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

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.

I know a welder with a table about that high if not a bit lower but the

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.

It depends on what the rust is like. But for rust as you describe, i
wire brush and then use citric or phosphoric acid. For wire
brushing, I use what I have. A regular 1/2 hp motor mounted in a yoke
on a thing with three casters and a flexible shaft. A large angle
grinder and a cup brush might be better.

EvapoRust is your friend :-). Depending on size and weight, maybe put down
a thick polyethylene dropcloth sheet on the floor, put a couple of bars down
to hold the sheets 1/4" off the floor, then put a sheet down, prop the edges
of the plastic up to form a pool, and pour in the evaporust so the metal is
submerged. Put another plastic sheet over it to limit evaporation and go
away for a day or three. Pick that sheet up, drain off all the evaporust
you can, go wash that sheet and put in the next steel sheet. Will take some
time but very little effort or labor. If you can arrange a "sump" to get
the liquid deep enough in one spot, put in a little pump of some kind to
keep the stuff flowing and it will work faster. Warm it up and it will work
even faster - got any 500W halogen work lites? Just shine them on the rusty
steel.

I kind of like the chemical idea, also, because it takes comparably

If you still have that Tenant floor machine, this might work.

You know that setting only works on liberals, don't you?

The list of settings from the user manual of the Anti-Liberal Phaser:

00: Saftey W/child proof lock to keep Liberals from hurting themselves.
01: Annoy
02: Irritate
03: Bug
04: Infuriate

Those brushes are rated at 3600rpm but will easily stay together at 1.5x
that. The best way is to stack single sections on a long arbor. We
swage multiple brushes on a tube for customers wanting a quick-change.

How large?

If you have the room and they will fit you could use an electrolytic
bath. I have one built from a water tank, Another one from a couple poly
drums. For you maybe something like the kiddy pools or the small
livestock tanks. They grab some PH+ chemical from a pool supply outfit (
soda ash, washing soda, sodium carbonate )

http://antique-engines.com/electrol.asp
http://www.instructables.com/id/Elec...val-aka-Magic/

You can basically make a tank out of anything that will hold water BUT
it cannot be metal unless you line it with something non-conductive.

I have done full car frames. You can do the interior using electrodes
with standoffs to keep them from grounding out. I used cheap foam.
Works great on things like motorcycle tanks as well.

I don't know about cost effectiveness. I tend to use a wire wheel on a
grinder. On flat surfaces, the cup wheel style works best for me. I
asked a Sait salesman once about it and he suggested a flap wheel
sanding disk on the grinder - it works, but sure seems like a lot more
time and effort. There are some of those 3m type fiber disks that I
have not tried.

I've got every reason to be negative in this group. This newsgroup is
no longer about metalworking. It's now a group filled with phony
conservatives like Wieber that have no interest in improving their
metalworking skill set.

It's hard to give a first choice because iggy is a worthless piece of
**** who as per usual he have left out very important details such as:

How many plates need to be done per month? Are all the plates the same
size? If not, what is the largest size plate that will need to be
prepped. Does he have the space for dip tanks? Does he have a place
outside or a room to safely sand blast in? Does he have other
applications that would justify sand blasting. How big is his
compressor? Does he have a fresh air respirator?

http://www.nortonsandblasting.com/nsbNova3hoodSale.html

Does he have a shop laborer who has time to run a sand blaster? Has he
called a 3M rep and asked them to stop by and make suggestions on
which product they recommend?

It's not about learning for iggy. It's about the cheapest price and
bragging. iggy is a worthless **** who's not capable of doing much
learning when it comes to metalworking because his ego gets in the
way. He's only interested in the lowest price on everything and can
never see the big picture.

size? If not, what is the largest size plate that will need to be
prepped. Does he have the space for dip tanks? Does he have a place
outside or a room to safely sand blast in? Does he have other
applications that would justify sand blasting. How big is his
compressor? Does he have a fresh air respirator?

Does he have a shop laborer who has time to run a sand blaster? Has he
called a 3M rep and asked them to stop by and make suggestions on
which product they recommend?


I have a hard time with your logic. Iggy has not presented enough
information to make a first choice, yet you can make a last choice.

Based on Iggy's previous posts, I would expect that he is thinking in
terms of three of four in a month and getting them clean enough to be
part of a welding table. And the size is what turns up so could be
from a couple of feet square to maybe as large as 4 by 10. So perfect
is not needed. Hardly worth setting up sand blaster and dip tanks
would just take a lot of room for not much use.

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 wonder if you could do it electrically? Say with a large piece of cloth saturated with PH Up from a swimming pool supply and a power supply. Pos side of the power supply hooked to a piece of sheetmetal, laid on top of the saturated cloth, and the neg side hooked to the plate. I do this with smaller parts in a bath often and it removes rust quite well, but slow
