How much is the oscillation diameter?

I'm planning to get one for my rotary as well, my DA vibrates like hell!!

I think its 3/4 of an inch, certainly a great addition to a rotary buffer:props:

How did you feel about the weight of it? Overbearing by the end of the car on vertical panels? What about the vibrations?

I have what I would call some "Big Guns", as a man of 275 pounds weight was not so much an issue with me. However I'd say that there was a little more fatigue by the end of the job but nothing that I wouldn't get used to rather quickly.

As far as vibration goes there was no excessive vibration. It actually kind of reminds me of what I would think a single headed Cyclo would feel like. (something that I had been wishing for ever since owning my Cyclo.) Like the Cyclo this monster Makita DA feels very much balanced and vibration free.

My first polisher was a Cyclo which is a rather heavy machine in comparison to a PC so heavy is something that I got used to early on and considering that the Makita rotary was my second polisher I have never really gotten away from heavy.

Now I'd think that if you weigh closer to 100 pounds the weight may be an issue.

I really feel that this purchase is going to drastically change the potential for earning money detailing.
 
I think I'm getting one of this for sure!!

Thanks Dave, KB and others! :)

btw I hope backing plate can be changed(any model with fixed BP I need to stay away from?)
 
Sry for another post, but what kind of backing plates do we need to use with it?

I have various rotary backing plates but none for the DA(as I have a DeWalt DA that comes with a fixed BP!)
 
Sohail it takes any standard DA backing plate, 5/16 thread. Look at page 2 of this thread and KB has some great pics and descriptions with some mods to the plate that comes with the Dynabrade

Yep! I've already tested my Dynabrade with a variety of LC and Meguiar's DA backing plates, all seem to work flawlessly with the attachment.
 
^Thanks guys!

The cheapest I could find it was for $85!

btw I was analyzing what Kevin said regarding working on curves that lower speed(lower OPMs) and high arm speed is the key to achieving better polishing transition on curves. I'll definitely try out this technique on the curves of my car!

I'd like to hear whether others have tried this or not!? :confused:
 
Got my dynabrade orbital/rrotary polishing head!!

Don't have any DA polisher backing plates, so ordered this - D.A Adapter 5/8" X 11

Cant wait to try it for paint correction! (btw I just used it in the air to see the motion etc. and the 'rotary' mode is quite odd! I still prefer the true rotary motion!

but the DA mode rocks!! :D )
 
Its been awhile how about some long time user reviews on the dynabrade,I am considering one now since I already own a dewalt 849 rotary...and the Flex is $300.00 + this may or may not be the ticket!

DanFeed back please
 
Dan, just keep in mind that this isn't a forced rotation DA like the Flex is, it's a free floating spindle assembly just like the PC/G110v2/GG6. The major difference/advantage is that it has a 3/4" stroke length as opposed to all the other tools' 5/16" stroke.

Also keep in mind that the Dynabrade adapter is pretty much only good with large pads; it doesn't lend itself to anything smaller than about 5.5"

That said, I still highly recommend it if you have lots of heavy correction work to do; I have been getting awesome results with it on a number of different projects.

I believe you have the earlier model #61374,from what I've read this model operates in a random orbital motion only like the PC/G110v2/GG6 yet the new Dynabrade #61379 or 61384 has a button to allow you to switch from just RO to RO With Forced Orbit Rotation like the Flex 3401!

Dan
 
I have the model with the button and it operates as a random DA and as a rotary when the mode is changed , not a forced random orbital as a Flex 3401 does. Works great on large surface areas such as pick-up trucks,vans and rv's.
 
I still love my dynabrade, like 2o2 said, when you push the button its rotary. I also love mine for any large area. I use my Porter Cable now mainly for the smaller areas, (I also use smaller pads on the Porter Cable)

Incorrect. I have the 61384, which has the "switch" you're referring to. I also have a Flex 3401.

The rotary mode of the Dynabrade is just that - a rotary mode: the pad is offset from the rotational axis, but it's not really "orbiting" in the same sense as it would be with the Flex. Two totally different concepts IMO.

OK now I am confused I researched this deal pretty good so I thought,anyways will the Dynabrade offer as much paint correction ability or even more when comparing to the Flex 3401?

DanFeed back please
 
While I can't say for sure since I've never used either (I probably shouldn't say anything, but I will anyway) I would say the torque of each machine is similar, but how it is applied is different.

My guess is the Flex has just a smidgeon of an advantage. Those comments are based on what I've read about each of the two.

Then again, you should seek advice of someone who owns both.

If we're referring to the "DA" function of the Dynabrade as compared to the Flex, I'd give the Flex a slight (and I do mean slight) edge, simply because it is impossible to stop the pad from rotating no matter how you use it (buffing with the edge of a pad, tons of pressure, etc. won't affect its gear-driven forced rotation). With the Dynabrade, you can still stall the rotation if you get too off-axis with the pad or put ridiculous pressure on it.

As far as the Dynabrade in "rotary" mode, that's literally what you're getting; it turns the polisher back into a rotary, with the only difference being your pad is now off center as it rotates. This is meant mainly for convenience so you don't have to constantly remove and install the adapter every time you want to use the machine for a different task.
 
I agree! I too thought that since I'd be using a rotary polisher with dynabrade, it'll be comparable to flex 3401 when I'm compounding or finish polishing! But the pad still used to stop on curved surfaces and when under pressure(in DA mode), no matter how fast the rotary was going(rpm)!

Now when I have the flex 3401, the forced orbital makes more sense. While polishing for the first time with 3401, I felt that familiar traveling of the rotary polisher.

Polishing on edges and small areas is wayyy easier now. With dynabrade and rotary on DA mode, I had to constantly adjust the position on panels to ensure that the pad was rotating at all times + with a standard rotary polisher and dynabrade attachment, the whole setup can be really heavy LOL!

One good thing about dynabrade is, you can attach smaller backing plates on it and use 4" pads to work on thin areas!! I still use the dynabrade for that as I only have a rotary polisher with dynabrade and flex 3401(cant use flex on thin panels due to big BP). PC and megs da polishers can take smaller BPs.

Its great when you've wetsanded the panel and are compounding, you can simply switch to DA mode for finishing!! :D

It works great on large flat panels as stated, but I like flex while working on curves! My car has many of those curves on almost all the panels except the roof!!

And yes, dynabrade attachment does have great correctional ability!! I have compounded and finish polished many panels that I had wetsanded to remove orange peel, with dynabrade and it worked exceptionally great!! :D
