Go ahead, but first stop and think how much an emergency room visit runs
these days. Metal has to be clamped solid before you even think about
cutting it. Most wood saws have no useful means of clamping angle iron
unless you call those plastic or pot-metal things on the fence clamps.
If your blade snags the angle and it flips away from the fence, there
will be blood and broken parts. Your saw might be damaged too.

I want to put an abrasive metal-cutting wheel on a miter saw, to cut
mild steel angle with. Most of this will be 3/32" or 1/8" 1-inch angle.
Some say, "sure, no problem!" while others say, "the horror, the
horror..." The purpose is to cut a few pieces for some welding
projects. For example, cutting some angle steel at 45 degrees to make a
table top.

Now, before this goes any further, please do *NOT* tell me to "go buy a
chop saw" or "buy a used band saw" or whatever. I'm talking about a
miter saw ONLY, OK?

There are supposed to be two main issues with doing this:

First, it overloads the motor. But I don't think this would happen, if
you just use very light pressure and take your time and go slow.

Second, the shavings/sparks can damage the fence and/or the motor
mechanism (bearings). There may be some truth here. The fence shouldn't
be a problem, and I can always cover it with something. Particles? Some
suggest removing the vacuum. How about attaching the nozzle of my shop
vac just behind the blade and letting it catch them? Or maybe putting a
big magnet there, perhaps.

This isn't something I'll be doing often. Maybe once a month I'll make
3 or 4 cuts, at the most, no more. As I said, 99% is going to be
cutting 45 degree ends in 1/8" X 1" angle, so I can join them together
to make a square corner. That's it.

I use an abrasive blade in my circular saw for straight cuts, but it's
hard to cut accurate angles with it. I also have a Porter-Cable Tiger
sawzall, I don't think that would work well for this kind of cutting,
although I've never tried it.

Please give me a tip here, especially if you've actually done it, and
aren't just repeating what you've read or heard. And PLEASE don't tell
me to "go buy a chop saw"!!!

Thanks,
