URGENT Wire wheel on TS??? Safe??? Issues??

Folks -

Santa's elf needs to distress some redwood for keepsake boxes, and doing it
with a wire wheel mounted on the lathe headstock to "sandblast" it seemed
like a good idea... but there are some hazards..

I got to thinking, could I mount the wire wheel on the tablesaw arbor, with
an appropriate zero or nearly zero clearance plate and "rip" my lengths of
stock with the wheel projecting say, 1/4" above the table? I have board
buddies to use for hold downs and I think I'd get a more consistent texture
on the boards.

If the wheel is covered by the board, I'm using board buddies to hold the
board firmly, and am wearing safety equipment, what might I be missing,
other than the grey matter that I've been after for years?

The wheel is rated for 6000 rpm, the arbor runs about 4,000. Does this seem
like an okay idea or will my last words be "hey y'all, watch this!"?

Sounds like Santa's Elf still has that problem with the eggnog.

You want to distress it, let a pack of kids play with it for a day.

Personally, I don't see "distressing" something new. I would
imagine the wood was pretty well distressed already, just by being cut
down. The Woodworking Gods agree.

If you want something to look "old", I'd say use old, used,
reclaimed, wood. Or, alternately, lay some new boards out in the open,
until they get weathered enough for you. But, IF I was going to do such
a horrible thing to an innocent piece of wood, I'd probably opt to use a
variable speed drill, maybe with a wire brush. If you want to use
paint, you can try wiping the wet paint with crumpled paper. Or,
hitting it some with sandpaper, when it's dry. A short google will turn
up all sorts of ways to do it.

My mind just can't quite grasp the reasoning behind "distressing"
projects. Yeah, I could do it, and probably well; actually, I've read
quite a bit about the different techniques used; but, I want whatever I
make to look nice; after all, it isn't an antique, so I don't want to
even try to make it look old. Over time it'll get beaten up a bit,
sure, but it'll have earned it's old look by then.

These things have a max speed rating. The grinder has a speed rating.
If A is greater than B, fine. If B is greater than A, don't do it.

Dunno. But I can relate seeing a piece of straw embedded half-way
through a living oak tree after a tornado, so I, personally, wouldn't
try the wire brush on a tablesaw. (If I've done my calcs correctly, 100mph
equates to 146 fps, so that 174 fps is pretty damn fast (circa 118mph)).

The hub on a 8" wire brush would be circa 5.5-6" in diameter (my 6" brush
has a 3.5" hub). Call it 130fps still in the 90+mph range.

I wouldn't use one on a table saw either, but that's because a drill motor
will do a better job most of the time and the bench grinder will also.
But... as to the dangers, well... pushing a piece of wood into a spinning
wire wheel on a table saw is not really any different than using the wire
wheel on a grinder. Directly under your hand would not be a good place for
a wire wheel. It's going to continually try to push the piece upwards. At
least on the table saw you have plenty of control by simply pushing down on
the workpiece.

You didn't mention push blocks. I don't think I'd want my hands too close to
that. Roll up your sleeves, too, and stand off to the side.

Make sure to blow the trunnions and adjusting mechanisms clean with compressed
air after you're finished. Those wire wheels tend to lose bristles at an
alarming rate.

Or maybe, "Here, hold my beer." :-)

Sounds ok to me, given enough safety precautions.

I have not even taken the wire cup out of the package, so THANK YOU for the
warning. I am actually using the angle grinder on a gun safe that I am
building and have had no complaints as of yet. Just by looking at the wire
cup I thinks to myself, this looks pretty tough, and put it back in the box.
The last I saw it it was still there. I really have no use for the wire cup.
But, with you post, I thinks me will look for another brand. Thanks

You're planning to do this on that sweet General tablesaw you were gloating
on last year? What did it ever do to p@$$ you off?

Just how many keepsake boxes was Santa's elf planning on doing, anyway?

I think I'd start with a wheel chucked into a tailed handheld drill motor.
The low angle grinder idea has appeal, but my DeWalt can be pretty
aggressive, and thrilling to control.

Maybe dig out that face shield that you're 'sposed to have for the lathe
work, too.

Patriarch,
wondering if John ran this idea by Rose first...

I'm not sure about the zero clearance plate. Wires tend to spread,
and what looked like sufficient clearance during setup may not be when
you get going.

John:

I'm not sure I'd want to put my table saw through such a thing, but that's
only me.

As an alternative, have you considered sandblasting? Even if you don't have
a rig, they can often be had inexpensively, or rented. Sandblasting is the
method used to make those nifty redwood "weathered" texture signs. Ofcourse
they now use a man-made board instead of the redwood, but they still
sandblast them.

Good luck.

Maximum 8" diam x pi x5000 /60/12 = 174 fps
The diameter of the hub is MUCH smaller than that.
Consider a mass , <1 gram.
What's it going to penetrate assuming it is flying in a perfectly linear
fashion? (Of course the eye-ball could possibly be bothered by something
like that, hence the face shield.) What are the odds of it flying off in

Could a wire wheel in a TS be any less safe than those moulding

With the safety precautions mentioned previously, I really see nothing
wrong with the concept. You can even set the depth of 'cut'. Age a

And yet.....why does it 'feel' wrong?

I am using reclaimed wood, it just isn't "old" yet... as for the pros and

Oh, I don't know. You just want to "beat up" the wood a bit, and,
as you say, redwood is pretty soft, so it shouldn't take a lot of
pressure.

I'm thinking you could make something pretty easy. All you want to
do is pick up some sand and blow it on to the wood. A couple of bent
piects of tubing should do that. Just stick the pickup end into a can
of sand, and reuse the sand. Or, you could get one of those el cheapo
little sand blaster nozzles for just a few bux.

Hmmm. Or set a vacuum to blow instead of suck. Stick a piece of
tubing over the end of the hose, with a hoe in it, then pour sand in the
hole.

Or, just find a sandbox, with a bunch of kids in it, and let them
play with the wood for a day.

That should have been "hole", not "hoe". Keys stick at times. Or,
you could dig a hole with the hoe, burry the wood, then redig the hole
with the hoe, to recover the wood.

Less than it is flying off my angle grinder wire brushes. Admittedly
they _do_ penetrate flesh. So long as the shaft speed doesn't exceed
rated wheel speed, then flung bristles aren't the problem.

I wouldn't use a wire wheel in a table saw, simply because it's an
awkward arrangement. When I use a wire wheel I like to have it
directly under my hand, not reaching over a couple of feet towards it.
Using it in a table saw would make it impossible to control the
downward force properly - unlike a sawblade a wire brush's force is
almost entirely tangential from the top surface, not the lower edge,
and so this is almost guaranteed to start throwing timber at you.


Makita make a tool specificallty for aging timber like this. It's a
large, wide, handheld drum / brush sander.

Yeah, they do that. These days I'm _very_ fussy about the brand of
wire wheel I use on the angle grinder. I recently heard
www.ohiobrush.com very highly recommended over in the welding ng.

For aging boards, I'd definitely use a hand-held grinder and move it
over the board. I wouldn't think of using it in a tablesaw - it's just
the wrong way to bring the two components together.

I'd also be inclined not to age the boards, but to make up the carcase
and then age that.

Dunno - what is the tangential velocity of an inch long steel
needle flying off a 5000RPM 8" diameter wire brush?

Just a word of caution.

I bought a sears angle grinder and a cup wire brush to clean up some metal.
It was a small job. Just smooth off some surface discoloration. Just enough
to make a dull surface shiny again, Not heavy rust or anything.

That Sears cup brush totally wore away. It not only threw bristles all over
the place but the bristles themselves wore down to the nub. I have used
makita before. They lasted at least twenty time longer than the Sears crap.
I paid $15 for a wire cup brush and it wore out completely in less than an
hour. My old makita brushes literally lasted for years and years of
occaisional use. I would say at least 60 hours. And they were still good for
many more hours.

I got the Sears angle grinder on a closeout and got a good price. I did not
expect to use it that much. I didn't know that I was going to pay far more
for supplies.

And the Sears angle grinder was harder to hold and control than the makita.
You get what you pay for. Not just in the original tool, but in the supplies
as well.

Before you start could you set up a video cam, Oh Just in case of course.
My opinion: Those wire wheels come apart awfully damn fast, I am constantly
cleaning up wire shards after using my bench grinder w/wire wheel. I do have
an angle grinder that has a wire wheel attachement with it, maybe that would
work for you. It's much safer. Got it at Martha Sears for about 30 bucks.
Good luck and keep that camera rolling cause its all real TV

How can a wire wheel in an (hand-held ?) angle grinder be safer than
in a table saw?
