Homemade Penetrating Oil

[doubleboost]

Not really a oil
But Acetyline and Oxygen always works
Diesel fuel is as good as anything i have used

John - are you talking about heating the nut/bolt with a torch to loosen it or cutting it off with a gas axe

Heating normally works
The cutting is always an option
On really sized stuff heat is the only thing i have ever seen that works

Some guys use wax on a hot bolt. Talk about sealing it up...

But that is what makes electrolytic removal so appealing to me - it actually removes the rust and puts it in a rag. Maybe a drop of Evaporust? I await a rusty bolt.

I started using the Acetone/ATF mix about 20 years ago, when I found the mechanics at an USAF base were using it for everything. Yes, you have to shake it constantly as use use it, but plain and simple it works. I use it in the industrial boilers at work, nothing I've tried works as good.

I actually just got me some of that evapo rust stuff and i was wondering what it might have the potential to do with a rusted fastener. I had a file that was pretty dull on two sides and fair on the other two, i was rather surprised to find it taking on a razor edge.
I was looking to try Boggs Tool Company to sharpen some of my files but now i dont know.
In my opinion another problem with the oils is you rather have to wait. I have even tried soaking items in heated oils at around 200F for a week with no result.
I see a lot of people spray things down with the oil but never make an attempt to remove any of the surface rust from the threads. It needs to cleaned as meticulously as you can manage and then do better. Try to tighten it before you round it off, if it moves any it will likely come off by starting to rock it in short increments back and forth.
Oiling the part is not a wasted operation but really any lubricant is going to help a lot.
While its still stuck and still not rounded off, any heat source will be of great help. Most people dont have a gas ax but a propane torch, heat gun, hair dyer, or even a candle might be just enough to do it. Sometimes you just need the extra heat of o/a and sometimes that even wont get it and you have to cut.

i forgot, strikes are nice to remove rusted stuff.
