I think you are getting interesting answers to possibly the wrong question.
You don't need to get rid of rust what you need to answer is how do I
restore old machinery? This may or may not involve de-rusting. but if it
does you will still need to restore dimensions surfaces etc.
The answer to that is there are companies who can supply specialist polymer
based products for this and I will give you details off forum to avoid
advertising etc.

Thanks Dave,

I never would have thought of that process. What I have is a relatively old
piece of equipment needing resurection. It consists of linear bearings, and
their rusted surfaces, that may be reproduced if the rust removal process is
not effective. These bearings are not available from my local King bearing
dealer or anywhere else I can find.

The big thing in all this is a valve body with multiple openings that are
fairly precise. It's kind of like those found in automatic transmissions.
The body needs to function nearly as original and I'm trying to weigh the
cost of attempting to do the rust removal process or making a new one.

Also, I can't remember all I forgot about electroforming but for using the
process in the early '70" to make precise aluminum parts, that were gold
vacuum deposited for night vision device amplifiers. Could electroforming be
used on steel, when an acid rust removal process has been used, to restore
its original condition. Long shot, I'm sure.

Earl
