Who's actually used a Dynabrade Dual-Action Buffing Head

Kevin Brown said:
It's great... Get it!



Three good threads about it:



Had the opportunity to try a few machines - Car Care Forums: Meguiar's Online



TO flex or not to flex that is the question - Car Care Forums: Meguiar's Online



Dynabrade Rotary converter - Car Care Forums: Meguiar's Online



From one post I made:



Jason Rose and I were product-testing yesterday and he used the attachment several times, with great success.

Dynabrade #61374 Random Orbital Head Kit



Converts Standard Rotary Tool to a Random Orbital Polisher!

For mounting to tool motors up to 3,200 RPM.

5/8"-11 Female Thread

Kit Includes:



Random Orbital Polishing Head (patent pending)

50855 Hook-Face Backing Pad, 7" (178 mm) diameter

90082 Natural Sheepskin Polishing Pad, 7" (178 mm) diameter

50679 Wrench, 26 mm



He also used a long-throw, air-powered random-orbital.

A Dynabrade Dynabuffer #10240 (which I cannot seem to locate online info).

It's random-orbital with a 12mm diameter throw, double-counterbalanced, gear-driven machine.



I just called to ask him which was more comfortable, and he said by far the rotary attachment (Especially during extended use)!

This is exactly what Mike Stoops observed (posted in the linked write-up).

Both of them worked well.



The Dynabrade is a great choice. Keep in mind that it is designed for use with 8" pads from the factory.

The backing plate can be removed and a smaller one can be installed, though. PorscheGuy997 did this.

Sold. This is the route I'm gonna take. Now to find a place that sells them at a decent price.



The part number for the dynabrade rotary attachment is: 61379



Edit: I really need to learn to read threads all the way through:

And $82.65 is cheaper than $120. Isn't this what you are talking about Scott?



Dynabrade 61379 - Dual-Action Buffing Head

blk45 has already found the cheapest price on the DynaBrade. Thank you, sir! :getdown



Or maybe we could start some sort of Autopia group buy and support one of our own vendors here?



I do have one concern about this attachment, though. Our rotaries were not designed or built to take such vibrations. I hope our gear boxes can take it.

Try these guys... My friends and I have purchased thousands of dollars worth of tools from them:

Dynabrade 61384 Dual-Action Buffing Head Order#DYN61384 www.TheToolWarehouse.Net



From what I know, you want the #61379 or #61384.

These models allow you to switch from random-orbital (like the Meguiar's G110) to forced rotation/fixed orbit (like the Flex).



Even though their flyers state that the head switches from random-orbital to rotary, it is NOT rotary because it still oscillates like a random-orbital.

It is a forced drive like the Flex.



The original models #61374 did not let you switch- it was just random-orbital (like the Meguiar's G110).

Kevin, Have you ever used one of these with a lightweight rotary like the flex 3403?
Click to expand...



No, I have not.

I, too, wonder how the balance would feel if used on a lightweight machine versus a heavier one.



For instance, the Flex 3403 or the Metabo PE 12-175 versus a DeWalt DW849?

No problem! Glad to help.



I'm curious though.....do you want this in anticipation of the Kevin Brown method? I've been trying not to speculate and just wait for the write up, but from what I gather, I think it is "better" for the pad to rotate a small amount. I think the oscillation is more important. This is where a PC comes into play, because you can bog it down with pressure. The Flex and the Dynabrade setup wouldn't bog down from the pressure like the PC.



Hopefully KB can clarify this for us.

Well, good point.

In terms of rotation, I don't necessarily think that pad rotation is a bad thing.

When removing heavier defects with a random-orbital such as the Porter Cable 7424/Meguiar's G110/UDM, we want a lot of rotation.



For final finishing, we want the pad to rotate only so that it will not stall or flat-spot on a curve. If the pad stops rotating, that particular area of the pad would fill with abraded paint quickly. Some paints will cause noticeable marring of the surface when too much is present.



Since the random-orbital polishers listed above have the same orbit-size (5/16"), they all react about the same if set to the same speed setting. The Dynabrade utilizes a 3/4" orbit-size, so its movement is not as affected when added downward pressure is applied.



The recommendations made in the past relating to pad rotation are only a guideline to help the user determine if too much pressure is being applied (for a given liquid, pad, and pressure combination). Unfortunately, it is only a guide because there are a dozen more variable that can affect pad movement (type of paint, humidity, amount of liquid being used, condition of paint, etc.)



So, just as the popular machines take getting used to, so to would the Dynabrade. I think there are many advantages to the Dynabrade attachment. As a whole on autopia, we simply do not have a lot of experience using this attachment. The quicker some of us get ahold of the unit and start using it, the more information can be shared so a general 'plan of attack' can be formed.

Good point... I'm definitely ordering one soon just to play with it this spring/summer

Yup, that's it exactly. But I do have to wonder about my poor little Flex 3403's gear box. Flex's, regardless of the model, just generally seem to be more frail and subject to failure than other machines, especially when compared to the Makita 9227.



My 3403's gear box is just over a year old now, and it's making more noise than it should. :nervous2: Making it vibrate like crazy by adding a Dynabrade to it can't help. But then again, if it *does* fail, it gives me a perfect excuse for getting that Makita I've always wanted. :D

Sounds like a plan! :D
 
Well, I tried to order and use one...



I ordered it on 4/12 and it is not here! They must not stock at SJ Discounts, and they did not answer that question when I asked. Just told me that they are checking on the tracking number. I have been given about 3 different shipping dates, but with no real explaination about why it is taking this long. My friend in Canada ordered one to Vermont a week after I did and received it weeks ago.



Anyone have another source that can ship within a week?



Thanks, Rob Regan

After some discussion with Jason Rose and Kevin Brown at SEMA, I'm going to order one pronto. The best deal is here Dynabrade 61384 Dual-Action Buffing Head



Cheers,

I'd love to have you order a pair of 'em so we could save a bit on shipping, but I have a feeling the DynaBrade would make short work of my Flex 3403 gear box. Guess I'll look around and see if anyone would want to trade my 3403 for their 9227.



Anxious to hear your thoughts on the DynaBrade, Greg. You could always break it in by coming down and polishing the Chawjuh for me. ;)
