Step one. Electrolysis tank. Pic related.

>>1441954
These farrier’s nippers looked about like your hawk head before they went in the tank.

>>1441955
Wouldn't it be better to let them soak in a bath of oil for a while?

>>1441956
Clean all the dirt and flaking rust off and into the tank it goes.

>>1441946
I did this a while back.

Evaporust works great. Electrolysis, as >>1441954 said, is also great but requires a bit more effort.

That just makes a mess. Oil is for protecting tools from rust. It doesn't do much after the rust already forms.

I guess I 'learned' on cast iron pans. I read articles on hipster cooking sites (serious eats mainly) and decided I needed one. Got a lodge, sanded it to a flat surface then reapplied seasoning. Then I started buying old rusty ones and trying out derusting strategies. Dump it in a vinerar / lemon / salt bath, throw it in a fire, wirebrush etc. Then I did a few bench vises which were the same basic principles. Strip the rust, strip the paint, repaint, reoil, good to go. For hand tools you get the added fun of working with wood and trying to get them to fit. I've had a few projects in that area, an old cant hook, a hatchet, shovels, things like that. Now I just finished a cast iron grinder and am almost done restoring a 60s Kitchenaid. It's pretty basic stuff and once you get your feet wet you'll find yourself looking for more. So I guess my advice would be to just start and learn as you got. Heads of axes and other hand tools are very tough and you can pretty much do whatever you want to remove the rust and not worry about it. Look up videos on youtube of guys leaving their rusty parts in acid for a year.


Also Electrolysis is cool and works well but it's not something you need to remove rust. Wirebrush and citric acids do wonders.

I've fixed couple of old rusty axe heads. It's very satisfying considering they are of such manifacturing quality you simply don't find anything like that anymore. Was very worth it.

Incorrect. A 75:25 mix of A/T Fluid to Acetone will get under the rust and pop it right off.

Vinegar is best for light and medium rust, electrolysis for the serious stuff. If the vinegar is hot or even warm it works wayyyyyy faster. Just wipe then black soot off with a rag. Vinegar also leaves a protective ox coating that takes the place of the rust but doesnt damage the metal. Often called "etching" in knifemaking circles idk what else its called. You will need some kind of etch or oil (ideally both) to protect the tool. If you leave bare steel in open air it will rust right over again.

I've resto'd a lot of old but not valueable pocket knives. Pic related has a vinegar etch. About 20 min in boiling but off-heat vinegar and a good but non-abrasive dish soap scrub. If you use scotch brite or anything like that it will take too much of the protective coating ofd.

Yeah bro, move the goal post then tell me I'm wrong. The guy wasn't saying an oil mix with a bunch of caustic shit thrown in, he said oil. Full stop. You DON'T want to 'let them soak in an oil bath' to remove rust. You just end up with oily, rusty tools.

terrific job. The knurl on the adjuster is beautiful.

Depends on what you mean by "restoration"
I clean up old tools and then use them. I replace cords when I need to and such

I dont waste my time repainting and prettying them up at all. Its fucking stupid because Im going to get the shit dirty again.

Acetone isn't caustic, and its only purpose is to thin the oil so it will work faster. Gasoline or Diesel fuel will do the same thing.

>>1443734
>Acetone isn't caustic
It is a solvent. It will corrode many things if you spill it on them. The definition of something that is caustic is anything that has a corrosive effect. Acetone is most certainly corrosive. It is by definition caustic. Both gasoline and Diesel are also classified as caustic. Why do you think they use them as cleaning agents? Especially when dealing with things covered in oil.

>thin the oil so it will work faster
While oil can make removing rust easier all it does is lubricate the rust so it comes off easier when you use something else to remove it. Sandpaper or a wire wheel for example. It and of itself it will not remove rust on its own. Its effectiveness also decreases as gets rust thicker as it has trouble penetrating the layers. Special purpose rust removers and electrolysis are much better options if they are available a suit the situation.

no, caustics and corrosives are two distinct classifications of material.

>no, caustics and corrosives are two distinct classifications of material.

Definition of caustic
1 : capable of destroying or eating away by chemical action : corrosive

https://www.merriam-webster.com/dictionary/caustic

>>1443809
Caustics eat away at materials because of their heavily Alkaline nature. Gasoline, Diesel and Acetone are all higher than pH of 5.

>>1443843
Sometimes the word caustic is used as a synonym for corrosive, but caustic refers only to strong bases, particularly alkalis, and not to acids, oxidizers, or other non-alkaline corrosives.

Set of Irwin wood chisels garage sale find
Paid $1us for a set of 3.
All were rusted
And the one inch chisel had been poorly sharpened. It also had a chipped edge maybe from being dropped
No before photos

That stone needs some work.

Electrlisys works wonders, and the old black patina often remains wich is great.

Whats a good paint to protect against rust after you've de-rusted your tools?

>>1445657
Tractor and implement.

>>1445657
phosphoric acid is great to work on rust, it leaves a barrier against rust and works great as a process before painting.

I use vinegar to make wood stain by tossing rusty scrap in for a few days. I often recover things I thought were too far gone because how well it works.

>>1441946
I restored an antique tractor seat to make a chair, all you really have to do is go over it with a fine sandblaster, then coat it in Rust-oleum.

>>1441946
I prefer to keep a great patina like that intact.
