I currently have a "Tim Tayler Signature" (I know, wow!) RO sander. It
has a 2.4A motor and 12,500 orbits/minute. When I apply pressure the
sander slows down and/or stops completely. My first thought is I need
a more powerful motor. But looking at what's currently available,
other than the real expensive ones, most motors aren't even 2.4A. So
what's the deal, is it a feature that the motor slows to prevent me
from scratching my work? Is it a common problem among all RO sanders?
I have had no reliability problems with this sander so I need to
justify replacing it. Thanks.
Do not apply pressure. You should only let the weight of the sander do the
work. If the sander is not removing material fast enough for you may need
more aggressive paper or to move up in power to a right angle style ROS.
Second Leon's thinking. If you're bearing down so hard that the sander
struggles, you're probaly removing too much material anyway. Lighten up and
go to a heavier grit, e.g., start with 80 and progress to 120, 150, 180 etc.
Yeah, it takes a litle longer, but refinishing to remove those scratches
that only show up after the second coat is a real PITA, eh?
I've had two DeWalt sanders and have liked them both, esp. the rip & replace
As for replacing the sander, you never mentioned if it was round,
1/4 or 1/3 sheet ? Now depending on what/how big of a piece you are
sanding will determine what you get. I have all three sanders which I
use for both automotive and woodworking sanding projects. If you are
using the sander for small projects, the round or 1/4 sheet palm
sander would be fine. On the other hand, if you are doing table tops
or armoir's ( sp? ) then the bigger sander is the one to go with.
The one big kicker for me is how noisy the sander is, not so much how
big the motor is. Cheap sanders won't last as long and are REALLY
noisy, plus a better sander will vibrate less in your hands giving you
more control. If you do any amount of sanding at all it's worth it
to go more expensive and find a sander that's quiet. The one I have
at the moment that I LOVE is my Bosch. Compared to every other
sander I have used it's the least noisy.
As for it slowing down and stopping I would say that your brushes
may be getting a little worn, it may be time to replace your RO.
Unless you really like it and want to spend the money to have the
motor rebuilt. Most alternator/starter repair shops have the ability
to rebuild your motor. They will also re cut your stator winding
grooves and when you get it back it should be powerful as it was when
new. Now like someone else said, pull it apart and make sure it's not
a bushing or bearing that's gone. They don't last forever.
Hope this helps, good luck.

I'll echo this. We have several sanders on hand, including some cheap
ones received as gifts or bought for one-off projects, etc. Over the
years I've melted down several B&D or equivalent 1/2 sheet sanders,
all of which are made entirely of cheap plastic and quite literally
melt with use. Unless someone's given it to you, I'd avoid B&D,
Skill, etc. as next to useless (though they will sand a few items in
a pinch before failing).
Much higher on my list are consumer models from reputable tool
makers. Right now we have a Makita palm sander and a Bosch 5" RO
sander we've been using a lot on a remodel project and in some
furniture building. Both work well, are comfortable to use for longer
periods, and seem sturdy enough to last a while. I expect the same
goes for the Dewalt, PC, etc. brands at similar price points ($50 for
the palms, $100 for the RO, give or take).
If you're able to bog down the "Tim the Toolman" sander that easily,
I'd give it away before it melts and go buy something a step or two
better...it'll save you trouble in the near future.
Sanding is a total PITA, thus bigger is better IMHO.
I have a 6" Bosch that gets no respect.
Building a boat, I beat the crap out of it and it just comes back for more.
When it's time to replace it, will get another Bosch or maybe the 8" Fein.
There are both German, you can't go wrong with either one.
Hey Lew - have you ever used an 8" machine? If you have, ignore the rest of
what I have to say, but if you haven't then let me say that you won't want
to replace a 6" tool with an 8" tool. (intentionally leaving that wide
open...). I'd go with both in my inventory if I were you. 8" is great for
knocking down big stuff and for overall leveling, but it won't get in where
6" will and it gets unwieldy after a while.
Thanks for all the replies. It's a 5" round. Most of my jobs are
small, but I do wish I had a belt sander sometimes like when I was
trying to strip paint off of my porch (only about 100sq.ft). I was
using 80 or 50 grit but it still wasn't working. I apply as much
pressure as if I were doing it by hand, so I don't know if that's
excessive. The weight of the sander alone definitely is not enough
unless it's finishing work. Perhaps I need a belt sander instead of a
more powerful RO sander.

Iy you need more force, then you are probably using the wrong tool. A
5" sander IS definitely undersized for stripping paint from 100 sq.
ft. It is more suited for finish work, as you surmised. You're right
in thinking that a belt sander is more appropriate for this type of
You are asking a boy to do a man's job.
Use a chemical paint stripper to get rid of the heavy stuff followed by some
quality time with that baby (5") ROS equipped with some 40 grit paper.
The only reason I don't suggest 24 grit is because they don't make it for a
After it's cleaned up, follow up with some 80/100 grit before painting.
Unless you are skilled with a belt sander (Read that you have experience
destroying lots of things with a belt sander), forget it.
I do a lot of sanding.
The least used sanding tool I have is a belt sander.
Well, if his brushes are getting a little worn, they are acting like they
should. All brushes wear and motors don't run poorly because they start to
wear. It certainly is not a sign that he needs a new sander. Oh wait a
minute - my bad... of course, it *is* a reason for a new sander. I forgot
for a moment the line that goes "hey Hun, I need a new sander, this old POS
that I've been using is wearing out the brushes." Ok, so I can be a little
slow on the uptake sometimes...
