Big stuck nut

Big stuck nut was created by Claremontcat
Tried Liquid Wrench and tighten first, then added pipe wrench hit by big hammer while pushing on breaker bar, just stripped teeth off (cheap) pipe wrench. Thinking of heating nut w/ MAP gas torch.  Anyone fought a big nut and won?

Check out Jpaydirt on YouTube D9h part 10. Great way to loosen a tight nut.

Watched the Jpaydirt video - spoiler alert, they used backhoe to push on wrench - and I found a 2-1/2" wrench on Ebay that looks strong enough to hit with sledge hammer or push on with backhoe. I thought the 1" drive socket and breaker bar would do the job, but the way it flexes makes me think I could break the tool before the nut comes loose.

Removing nut to build a hitch for a log arch - copying design from photo of Hyster hitch that went with the D2N winch.

There were several different designs and different nuts for those hitches, I can help you with pictures and dimensions if you need it when the time comes. Those nuts are usually pretty snug, but will come off with a big impact wrench or a slugging wrench, just takes some persistence.

Unless the 1" handle is low quality you should not be able to break it. I have had a 6 foot piece of pipe on my tee handle and doesn't even look like breaking. For a nut that size you could also try using two hammers to persuade it a bit. Use one as a dolly and hit the opposite side of the nut. i have had nuts come loose just using that method.

Heat it with a acetylene torch and make it red orange. Hit it with one of those Milwaukee M18 3/4" impact guns. They are very impressive. That may be all you need without any heat.
I doubt you'll make it hot enough with a MAPP gas torch.

heat it with a proper heating tip and oxy-lpg(propane) ( much better for heating) let it cool and try again (mapp torches are for soldering plumbing). if you have a cutting torch get a piece half inch plate and cut out a slogging spanner as its made of steel plate it doesn't matter if you bend it where as big spanners get expensive fast.

a mix of kerosene and diesel works well but it takes time soak it heavily and let it work reapply as it soaks in.
that thread might be a bit burred over file it tapered a bit that might help ive chased burred threads with triangle files and a hacksaw blade.

ive done as phil suggested too it works surprisingly well some thing about actually getting a proper hit on the part, the second hammer sort of acts like a mirror and reflects the force dont ask me the physics ive just had it work. works well on tie-rod ends and ball joints
