news I have a bunch of street plate steel, that I want to magically
transform into welding tables.

They have rust on them, it is not horribly deep, but it needs to be
removed.

What is the most efficient way to do it using, say, a 9 inch angle
grinder. What abrasive things are best for it?

I am interested in the answers that will come. *For me, I would
investigate
the possibilities of some sort of acid wash, followed with power wash.
Don't know if it would be a good thing to maybe hook up a floor
polisher
with an abrasive pad, but I am thinking on staying away from the big
grinder
idea, and going for a method that would be very easy. *After that, I
would
maybe consider soaking it with cooking oil and heating it with
firewood,
just up to 350 F. to put a sealer on it. *Maybe others will suggest a
better
easier way.

After my last tangle with a grinder, I am not so fast to draw it out as
my
first choice, and that 9" can be a mofo if you mess up just a little..

MHO, will follow the thread and see what is suggested, at times I need
to
derust large areas, sometimes full lengths of 20 feet. *I would only
build a
bath for those if I was to get into a lot of it, but if I was moving
that
much tubing, I'd keep just new oiled stock in the racks.

I am a little leery of putting those plates in a fire, one is that the
village may not like it, and two, the plates may get warped.

Can you take them somewhere to be abrasive blasted inexpensively? I
agree with the caution on the angle grinder, the last time I used a 9" I
could barely move my arms for a few days after.

The way ig beats his effing meat on this ng, I'm sure he would have no
problem with a 15" angle grinder.
WhoTF would buy a 30" high welding table, anyway, besides a midget or a yogi
with a strong back????

But steve's floor sander/screens is a good idea. *A belt sander would also
do.

A belt sander is often used for imparting "grain" to metal. Gives a
nice finish. I use to program and machine a ton of face plates for
Krell who makes very expensive audio amplifiers and this is how they
were finished. Luckily we subbed out that job or I would have been
stuck doing that as well.
