Backing plate failed

It's nice that Mike P is also going above and beyond to help you personally. I suspect a favorable outcome for you.


I sent the link for this thread to Rod Kraft, he was my special guest at the last 3-day bootcamp class we had in September. He's a SUPER guy!

He replied back and said,

Hi Mike,

I’m on it!

Thanks for sending this!!



I would guess anything, that is any contact from anyone in this thread with Griot's Garage customer care, they are aware of you and this thread. They offer top notch customer service and I believe you can trust them.

I also mentioned to Rod about Bill's experience with his broken backing plate.

I appreciate that. With the right plate I can use my polisher with confidence. I have a scratch repair job coming up for a friend.
 
I had a similar experience but I think the pad manufacturer failed me.

Note the pad is NOT carried by AG so lesson learned for me. 5.5" pad on 5" backing plate.

Should have known this pad woukd fail when the prior one deformed and I reached for a this new one. As I was getting ready to remove this one and thankfully at the last minute before a disaster.

Just got off the phone with GG, new backing plate is on its way.

Alan, gentlemen I spoke with, told me they use spd 4 for cutting and have never needed spd 6 as it’s overkill. Talked about technique and I mentioned the pads I was using didn’t have the hole, he said the polisher really needs that hole to get rid of the heat. So I’m gonna try and drill a hole I’m a pad and see how it works, probably need to punch it rather than drill....

Either way I’m very happy with the customer service as I knew I would be. Now to slow the machine a bit and see what happens.

Thanks for the update. I kind of figured that running at a lower speed would be the correct way. Similar to the Rupes tools with not needing anything above speed 4. I have not had issues using the meguiar's microfiber pads on the Rupes running at speed 4. Swap them out every few panels and blow them out to keep them cool. Doesn't need a lot of pressure either.

Geez. Those are not the Lake Country CCS pads? From the picture they look like it to me. I have some CCS pads and they're definitely not my favorite. Thin Pro is what I end up using most of the time as well as Rupes yellow foam pads.

No they are not and I'm not planning on bashing them on this forum. The manufacturer or rather supplier no longer carries them and we can see why is all I can say.

Here's your pictures inserted to make them easier for all to see - but mostly me.

To me, the above looks like the pads got hot. It's normal for any liquid that you're using to migrate to the center of the pad and build-up on the backing plate.

WET PADS HOLD HEAT IN BETTER THAN DRY PADS

This is why I practice and preach to switch to a a clean DRY pad often when using foam pads on any tool.

The oscillation and rotation action of any brand of polisher is a,

VIOLENT ACTION


Heck, I'm surprised pads hold up as well as they do.


We collectively punish our pads and all their different aspects, the backing, the adhesive and the foam itself, anytime we buff out a car.


Just what I see....


:cheers:
 
Totally agree Mike and I should have known better but I wasn't focused on the task as I normally am. It was however a first of its kind and I started out with rotary tools and those steering wheel size pads. .. Mike any videos of you doing a class from those days before DA pads were a thing?

Copy that. I think I remember wool pads as large as 9", maybe larger!

Nope.

My first real video included a dual action polisher, the Porter Cable. First full length video ever made showing from start to finish and the complete process.

Yep gotta adjust my old tried and true method now

But you stated you weren't using Speed 6, but using Speed 5, correct?

Sorry to sound like a sceptic, and not having further technical data to extrapolate what actually occurred (OPM-Pad in use, technique, speed of Rotation-etc) as such a failure is not being done and compared under controlled test conditions.

One would think and hope that a Backing Plate, and in particular, the Griots Plate which has a boatload of holes punched through it would be much more durable than any Pad attached to it. Yet the Pad didn't fail, the Plate did.

To more accurately state what failed in your particular case, is the Adhesive holding the Velcro Attachment Pad failed and separated due to heat. My question is then, does one single central hole in a Polishing Pad be the sole cause of such a failure? And that this is the culprit to blame for the failure?

How come then, I've not recalled any such failures happening to a conventional LC Yellow Urethane Backing Plate that possesses no holes for cooling, and that there's people out there who'll buff out, or should I say "try" to buff out an entire vehicle with one Pad, literally destroy the Pad in the process, but yet the Backing Plate goes merrily along for the ride with no damage incurred?

Not to mention other design features to enhance cooling with these newfangled Griots Machines, something's just not jiving with me with this one as placing any faults upon Pads, or user error.

I'll assume Griots, and other manufacturer's reasonings for placing holes in the Backing Plate is more likely there to help a Pad remain cooler, correct? That the Pad is the part that is the weak link, no?

It doesn't dismiss in my eyes why the Machine itself had gotten very hot, and in so short a time? And in which way the heat then traveled, from the Pad to the Plate to cause the damage, or originate from the Machine itself?

Were there any other anomalies you noted while in operation, any excessive noise(s), vibration, etc?
 
I can of course cite many other factors, but such will take on a more cynical vibe, and would be frowned upon here.

About all that can further be said, is to keep us all posted with future uses with your machine. I am apprehensive to comfortably say that a machine such as this apparently needs to be coddled to get by and get the job done.

I really appreciate the time and thought you took with this.

It was at spd 5 with a lake country MF pad with CarPro’s clear cut when the heat was coming up. I’m not sure what OPMs are at spd 5, but it’s stated at spd 6 to be 5300.

I’m still a little reserved on the machine, I want it to blow me away! Not blow away my pads, so first time use left a lot to be desired.
 
Looking at the into literature of these new Boss Machines, I see mention of either a 6", or optional 5" Backing Plate for the G21.

Yet, combing AG's site, I see no listing anywhere for the 5" Plate? Is such only available through Griots, or did this smaller Plate not come to market?

Which Plate was it that you had?

Please keep us posted with further updates when you can.

(BTW, I own a first version Boss G15)
 
I'll add this comment. Griots, if speed 5 or 6 is too powerful then you shouldn't have designed the product with those speed settings because the world is full of Tim "the tool man" Taylor type people who full bore is all they know.

Hey Rod,

Thanks for chiming in.

I know I speak for everyone else when I say it means a LOT and builds good faith and trust when a Representitive from any of our vendors actively participates on this forum.


Thank you.
