268260 John Ruth <johnrruth@h...> 2019‑04‑08 De-Rusting Tools with Hidden Springs
GG’s

Last Tuesday’s morning Flea Mkt. yielded a seriously-rusted Starrett 140 10”
hacksaw frame.  Note well that this is NOT the current Starrett 140 with the
closed D-Handle, but rather an old straight-handle hacksaw frame.

The blade attachment points have a clever spring-loaded lock to prevent the
blade from becoming dislodged.

The spring-loaded plungers are free to move, and work perfectly. The exposed
parts of the attachment points are rusty.

My question for the Porch is “how to de-rust the frame and the attachment points
without killing the internal springs, which are captive inside a riveted
housing.

Electrolyzing springs yields “things that go “snick” in the night.” (TM of some
unknown Porch dweller.)

Either Citric or Phosphoric Acid would imperil the springs...

Unless the Porch can come up with an idea, I think it will have to be done with
a tiny wire wheel.

John, I would suggest Evapo-Rust. Alleged to work only on the rust form of
the iron molecule.  I’ve used it quite a bit, but only with things that are
exposed, so as they say, YMMV.

Good luck!

John,

For de-rusting I like the Klingspor abrasive blocks.  Firm rubber with embedded
abrasive particles. IIRC they call them hand blocks or abrasers. They can be cut
to shapes as needed with a utility knife to get into tight spots.  It might
allow you to leave the wire wheel for just the tightest of spots.

Kevin beat me to my standard answer.  I hardly use liquid anymore.

I like that the blocks clean without polishing. They don't leave shiny edges
like steel wool. The block with the medium grit abrasive seems match the
machined factory finish on old Stanley planes. Also great for cleaning up grimy
irons and chipbreakers.

John

Evapo-Rust has been hit or miss for me. Sometimes it works great.
Other times within a day or two the part has a thin layer of rust on
it. The faq section of their website says:

... "It is important to always rinse the metal after a treatment with
Evapo-Rust. Tiny molecules of iron will still be embedded in the
Evapo-Rust solution, and these molecules must be rinsed off with water
or they will activate the re-formation of rust on the metal object."

I'm a user, not a collector. Brass brushes for the heavy stuff. Rubber
sanding blocks for the lighter stuff. Evapo-Rust for the complicated
shape stuff. Call it patina and live with it for everything else.

Thanks,
Chris

Hey thanks for the tip on the abrasive blocks guys!
  You know me, I have to try everything. :)

Scrape first is my standard these days. Learn to use razor blade and 
other scrapers and
the whole tool restoration world gets easier.

   Also, nickel or chrome parts (since this is a hacksaw frame) do best 
scrubbed with Bar Keepers Friend and a scrub pad. rinse and blot dry.

Its acidic but pretty wimpy and seldom hurts. It leaves your plating as 
best as it can be.
The mechanic tool collectors all use it.
   yours Scott

Scott,

Be cautious with Barkeepers Friend (BKF). It contains Oxalic Acid, which in
small amounts can trigger kidney stones and in larger amounts is an irreversible
kidney poison.

The dust can injure your corneas, although I think that is reversible.

BTW: I use Barkeeper’s Friend frequently!  

Best and Most Repectful Regards,
John Ruth

Thanks for the warning. I use it in the kitchen, and heard it could be useful
for water spots on wood.
I have never used it in the shop other wise

The “Wood Bleach” you find in stores is usually oxalic acid as well.

268277 Mike Rock <mikerock@m...> 2019‑04‑09 Re: De-Rusting Tools with Hidden Springs Oxalic acid
We now use oxalic acid to treat for Varroa mites in our bee hives. 
Either vaporize with a heater or mixed with glycerine on blue shop 
towels, laid on the top bars of the brood area.
It kills off the mites and not the bees.  Oxalic acid is common in 
nature.....rhubarb for one place.

not to take it too off topic, but why mix with glycerine?  do the bees
ingest?
