Griot's Garage G15/G21 Long-Throw Orbital Polisher *Ground-Up Redesign*

Currently have a G9 and was looking to get a G15. The issues with the G9 and a 5 inch backing plate is that with todays newer cars the G9 stalls a lot. So my question is,
Does the G15 with 5 inch backing plat stall on curves.

G15 will stall more than G9. The longer the stroke of the polisher, the easier it is to stall. Granted some overcome that with extra power but the G9 is plenty strong.

Improve your technique or buy a Flex for forced rotation, nothing stops that.

This may sound counter-intuitive, but try switching to thicker pads or 6.5” pads. I’ve found my G9 actually turns them better on intricate surfaces with less stalling than the 5.5” BOSS pads.

After using my G15 a couple times, I can't imagine how hard I'd have to bear down to stall it out. The motor is pretty stout and drives the backing plate and pads pretty hard. I works hard enough on it's own I've not encountered a situation where I've had to put enough pressure on it to come even close.

Right, but try lifting it and putting the pad at an angle, it will stall easily. That’s why I said if he was having issues it’s likely due to technique. If you keep the pad flat and put normal amount of downforce the machine will keep pad rotation almost all the time. It would have to be a very curvy panel to give you trouble.

This exactly my experience with the G9, Bruno.

My first use with mine, I tried to "finesse" or "dance" it on some curved panels. Stall City. Then, I tried attacking it straight on with just a bit less pressure, and it just kept on churning.

So you haven't had your G15 stall?
 
Thanks for the info. To the folks that gave a G9 and G15, are they much different as far as power/ correcting between the two?
If you have both would you reconsider adding the G15 again or stepping up to a Rupes or Flex.
 
I got the G15 and I can't make this machine stall, it slows down but man I am very happy I got the G15.

Paul - yes, could be as you described with the lower prices on TV's.

All - My question really wasn't aimed at the notion of product quality, although some replies seem to have assumed that. More specifically, I have made a personal decision I will no longer purchase anything made in China where other options exist. No one has to agree with me, and no one has to do as "I do".

It is my belief that we can/should make things here in America (including the downstream supply chain) and employ our own people; especially when the company is American-owned. Again no one has to agree; I speak for myself. Change takes time, and starts with one person and one action.

P.S. I am also in the pro audio industry and the sentiment there is even stronger. Pro audio engineers have put manufacturers on-notice, sending a loud and clear message to manufacturers. It is being referred to as the "Quit China" movement.

Be well,
ScottH

Original boss machiene came out thr Maxshine factory one of the two major ones( other being AutoAnsi? AnsiAuto?)
No idea where they come from now.
My current 25mm longthrow and my in route 3in forced are made in China.. no big deal to me when quality is there..

Feynlabs new longthrow is suppose to he made in USA(looks china to me) but been tempted to trying that one out other than that, makita PO5000C for me(USA)

Id buy Rupes, but i think their mark III are power quality than their old mark II and legacy/ES machines

But I'm sure the no rotation thing may of just been a new release woe and fixed.
