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

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

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?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.

DanFeed back please
