Sander Question

[cuda_]

Whats the difference between a DA sander and an orbital esp. for body work?

[paint toad]

by orbital i assume you mean a palm sander....they are both DAs,just palm sanders have a smaller orbit and are meant for finish sanding

[94redSS]

just to add....if ur gonna start doing body work learn to used good old blocks first im in my 3rd year doing auto body as a perfession an am now just learning how to get the d/a bodywork trick down.....just my $ .02

Thanks guys, exactly the info I needed.

And just how evil is it to use a random orbital sander, instead of an air sander?

Like this one?


I don't have the access to air tools like I thought I was gonna, and I'm not doing finish work with it, either.

air sanders are for rookies

.....ur just like all the old farts at work im a fan on 36 on the long board when the filler is tackey enough to sand it

no...you are wrong....i do not like nor own an airfile......i use 36 on the longboard myself......or my 8" 'mudhog' (big da for those that don't know),depending on the situation,although any more,i don't do mudwork of that type.....back when i was paying my dues i used to have to save a shit load of panels because of tight asses....but i am fine with that,i would not be the bodyman i am today if not for that....

i try to not to put anything coarser than 80 grit on my long board anymore honestly...i am a painter,i shouldn't even own the tools...at my last job,all i took was my guns and my dynabrade.....

well DA is just dual action. exact same thing as a random orbital. it just means the disc itself spins as the whole thing moves around. DA is what it's called in the auto body world and are normally air powered. random orbital in the wood world and are electric.

Kewl, so I didn't really "need" to buy that DA sander a while ago. Now that i have that knowledge, I need to get some of the good epoxy spray primer from the paint shop, and I can start getting shit done.

[paint toad]

brian,i wouldn't recommend that,but i guess you could use it....it'll get the job done but it will be awkward using that on a vehicle i think

[Big_Bake]

yeah you might wanna find a round one. idk about using the one you pictured above. i have a porter cable random orbital here at the house. it uses the same size pads as my DA.

a DA is good for experienced body guys, but if your just starting out, a block will do more for you, especially on big panels that you are trying to get straight. it's takes way more experience to do good work with just a DA.

I'm doubting I'll keep my original bed, anyway. Worth a shot.

what are the specs on that thing you posted above. is it just an orbital, or random orbital? what size orbit as well?

[dngrous_dime]

1/4 sheet random orbital. Not sure which model exactly, I just know mine has the gel pad on the palm area.

[JSamsS10]

Ive been doing bodywork for around 4 years now and i still cant get the DA down pat i knock my filler down with a DA then finish with a block

that's the whole concept anyway

[optikal]

yea finishing bodywork with a da would make for one wavy mess

hmm guess it will work. i don't see how a square will spin very good. think of it as earth. it spins on it axis as it revolves around the sun. that's how a random orbital/DA work. most square sheets i've seen just vibrate around, but don't actually spin.

Not that it matters, but nobody answered your question. DA sander is an old term that is now stuck with orbital sanders, since there are no DA palm sanders. A real "Dual Action" sander, a National Detroit DAQ or one of the million copies, can be switched into a grinder by an adjustment above the pad. I doubt many people who own DA sanders even know about the feature, but now you know.
