That's an awesome statement from someone who can't tell a buffer from a
grinder and uses the grinder to "buff hulls"...

No yard on the planet uses a buffer on a hull, Mooron, at least not one I've
ever seen. They use big grinders with polish wheels. Polishers don't get the
job done, except maybe on a new hull that hardly has any oxidation. I have no
doubt that you own a silly automotive polisher and some of that colored
New-Wax!

Bwahahahahahaaha!

Ha Ha Ha..... Man that statement really places you in the proper category of
an idiot when it comes to tools.

Tell us again what the RPM is of your "Professional Grade Grinder".....
then try and clue in as to why buffers might be different to grinders. Then
try and think why they call it a grinder and not a buffer.

Really Bob.... you're sounding dumber with each reply. Stop now before
you've made a complete Idiot of yourself!

Oh dear!

Get a proper polisher. They do the job just fine!

A toy B&D won't do the job, but a professional polisher will do a 32 footer
in an afternoon.

My club has a proper polisher, and I can testify that it gets the job done
in a fraction of the time.

But Bob claims all marinas use "Grinders"... big professional grade
grinders.

Grinders spin way to fast.

Good lord. My B&D Grinder is 3000-7000 RPM. A brand new Porter Cable POLSIHER #
7336SP is 2500-6000 RPM.
Unless your boat is pretty new, you'll be using the upper RPM ranges once you
know how to handle it. Some grinders do up to 10'000 rpm fixed with NO load,
and even that's fine with a big pad. It slows down a lot when applying
wax/compound. Even skilled autoshops will use them, though paint buring is a
risk.
Sorry, BOB CARROL. I actually own and use these tools, so you can't come in and
hope to make crap up.
BUSTED AGAIN!

Bob, I am a tinsmith and use these tools every day. A grinder has the lowest
speeds you state, and are way to fast for polishing, They also use a much
higher amperage draw than a polisher and will not slow as a polisher will
with pressure. They do not have a variable speed range and will burn
through any gell coat at their rated speeds, read the can a can of compound
from any reputible manufacturer such as 3M or Norton. I am not the one
busted here mister, I am the guy you see using these tools every day to
remove/clean up welds and prepare steel surfaces. If you wish to remove the
gel coat a grinder will work, but to polish, not with out an impossibly
light hand. Besides, read the owners manual and tell me you would polish
with a tool designed for "rapid stock removal with 80 to 100 grit paper and
swirl-free polishing with 120 to 150 grit paper" as stated in the manual on
page 7. These tools are for polishing metal to a high lustre, not for
cleaning up a GRP surface, unless of course you call removal of the gel coat
cleaning up. Go to http://www.porter-cable.com/index.asp for the manual. I
am sure that considering the rated amperage, 3.5 amps the tool you state
will slow enough to polish fine with a careful hand, but it is not a
professinoal grade grinder, it is a professional grade polisher, and
Poarer-Cables grinders use 7.3 to 15 amps and will not slow down enough for
GRP, a grinder is not for polishing a polisher or buffer is for polishing.

Yes, indeed, you ARE busted. My B&D Grinder and several other's I've seen ARE
VARIABLE. Some DO have variable speed. One of the Porter Cable units I used to
use was also variable. Mine goes down to 2500 RPM, though I use higher RPM
during jobs.

http://www.powertoolservices.com/too...on/6154-70.htm

Meanwhile 3M suggests a max RPM of 3000 RPM, but you can safely exceed that by
a good margin. We certainly haven't damaged any hulls using the B&D. Meanwhile
I've never used ANY grinder that didn't slow down quite a bit with a big polish
pad on it and under load.
Stop talking about stuff you don't know about. I actually work on boats every
year.

Great. I'll look for some steel surfaces on my boat and call you if I find any
that need work!

Bwahahahaha!

RB

These also run at those speeds, but I don't think you will polish with these
either http://www.porter-cable.com/index.asp?e=547&p=2809
