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

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.

yabbut, yabbut...there is hardly any mass. Where is the energy to penetrate anything going to come from?

At the risk of beating this to death, I remain

What? No cup/codpiece? Don't you know what is really important?

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.

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.

Andy -

In my OP, I noted that I'd be using board buddies as hold down/hold in/kickback protection... This would solve the issue you've raised..

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.
