Made the 2" Electric Polisher!

art, another option to where you wouldn't have to cut the backing plate is to use the megs xtra-cut mf disc cut down to the 3" size to fit the supplied backing plate that it already comes with...

I believe Art was saying because of the oscillating motion of a DA, it causes more heat at the Velcro interface.

It's seems odd and can't really explain the physics of it. Michael Stoops mentioned this when I attend my first Meguiars 101 more than a year ago.

Still seems like it should be rotary generates more heat with a smaller backing plate.

Imagine a 3 inch rope with a ball

Imagine a 3 inch rope with a ball
tied to the end spinning fast. Now imagine the same setup and speed with a 7" rope and ball. Which one would you think would hit harder?

Now for a DA and a large backing plate. Since it is spinning randomly your not really concentrating all that energy in one area. But with a small bp, all that energy is being concentrated on one area.

So Rotary with large bp can create a lot of heat because of the force of the big plate going around in one big circle. Opposite of the DA and large backing plate.

Now Rotary and small backing plate, Since the size of the spin the energy is not being built up. Since it is in a small circle. But a DA with a small bp all that random energy is being concentrated in one small are.
Kevin Brown also said something about product build up and CC residue being concentrated in one small area with the DA and small bp.

Something like that. You can ask Mike Stoops next time you go to Meguiars. He'll explain it better.

Try it with the tip of your finger spinning it on your forearm. Large circles and small circles. Then large random circles and small random circles. Best I could do and since I have all these machines with different size bp's. I found this to be in fact true.
 
That's pretty kewl Art. I wouldn't be able to keep it level.
 
Next TNOG at Meguiar's is the 31st.

Bring that little puppy and we will get out Mike's FLEX PE14 rotary and the little pneumatic and do some experimenting!

IR temp gun
PTG
1500 grit sanding marks
Black Test Hood
Unlimited Supply of compound & polish

Now that's a Party!

Yeah I had that option, I also have 3" pads that I use either on my Rotary or PC. What I wanted was something smaller than a 3" which is why I bought the Griots GG3 and 2"s seems plenty, but who knows might create a 1" sometime in the future.

Also I think the GG2 (the name of my new DA :D ) will have plenty of correction power since this setup just keeps the pad spinning so we'll see.

Yeah for sure and we can test it out on the test panels. I was actually planning on going to that one too so see you there. I actually want to (if given permission) try and heat up the paint with my GG2 as much as possible to see where I should tread lightly when using it on customers cars and to see what it can and cant do.

Oh and thought of some more reasoning of Rotary 3" and my DA 2". I saw this first hand too. If you are using a Rotary type tool like a drill on paint, while it might not heat up as fast. It can (seen it done) create holograms on the paint. My client brought me a car that a drill/rotary was used on the hood and it had holograms and I had to take them out. So I guess a DA 2" or 3" has its place too. Like I say, it's just another tool in my Detailing tool box.

That is why I think Meguiar's came out where there own version of a DA that attaches to a drill. Meguiar's DA Power System.

What advantage do you see in using a drill with rotary action vs a dual-action polisher?
Click to expand...

Well the rotary action is much more stable and can get in tighter areas than a dual action throw. You gotta figure a 8mm throw in each direction with a DA, so that's 3 inches plus 16mm compared to just 3 inches with a rotary. Also if the area you are working has a pannel perpendicular to it, the rotary won't bump against that pannel.

Is the throw the total reach of the BP or the movement in any given direction?

Using a 5" BP (127mm) and a throw of 8mm. Is the area covered

127 +8

or

127 + 16 ?


I though the throw on a GG3 was 3/16" (4.76mm). Get out a micrometer and look at 4.76 mm...divide that by two...tiny "Jiggle".


To me that movement is virtually imperceptible and the trade off of the dual-action being that it is less likely to inflict holograms.
 
Update on my custom made electric 2" polisher:

Made it longer, so now I have the option of making it shorter or longer if I want.

I am thinking that 2 couplers should be plenty and not 3. (For now, but if I wanted I could make it 10 feet :laughing: )

I also want to try it out on a test panel, before putting it on actual vehicles, because I don't want to have any whoops moments and want to find out what this tool can or can't do.
 
That extension looks unsafe, unless it was one whole piece. I Dunn, I wouldn't want any if those small extensions coming apart and flying into the paint...
 
It still in the works and was thinking of somehow wrapping it in rubber somehow. Since all that metal looks unsafe period. Lol

Got the idea from Mike Phillips picture.

I have seen electrical tape and/or 3M vinyl paint tape used to cover the extensions.

I agree that it would be prudent


You know we are going to want.to see video. Get your Uncle to operate the camera.
 
How about covering the extensions with a length of small rubber tubing/pipe?
