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.
