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.

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!

Nope.

Very true, I had a B&D Pirana, one of the first 12 volt models made. it
was
one of the best drills I have ever owned, had it stolen 8 years ago.

Hate to pop your balloon, Capt., but B&D did make some
professional-grade
tools a while back. They weren't cheap, and they were top-notch.
It's
only
been within the past decade that B&D went the cheap consumer tool
route.

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

I first bought an 11 HP Craftsman snow-thrower but the belt broke on the
first run, I called Sears and they said, "no problem, but there's a 2-week
wait for a new belt." Naturally the snow (the big one of '96) wouldn't
wait for Sears to cough up a belt, so I took it back and got a Honda. It's
been running ever since with no problems.

yep - changed the oil in the snowblower,


Let's hope it's not a Ryobi.

Hey Thom, I put a pulley on the end of mine, and use the drill to raise and
lower the mainsail. It also attaches easily to the rudder (with tiller
removed), and turns the rudder nicely; just need to remember that "Reverse"
really means "Starboard"

Hey Guys,

What in the hell are you doing to your boats that you are wering out
drills? Even Nutsy, with the 1/4 century old "Derelict" shouldn't be
drilling more than a dozen holes a year! Please enlighten me?

I have an inverter and have a dremel I use on 120 v. I have it because
of the flexible shaft and the case. If I use it to drill a 1/4" hole
it's to drill a pilot hole and enlarge it with an old fashion Hand Drill
(No batteries) I can't remember the last time I've used either one.

Why is a commercal drill necessary on one boat?

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!

You do realize don't you that that device is an inverter?

Like I said, if we need tips on the tin parts of our boats (Scotty?) I'll drop
you a line. Other than that I follow what I was taught by professionals who
work with GRP. After 9 years I've had nothing but good results and no damage,
EXCEPT for when I 1st practiced on a already-dead boat at the yard.

I said it could be adapted and I also listed a second unit that works out of
the box.
You lose.
