All the talk about Dual action and orbital, What is really best? Why is a orbital so different (other than speed control) than the old buffer/polisher

Dual action means that the disc not only spins but moves up, down and side to side. This not only broadens the throw (area covered) but allows heat to escape, slimming chances of burning the paint. A rotary such as the makita is crucial. The hi-speed and heat this creates softens the paint allowing deeper scratches to come out but usually can leave micro surface swirls behind. This is where the orbital comes in to follow. Changing the pad softness and finishing polish (no dust) you now can polish to a mirror finish. Boh are in my pro arsenal. For an orbital I use the Flex or Rupes Big Foot

They have different purposes. The old buffer/polisher works with grit or heat compounds and takes different stages of application depending on the condition of your paint or surface. Higher grid compounds and wool pads will leave buff marks that will later have to be removed with follow up steps to eliminate these what you'll see as swirl marks. Orbiters are more for home use to apply and remove wax or glazes evenly. This will give you the basic shine without swirl marks but it not good to remove any kind of scratches.

Depends really on what your ultimate goal is for what you are doing. Rotarys require some skill to master if you do not know what you are doing you can cause some serious damage even with a foam pad and polish. However, rotaries also have the ability to work much faster and remove more severe defects from the surface. You can get a flawless finish with a rotary with the correct pad and polish. Now, if you are new to polishing and sick of doing things by hand a DA polisher is the tool for you. If you get somthing like a porter cable or meguiars it is a non forced rotation. What this means is when too much pressure is applied the pad will stop rotating and just vibrate on the surface. DA's are great for getting flawless finishes on decent paint . They excel at removing swirls and light oxidation with NO buffer marks. If you need speed the rotary is the way to go. I have both the porter cable and makita. I prefer the rotary, but if you are just a hobbyist i recommend a DA polisher. They are safer and you will get a better finish if your skill level is low.

random orbit eliminates swirl marks in the polishing process. I also recommed the soft foam polishing pad that you can purchase at most auto supply stores. I purchased mine at NAPA. This maching is well balanced and put such a nice finish back on my 2006 Jaguar that many people thought I purchased a new car. Best of luck. (I tossed my old car polishing unit)

The simple answer is cost and effectiveness. I've used them both on my cars and 36' boat and would never use anything but the Makita to prep the finish to receive wax. Get a good quality liquid compound like 3M to prep the surface. It is worth the cost in time and quality.

Not positive, but I believe the diff is the internal mechanism. Aircat is the industry standard dual hammer/anvil approach; Nitrocat uses a dual clutch system instead. Some say Nitrocat is a small bit more powerful, but a bit slower. I bought the nitro for truck wheels and it is PHENOMENAL. Turns a bit slower than my old wrench, but not more than 1-2 seconds more on a lug nut. The amazing thing about this is its light weight, very low vibration, and never appearing to work hard. Large, rusted nuts seem to come off with the same (minimal) effort as small clean ones--it's a rather uncanny feeling if you are used to other air wrenches. Everything this thing does just feels effortless. And, if you use it commercially and it eventually needs a rebuild, they sell very low cost DIY refurb kits for both types. I don't think you can go wrong with either one.

The Orbit can be configured to perform a wide variety of optional functions using left, right and double click, and all three of those in combination with the command, control and option keys give you a wide range of commands. One I find useful in graphics is to move the cursor- or drag a line- in an unwavering straight line (horizontal or vertical), for example. Of course, if you need to draw freehand, nothing really beats a tablet.

maybe but i would go for the round orbital sander, the one for velcro discs. few dollars and a huge diference. sheet sanders are going obsolete and soon to be extinted, they also leave "curls" on the sanded surface.

Multiple options vs single options and longer loop times. I own both pedals and love them.

All disc sanders, rotary or random orbital, are almost always used at a very slight angle. Not flat on the piece. The orbital even when held flat has more pressure on one side, they are very difficult to control otherwise.

I've never used the Wally, but it seems like pretty much the same thing. The Wally adds a tempo knob and somewhat longer record time. In my opinion, the biggest drawback for BOTH pedals is the single-button approach. It pretty much makes the pedal useless for live performance. If you want to jam along with yourself at home, either would be great. The JamMan Express (unlike the Wally) will run on batteries, but it eats them so quickly that you really must buy a power supply--it doesn't come with one.

The random orbital sander is more or less a finishing sander mainly for wood or plastic. A disc sander used to reduce welds or heavy metal is a rather rough sander. If you were to use a random orbital sander to do more than remove paint from steel, you would be sanding for a long time.

You should go to the 3M site. While it doesn't specifically say orbital sander, it does mention grinding and sanding. They also have a question box so you can ask them directly. The link is http://solutions.3m.com/wps/portal/3M/en_US/3M-Safety-NA/Safety/Product-Catalog/~/Mold-and-Lead-Paint-Removal-Respirator?N=3294427651+3294529207+5927440&rt;=rud

THE QUESTION: IS THE PORTER CABLE 7424XP A DUAL ACTION POLISHER? The answer is YES! You should check out either Pinnacle or Wolfgang for a great description of this polisher. Then on the same page check out the item HOW TO PROPERLY USE THE PORTABLE 7424 DUAL ACTION POLISHER. You can review the DVD on line and /or purchase the DVD for $12.99. The DVD walks you through the mechanics of a "dual action" polisher, how to prepare your buffing disc for the first time use, the use of different buffing disc, the proper way to apply your compound of choice and the proper way to buff your vehicle. As I recall, it is about 25 minutes of instruction. What is left? Just for you to use you new buffer following the instructions and gaining your own practical experience!

No do not it will burn the paint you need a random orbital type.This ONE IS TOO FAST too many rpms and only one direction will cause swirls ! A random orbital is mush slower and rotates in one direction! It only takes me about 40 min to do my whole truck,put the wax on a clean washed finish and then take it off with the orbital.Do get the one with the highest amperage thou.Generaly the higher amps cost a little more but it will last nuch longer than a lower amp rated one.Been doing vehicles for many years .Jack

Sorry, can't say. Have only used it as a buffer/ polisher for that it is great!

It's not orbital, I believe. I doubt it is stroke adjustable. To be sure, check with an authorized service technician. It is very solid hardware.

Jerry, do you know exactly what is wobbling? The P-C 7346 is a random orbit sander/polisher and has a high speed wobble by design. If your using the hook & loop pad system the pad must be centered as close to center as possible or a wobble will be created also. You might want to check the rotating concentric for tightness...Bob

It doesn't & that has confused me as well. I don't know why they used orbital. Maybe referringto its flexibility. Essentially - it is a really nice jigsaw. If that is what you're looking for-this is your tool.

The dual waver is nice. It's essentially 2 hair dos in one. U can do tighter waves or looser ones. That's y I picked this waver over the other one. And u wouldn't think there'd be much difference in the two waves u can use, but there really is!

M105 ULTRA is by far the most cut i ever used by machine, if you have heavy defects and need deep correction, use this with M205 as your finishing step, this alone will leave some light holograms, i always use M105 using a cutting disk (orange) or (yellow) pad depending on defects, then follow with M205 using a white pad, i use a flex machine dual action orbital polisher, look at some DIY videos on these two steps before starting your project, hope that helps.
