Re: Dual Action Polisher G110v2

Just cut 1 prong off the cord than you only get half the voltage.

Maybe I can borrow yours to try it out and see if it works.

Re: Dual Action Polisher G110v2

Dropping to a smaller pad with a dimpled face will sort of cancel out the effects of the two features - a smaller pad generally increases cut but with a dimpled surface you lose surface area, meaning you lose cut.

I may stand corrected, but I think you may be mistaken. From what I understand more dimples = less surface area = more aggressive cut on a DA, with the opposite being true for a rotary. This is supported by Todd Helme in this post:

I hope I'm not out of line, I just wanted to know which is correct.

It may also have to do with the foam, if Lake County has harder foam than Meguiar's.

If you come over and pick it up personally you can barrow it.

Re: Dual Action Polisher G110v2

Michael, is the G110v2 only for 110 volts? or can it work on 220-240 volts as well or do we have to wait for the G220v2?

Many thanks. If it'll work on 220-240 volts then I might want to get one shipped over here.

Sometime after the first of the year we will be offering a G220v2 for international use. Otherwise, the G110v2 is a 110 volt only machine.

Well, yes and no. Lake Country contends that a flat face pad has too much surface area and can cause D/A polishers to bog down, which will reduce cut. While it is true that bogging down will reduce cut, that isn't always the fault of the pad. Foam construction, cell structure, etc all play a role in how much cut a pad will give. But all else being equal - pad diameter, foam construction, machine speed, downward pressure, etc - a flat face pad will provide more cut than a contoured face pad will simply because it has more surface area contact. This is why LC says that a contoured face pad will be less aggressive on a rotary than a flat face pad will - less surface area, less cut (again, all else being equal). This same basic rule applies to the D/A as well, unless the pad bogs down. But we just aren't seeing a lot of bogging down simply because of a flat face on the pad.

Keep in mind that this is a much different dynamic than that involved with pad size. A 4" pad vs a 6" pad will cut more on a D/A due to the fact that you're concentrating all the energy, all the throw, of the D/A in that small area. The same small pad will be less aggressive on a rotary because the outer diameter won't carry as much speed compared to the outer diameter on the larger pad. Speed is a primary factor of cut with a rotary. Don't be lead to believe that less surface area on a larger pad is the equal to using a smaller pad in general. The dynamics just aren't the same.

Re: Dual Action Polisher G110v2

^^So basically dimpled pads would take longer to remove defects due to less aggressiveness, right? For the same reasoning, would dimpled pads be "safer" for first time detailers with no experience because they create less heat?

[Michael Stoops]

Re: Dual Action Polisher G110v2

Heat isn't generally an issue when using a D/A. Generally. You may well generate less heat on a rotary since you definitely generate less cut.

But it is very important to keep in mind the idea of "everything else being equal", and rarely is that the case when comparing different brands. For example, the LC orange dimpled pad provides a more aggressive cut than does Meguiar's W8xxx series of yellow pads. That isn't because the LC pad has a contoured face - the foam construction is also different between these two pads.

A more fair comparison would be between Meguiar's W8207 Soft Buff 2.0 Polishing Pad and WDFP7 So1o "Diamond" Foam Polishing Pad: diameter is the same at 7", foam construction is identical, but the WDFP7 has a contoured face - in this case a diamond cut but dimples would yield essentially the same result - and the WDFP7 pad provides less aggressive cut than the W8207.





It's basic physics - more surface area, more cut. Everything else being equal. Of course you have to work within limits of the tool. Obviously a 15" diameter pad would have even more surface area, but you wouldn't really be able to run such a pad with a typical D/A.

Makes sense, thanks!

Thanks for the clarification. Will be eagerly awaiting the G220v2.

Re: Dual Action Polisher G110v2

the description for the v2 says it has a side port for changing the "brush" ? ive never used a rotary before so i am not framiliar with what this "brush" is...can someone explain ?

Brushes in an electric motor are the small bits that feed the electric power to the commutator (the part that sort of puts the whole rotation of the motor in motion to begin with). They're commonly more of a graphite like bar than what you normally envision when you think of a "brush", but that's what they're called. These eventually wear down under normal use but are an inexpensive, easily serviceable item. Provided the tool is designed such that a simple side port can be opened up, the brushes popped out and traded for new ones. Most professional rotary buffers have this feature, but right now Meguiar's G110v2 is the only one of the popular D/A tools on the market that does.

In the multiple image below you can see (well, sorta, it's a small picture!) how easy it is to replace the brushes in the G110v2 - a simple turn of the cap and the old brush pops out. They only go in one way so you can't mess it up.

Re: Dual Action Polisher G110v2

ahh okay i see now...how often do these brushes need to be replaced for the g110v2 (saying on average)...and where can you get them ?

[Michael Stoops]

Re: Dual Action Polisher G110v2

The G110v2 will ship with a second set of brushes, but you can pick them up at any tool repair facility and even some hardware stores.

We have had several G110v2 machines in use at Mannheim Auctions (they recondition literally millions of cars annually!!) and they've been running in excess of 400 hours each without a single failure. And when Mannheim runs a tool, it is in use literally all day long with almost no "off time". It's doubtful you would find any one, or any place, that stresses a tool more.

Re: Dual Action Polisher G110v2

thanks mike...good to know the durabilty of the v2...as mine is on its way

i just searched radio shack, and it seems they sell a bunch of them.

i've read up a few threads on "extension cord" issue with g110...there seems to be a lot of confusion with it, and if it could be put down in one simple statement, would it be..."the thicker the cord, the better" ?
