Rust remover

Have you tried some penetrating oil first?

yeah, id suggest dumping the whole thing in penetrating oil and just letting it sit for a bit

After "some", try Kroil. Add heat to drive it in. From elsewhere:

SOP for seized anything:
-apply Kroil. Go away, come back tomorrow.
-apply Kroil, heat until the Kroil is just seething/bubbling/boiling out of the joint. I use a propane torch, a hairdryer won't cut it. You're boiling the Kroil into the joint.

If the Kroil won't do it, nothing will. Also, be very sure of your geometry. . . pins, shoulders, etc.

And after you've got it apart, thoroughly clean/soak in EvapoRust.
Won't remove anything but the rust

plain old white vinegar takes rust off and won't hurt the metal as long as you don't forget about it. The acetic acid reacts with the iron oxide and take the rust off the base metal. You can scrub it clean with a wire brush after an hour or so in the vinegar. Rinse well with clean water and you should be good to go. Protect the metal from further rust with a finish of some type, or spray it with some oil to protect bare metal until you're ready to finish it.

Congrats , always good to see a happy ending . You are well on your way now, please keep us updated on your progress. Good luck.

Dude, awesome. Keep up posted, let us know if it's a shooter or a hanger when you're done.

H&R The American

Hello everyone, so I found this old H&R The American double action in my parents attic that belonged to my great grandfather. I'm slowly but surely taking it apart, however the cylinder pin is broken and refusing to come out. I've tried tapping it out from the back without any luck. The cylinder and pin spin together, so my next step is soaking it in some rust remover. The gun is in rough shape and I worry the rust remover might ruin the metal of the gun, any information is greatly appreciated.

Thank you

Take a few more pictures. I may have a parts gun for that thing.

Good idea. It can come back to you in due time, but it may as well follow the family down.

If thats plated like some were vinegar will remove it. If it's just metal it works great.

Evaporust will remove rust nicely and even rust bluing. Leaves the metal in some areas black or dark gray but that buffs out nicely. I have an old axe head soaking in it right now. The best part is you don't necessarily need gloves and it doesn't smell.

Nothing is going to fix pitting, all you can do is get the grime and rust off to stop the deterioration.

Don't rush. If you think the muck is fouling, drop the HR in a can of Kroil, ATF+acetone, or just kerosine, mineral spirits, or diesel, and walk away for a week or two.

Evaporust does not attack the metal, several days soak will do a lot more than a dip.

PB BLASTER is the best rust dissolver and penetrant I've ever found. not sure is it's safe on gun finishes though.

this might be a long shot but try Hoppies #9 if all else fails

I would not use it directly on blued finishes. It is great for freeing stuck parts, though.

If it is nickel plated, soaking it for very long in Hoppe's #9 will strip the plating.

PB isn't as good as WD Penetrating Oil, by test. I was quite surprised reading those results. It's NOT ol WD40, it's part of their technician line. I have found you don't need to soak things in Evaporust for weeks, it either gets it done in 24 hours or it can't.

I now have cans of PB lying around I won't use while the WD Penetraiting runs out frequently. I am going to mix a highly recommended garage solution of acetone and Dexron 50/50 as that is by the same test far superior to them all. Quart of each in a gallon can you can seal and it's both quick and cheap. Take caution of any non metallic parts being exposed to the acetone and use the appropriate gloves resistant to it.

PB is pretty good, but it smells worse than Ballistol which is a real accomplishment.
