I hadn't thought about that in years, thanks for the memories. I wish I had an old tube of that glue to put on my garage wall.

And if the boss made sure you used the paper to death, you warmed it up with a propane torch to peel it off without leaving little pieces of the paper stuck on the pad.

A couple of notes about the DAQ

Got my new DAQ delivered just now.

I doesn't come with an aluminum pad. It is molded foam with a vinyl surface (ND part#48626).

In the instructions, it says the lock ring is specifically for removing and replacing the pad. Nothing mentioned about a "grinder" mode.
Even if you were to run it with the lock ring locked, the rotation would be an orbit with no spin. Not a spin with no orbit.
Did this model used to have a "grinder" feature that it no longer has?

Still waiting on the delivery of my IR palm.

The DAQ is a sander.
The "grinder" is a DCQ.
The DCQ is what I use, it's 5" and spins only,
there's no lock ring on it.

The DAQ works as a grinder the pad is simply running in an orbit and not perfect circle. When it is unlocked it is an orbital sander in that it isn't following a particular pattern, with different orbits every time it rotates.

The DAQ is most certainly a "Grinder" I have used it as such for years. I think the "removal of the pad" stuff is late coming or something. It makes no sense, what does locking that do to reomoving the pad, it isn't like it is locking the sander from rotating????

Product liability, why else? There is NO 'grinder mode', NEVER has been, it's for removing the pad.

Ever have the pad come zipping off in grinder mode? Just blip the trigger a few times and watch it fly.

Yes, babies must play.

Locking allows you to hold the head so you can unscrew the pad. Pretty simple.

Instructions:
"LOCK RING: The patented lock ring on the driving head is used to remove and replace the pad. Push the lock ring in at the "Push Lock" mark to lock the pad shaft to remove and replace the pad. Push the lock ring at "Push Unlock" after pad replacement. This permits the pad shaft to turn free for proper action."

LOLOLOL, then I have been using it wrong pretty effectively! That is funnier than hell, I am breaking my biggest rule, use the tool for what it is intended. I have never had the pad come off like that so I don't know, I have been doing this for 30+ years and never had an issue. I honestly remember it being marketed as a grinder too, hints the name "DA" Dual Action. Maybe it wasn't from the manufacturer but from the paint store or something, jeez I bought my first one 35 years ago I can't remember what I had for lunch yesterday!

The name Dual action is because it in DA mode it the pad has two orbits (the pad moves in two directions) circular and orbital,not dual use.....but we all used them as a grinders too but not for long ,they used a ton of air and didnt have much power in grinding mode...The hutchins is a DA sander but it cannot be set in grinding mode....Same with the IR I'm using and the mud hog..

I don't remember ever using my old ND as a "grinder" for grinding paint off or anything like that. Not that I remember that is. I have use it as a "grinder" with 120 or 180 on it while metal finishing (fixing dents with no filler what so ever) as shown in that link.

Just got my ND and tried it out last night. I noticed that it only required 40 to 60 PSI, where I always ran my Craftsman at 90. I didn't do a side by side comparison, but using 3M 80 grit, I didn't notice it cutting through the layers of paint any faster than the craftsman. However, I'm sure this thing is going to be the last DA I buy. Seems build very well, and I'm impressed with how quiet it is.

Next question: When stripping paint, what grit of paper and what brand do you use?

I'm working on a 68 Mustang that has two paint jobs on it. I plan on taking down to bare metal before hitting it with SPI epoxy.

with a da I'd use 40 grit. Much easier with a buffer with a pad. Any higher grit and you're wasting time. Rhino/ indasa is good and cheap.

I don't think that's right either. Try it at 90-110

Well you're right, that's what it says, but I'm
wondering if that's a typo.
All their air tools I looked at were 90 PSI.
that's the first air sander I've seen that low.
It also says 11 to 13 cfm, that seems high for
that low a PSI.
But if it's true, that would be a good sander for smaller compressors.
I have a Eaton 5 HP, which puts out more CFM than most 5 HP's
and it almost runs constant when I use one of my ND sanders.
Most of them a are about 15 CFM @ 90 PSI.

(I sent National Detroit a Email to confirm those no's)
