Dynabrade 61318 Locking Random/Rotary Orbital Head Assembly

Thanks! Looks pretty similar to its bigger brother with the locking pin, but having the counterweight actually molded onto the spindle assembly top plate is kinda different.

I'm having trouble seeing the unit Tom. Please send it to me for closer inspection.I'll be glad to return it when I'm finished.

Paul, I ordered you one too, should be there anytime, go wait outside for it...

Any feedback on the new version, waiting to pull trigger, should I get new version or old?

I too am anxious to hear feedback on the new one, but the older one is definitely worth it.

That what it seems, and I too am waiting to hear about this new toy. Might have to just pick up a pair of the last ones.
 
Sorry guys, been busy working on the house and haven't had any time to try it out. I dont have anyone scheduled until March and both of my vehicles have coatings on them. I will see if I can borrow one of the neighbors cars to do some side by side testing. I can already tell you it's much lighter than the previous verson and a 5" pad is nice on it.
 
For the older dynabrade attachment users; Does the random orbital kit need the rotary's highest RPM's to provide optimal paint corrective ability!?





I just got the 61318 in. Was polishing down a hood with dewalt 849x with 3500rpm. OK, so After doing so, I immediately grabbed pc7424 and did a pass on the hood with STRONGER, FASTER paint correction. WHAT?



Now im thinking by looking at this device- is that it has to work well with a variable high speed grinder? Dammit, i knew i wasnt gonna be satisfied!



Opinions Plz

You're forgetting about the other factor than speed/OPMs: the stroke length. A PC/PCXP or similar have a 5/16" stroke. The older Dynabrade head has a 3/4" stroke. The new 61318 has a 3/8" stroke.



By the same token, I think the 3/8" stroke at a lower speed might allow you to finish down better (less DA haze) on super soft clears. That's probably why the new head locks into a true rotary mode, with the intent being you do the majority of correction in rotary mode, then switch to the DA for your final step(s).



So to get the same heavy correction ability out of a 3/8" stroke DA you'd probably need a higher OPM.



Just my best guess anyway.

Ok, yeah i get you,but the size of movement in my stroke wasnt my concern. It was pad rotation and strength.



I took another gag with an old(but good) makita grinder from a neighbr and the amount of correction i noticed made my night ,just making another machine to continuously invest in. AHhh

What do you mean by "my stroke"? Stroke length has nothing to do with the operator, it's the design of the tool itself.



Were you seeing the pad stalling out with your 849X?

Hmm.... what speed was the grinder spinning at?

I mean what you are saying i guess i just worded it wrong, not me the movement of the orbit yes.



And i had a 11000 rated. max suggested on 61318 is 12000 anyway
 
Anyone comment on if I should get the Dewalt 849x and Dynabrade or a new GG DA? I have a 7424 (original, non-XP), and it just is way too slow for me, and I use 4" LC Orange pads and M105... Just too dang slowwwwww.



Thinking of either getting a Griot's DA or a rotary and dynabrade....
 
I'm guessing this is going to spread material well but there's not going to be enough real action, movement between the pads and the paint, to get a lot of work done.



The action, when not in the locked mode, looks to be exactly what you get with a 3/16" throw air sander. But, since most people are going to put it on a polisher, max speed 3600 or so, and not a grinder, I'm thinking this going to about a third as effective as the air sander.



You can get an electric random orbital sander with that backing plate that'll do 12K or so opms for less money.



Like this one.



I'm glad to have people testing because I'm so skeptical, but even though I'm seriously skeptical, I could also be seriously WRONG.

I've been using the DB w/ a flex 3403 VRG (small/lightweight rotary) for about a month now. Using a Megs MF/Surbuf for compounding or white LC pad w/ 205 for a mid step or sometimes finishing. Have used a GG for at least the last year. No contest, game over...Get the DB with any rotary.
 
Just don't plan on using the DB (or at least the old one, not sure about the new one) with 4" pads.

Not so safe.
 
That original Dynabrade has some serious capability.



The new one (waiting on grinder order) seems to work great at high speed. The heat is not really transfered into the backing plate which is pretty amazing

The assembly head itself gets hot but not the hookit pad.



I have planned on demonstrating it on old integra hood>Which has been shot with rattlecan rustoleum straight enamel gloss black for fun. No bodyshop etiquette. Just piled coats with insufficeint flash and poor weather. Anyways it will be a great shot at what the new attachment can do for correction.
