speeds over GG ROP....
Do you guys think it would be possible to make corrections with it on speed 4 or 4.5 as speeds like 5 or 6 are generally recommended to PC and meg's v2 which are both less powerful than GG Rop ?

I mean... I think we all agree that on a flat panel it's really hard to stop a 5.5" pad on the GG ROP from speed 5 and above...

For me, to get the pad to rotate from 1-2 rotations per second (in order to make a smooth orbital motion), I need to put a good amount of pressure at speed 5. On 6 it's almost impossible to spin down the pad that much.... I usually go to 6 only when doing curved panels that tends to stop the pad.... which I really don't know if it's the right approach....
