Griots g9 broken?

[JustEd]

I was a little apprehensive to order a G9 since some Youtubers were experiencing some problems with it but for Black Friday I ordered it from Autogeek, it arrived really fast and I was itching to use it but because I had an accident nearly 3 months ago the body shop recommended that I wait at least 90 days to let the paint cure. Last Saturday I set on polishing the car. When I ordered the G9 neither Griot's Garage nor Autogeek had the 5 " backing plate in stock so I used my old MaxShine one, it did work but stalled quite a lot even on the flat panels. I'll be heading to So. Florida this weekend so I'll stop by Autogeek to buy the recommended backing plate. It should work fine after this.

Get a G6 put it on speed 6 on a flat panel and you won't be able to stall it using a lot of pressure. Get the same pad combo and do it on a curve and it will stall easily. Same applies to any free spinning DA including the G9. It depends one how sharp the curves are and how much pressure is being applied.

Makes logical sense there. Same applies to the Porter Cable DA, Duetto, etc., any 'free wheeler". Reckon if one never wants to deal with possible stall with a DA, then a Flex 3401 or Rupes Mille is the ticket.

I’ll weigh in in this again. My original G9 failed and was replaced. Haven’t used it as of yet but I have my fingers crossed. When I used the first one, I was kinda of impressed with the lack of stalling. This was with the 6” plate and 6.5” boss pads. While waiting for the replacement, I bought the G15. Using the 5.5” boss pads it stalled more frequently than the G9. Also have a maxshine M21 pro with a 6” plate it stalls slightly less than the G15 with Boss pads.
Recently purchased the G8. For those of you following the G8 thread, you will see it needs to go back. Speed fluctuates wildly regardless of which cord I use. I own 92) 10’ and a 25’ cord. I replaced the brushes which were worn uneven. This didn’t make a noticeable difference. I ran it unloaded for about 10 minutes and used it today. No changes.
2 common denominators here. First is all free wheeling DA’s I’ve used stall to some degree. Either a little technique change, pad change or matching the pad size to the panel will get you through. Secondly, I believe Griots unveiled both the G8and the G9 starting they had a new partner. It seems they might need to have a sit down before their reputation takes too big a hit

Like with any new product, it will have some bugs that need to be worked out. This is why I won't buy a first new model car.

Big time.

I was at another dealer on Tuesday. (Ford/Lincoln. We are only Ford).

He told me that the new Aviator's (built on the new 2020 Explorer platform) are FULL of problems/recalls.

And these are around 75-80k. Not 150 bucks.

With more than 38 years in the industry now, my experience is that first-year new models are among the highest in build quality but experience more problems with purchased parts because suppliers are not in tune. At the assembly level, an almost-OCD level of attention is paid to new models, not to mention all the body-in-white, pre-pilot, pilot, pre-production, and other trials that are done prior to commencing full production. In the end, it's still pretty amazing to see 30,000+ parts go from part print to becoming a complete auto. Nothing else so complex is built in such a mass production quantity.

Agreed.

And on a smaller note, I'm sure the G9 is the same. OCD as they may be, there will be some unforeseen bugs.

I actually just ordered a G9 from Autogeek. The product page says ships in 4-6 weeks, and I received an email saying that it is on a “manufacture back order”, yet if you go to griots website, the G9 says “in stock”. If it was on a manufacture backorder, wouldn’t that imply that the manufacture had none in stock? I was curious if there was in fact a revision in the works causing the delay.

It's usually down to some chintzy supplier working out of a one-room shop who doesn't understand geometric tolerancing or "forgot" to read all the specs ... :laughing:

P.S. - There is actually a product approval/certification process for all supplied parts. But you wouldn't believe how often parts get "signed off" by some moron, or worse, by a moron who got his pockets lined. That's why we have a (supposed) ban on engineers and purchasing people receiving gifts from suppliers.

Ever heard of retail and wholesale? The retailer (Griot) may have stock, but the wholesaler side of Griot that supplies AG may be out of stock.

My question is, can you finish multi step using a mille?

I'm certainly no top authority here to toot my horn on some subjects, but, are you asking can one machine such as the Rupes Mille or Flex 3401 do it all?

From heavier cutting with compounds and coarser Pads to finesse finishing and jeweling-etc with milder polishes, glazes, waxes, with ultra soft pads? Or one step products?

The answer is yes. Their only limitations are their larger size.

The same holds true with a Rotary Polisher. And if such can be done with Rotarys, then these two machines can too.

The key is the learning curve, and learning the use of that particular machine.

In reference to an old video by the "Junkman" I once watched, he was explaining the various machines out there, and when he picked up the Flex 3401, he said, "Can this bad boy get you in trouble, and burn your paint"? His answer was yes. Same holds true with the Rotary Polisher to an even higher degree.

Not to mention a Rotary in inexperienced hands can turn a paint finish into a holographic mess.

Such machines like the Flex's and Rupe's direct drive's correction abilities will be factored and adjusted-controlled by the products, the pads chosen, the degree-amount of down pressure upon the pad, arm speed, and number of passes.

Oh, and let's not forget these machines both have speed dials.

Unlike free wheelers, one can then use slightly slower speeds as well, not needing "pedal to the metal" speeds to attain efficient correction due to stall.

Mastering these machine's abilities comes with experience, time, practice, the perfection of the hand, the eye, and the wise choice and selection of products-pads used.

Hope this helps.

 

[MarkD51]

I'll make another intelligent claim, that professionals likely turn to these machines such as the Mille, and 3401 as their real bread and butter money makers because of their consistency of correction abilities.

That many don't wish to struggle and fight with the inherit variability of pad rotation that can produce inconsistent end results.

A pro wants to know they're getting the exact same working results from the machine, once they're dialed in, that's it, one less problem and worry to fight, that constant "eyeballing" of a Plate's rotation due to body curves, variation of down pressure, and other factors.

I'm sure many still keep machines like the PC7424XP, GG6, etc., in their arsenals and that they have uses for them, but overall, I would think once they graduate to the Flex or others like the Rupes Mille, the lesser machines are actually a PITA for them to use. One important factor to a professional, is "time is money".

Griot’s keeps products in high demand for their own stock first before supplying resellers. The G8 has only been shipping from Griot’s directly, resellers won’t get any until mid to late January.

Ken,

Thank you for the email! I contacted Griot's and they said, "There is no “2nd” gen G9 being planned or in production. There isn’t any flaw with the G9 itself that would necessitate it. Some misinformation was accidentally given, but overall there aren’t any changes needed at the moment.". If you have any other questions please let me know. Take care!

From Griots
Hello Ken,

Thank you for taking the time to email us here at Griot's Garage. We are shipping the G9 and G8. If there are any issue with any of our items – just give us a call and we will try to troubleshoot over the phone. As always we have 180 day money back guarantee and life time warranty against manufacture defect.

 

[Mike@ShineStruck]

I did not know that, but I wouldn't say Adam's copied the design. The G9 was announced just what, a few months ago right? Both probably had a similar idea for the cord, I can't see Griot's announcing this in September and Adam's having a copy cat out this quick. I would imagine R&D takes a ton of time. Not to mention Adam's probably had at least a 500-1000 made for the 1st run which would take a good while.

I deal with over seas Polisher manufactuers... If you dig around.. Or talk to a couple guys youll undersand more how it works
