Orbital That Can Do What a Rotary Can

I just when down and bought a Dynabrade polishing head random orbital kit for my rotary for $115.00 at my supplier.

Includes an 8� hook & loop backing pad, assorted wrenches, terry polishing pad which I’m not going to use. The machine can take ether wool or 8� foam pads. It says the power tool must never to exceed RPM rating of 3,200 RPMs. In a few days I will say something about it if anyone is interested how good it works? But looks like it can do much faster job then the PC can but my main concern is the quality of shine it can produce. One of my concerns is polishing the edges with it? When holding the rotary with it, it has a jerking back & forth motion while holding the rotary in the air. You have to have some strong hands to run it.

Here is a link to Dynabrade web site to the polishing head random orbital kit.

Definitely interested to hear your thoughts on it after you've used it. :woot2:

we we are all "Interested" so please post some info once you get going.





Accumulator:



It's no biggie, I'm never to proud to admit I'm wrong. I did find that link I was talking out.



It's BASFrefinish.com . You have to go to "resources" on the top menu, then from the drop down menu select OEM.



The PDF says 2003 so maybe AUDI changed up. So then we both can be right :)
 
Super- Yeah, please post your findings!



MorBid- That could be about the model years. I'll ask Stoddard's paint guy next time I'm giving him some business, gotta get some stuff spotted in on the MPV before too long anyhow.
 
I want to mention that it's very important to keep the backing plate tightened because if it's not, it will wear down the bearings. I didn't have the supplied wrench that came with the Dynabrade and I noticed it making a funny sound about a week ago and continued using it everyday and now it has to be replaced. I'm strictly talking about the backing plate head and not the main housing that this is attached to. I got transfered from a Chrysler location to a Chevy location at the dealership I work for, and began using this system and I'll probably never use a pc again. I've got to hunt down where I can purchase just the backing plate and not the whole assembly.

The diagram shows a through-hole mount rather than the DA standard stud mount or rotary standard screw mount.

Okay, that's it...I can't take it any more. I'm buying one. Believe it or not I was going to spend my day off manufacturing a contraption that would fasten my 2 PCs together so I could cut my polishing time down...but it would most certainly only be good for large, flat panels. But first I'll have to try this gizzmo.



Edit: It's done. Now I gotta get some "bulky" pads for this bad boy.
 
If it has an 8" backing plate, it must be perfect for standard 8.5" pads?



I have quite a few details lined up involving paint correction, so I'll be sure to post my results as soon as I get the unit, and some suitable pads.



Mark, do let me know if you are able to purchase the backing plate alone, as I may want an extra to shave down to 6"...we'll see.
 
Also, how big exactly is the backing plate? 7.5"? 8.0"? Will make a difference on whether I choose a 8" or 8.5" pad. Was think the Meguiars 8" yellow softbuff pad would work, as they are what I'd consider a "medium" firmness polishing pad...good for dual-action.

Very interesting add on device for rotary buffer. Please keep us inform.

Here's a shot of one with a Meg's 8" pad. I don't recall how much it may have hung over the edge of the velcro. (note: Dynabrade makes two versions of this thing, the one pictured is "the other one". Not sure why they make them different but they use the same backing plate.)

I use this on my Makita 9227 and I can get 95% of all paint defects out with a yellow Lake Country pad and a 1200-1500 grit compound. The thing I love is very little splatter and no swirls. I use this machine at the dealership on almost all cars and the results speak for themselves. I own a pc, Dewalt 443, and Cyclo and this current setup is the best by far. I do sometimes have to use the rotary, but very seldom.

Excellent post!!! This is why it all works, need to know more?
 
Mark said it measures 6.5". Borderline...but I guess the 8" pads won't have too much overhang. Using a little cuation, I should then be able to use some of the pads I currently have which approach 7". I might even be tempted to shave the pad down 1/2" so I can safely use all my current pads. I wonder if any of those 7" Propel/AB pads can still be found anywhere?
 
I got it already. And fortunately enough, I have a compound and polish job tomorrow on a black Honda...this oughta allow me to test the unit sufficiently.



The backing plate might be 7" in diameter, but the velcro is only about 6"...kinda shaped like the old-school backing plates everybody used in the 80's and early 90s - not the best design. A candidate for shaving down for sure. As is, the Meguiarss 8" pads are probably the best. I might also try the Sam Arnold 8" pads...though I don't own any.
 
I've never been a big fan of the concave pads on the PC. I just polished a panel on my Landcruiser and I'd don't forsee splatter being an issue...now that I think about it, I've never had any splatter with a DA polisher.



Don't yet know how aggressive the unit is, as my Landcruiser is already swirl-free. BUT, it has a huge throw so I can't imagine it not being quite a bit more effective than the PC - it better be, as it is a heavy and thus a tad unwieldy.



Mark, did the backing plate evenually come loose on you...or do you think it was never tightened sufficiently? What I'm asking is...do I did to periodically check to make sure the backing plate is tight to the steel bearing piece?



Thanks.
 
What size is the pad that comes with the unit? I'm wondering if the backing plate gets shaved down wouldn't that effect the throw because of the counter weight?
 
The pad is just an 8" reg rotary backing plate pad, I suppose you can put a smaller backing plate on but I don’t why you would want to? The pad orbits and so does the Dynabrade, Dynabrade might hit something if something gets between the pad & the Dynabrade like a luggage rack or side mirror.



Other thing to look at is the weight of the rotary that you are using. When I first ran the Dynabrade kit at the supplier it was on a heavier rotary and when I took it to the shop and put it on my light weight Makita rotary it shook more then the heavier rotary did while running them in the air and not on a surface.

Just like the PC it oscillates but the Dynabrade kit oscillates much more of a radius and the pad doesn’t spin at all. At its radius of going back and forth creates shaking of the rotary that might create fatigue to the hands. Again I haven’t used it yet on a car so it’s all speculation of what it does or can do but I will soon write something real soon.
 
It shakes a bit more than the PC, but not so bad considering the length of the throw.



I guess larger pads = more surface area = quicker results! And you're not gonna bog this thing down. Will leave as is for a while...just ordered a few meguairs 8" yellow pads.
