Ken. the posts below usually works. I also found out if you heat the bolt or fitting red hot with a torch then add bees wax to it as its cooling helps. The trick is that the bees wax is sucked into the threads as the bolt is cooling. Has never failed me yet. Dont use candle wax it must be plain old bees wax.

With that much sticking out heres an idea that has worked for me in the past. Slip a nut on the stud that is just a size bigger. Weld it on and then let it cool for about 15-30 minutes and then try a wrench on the nut. The welding heats it up and the cooling brake it loose. I have also to spped up the cooling sprayed PB on it when it was hot. When hot the PB wil go in to places fast that it would go in to when cold

Heat and time are your friends here--heat it red-hot (a propane torch probably isn't enough--you'll want oxy-acetylene if possible), quench with PB Blaster, then lather, rinse, repeat. Another good idea is welding a nut on top and using an impact wrench. Take a flat washer and cut a notch in it, put this under the nut, then weld the nut on top. Pull out the washer, and you'll have a bit of a space between the nut and the head. Put an impact on the nut and work it back and forth. You do not need (and don't want!) full power on the impact--all you're trying to do is jar it a bit to get it to loosen. Once it comes loose, work it back and forth gently with the impact, and it should come out.

Spray it with pd.. grind the nub to a flat.. so you still have the 1" sticking out.. but a flat spot on it. Every time you walk by it.. whack it with a balpeen hammer... no home run hits.. just a whack.. then hit it with more pb oil.

You can use double nuts, or thread a nut on and weld it.. put the nut low, and then you can put a wrench on it.. the heat from the weld helps break them loose... There is also a stud extractor tool that 'may' work.

I've also heated them red, and then quenched them with pb oil.. or candle wax.. it penetrates and lubes.. pb oil quench seems to work the best... alternate between heat, oil, whack with hammer.. oil.. etc..

Worst case scenereo is drilling the center open and using the largest possible easy out to turn it out... use a left hand drill bit.. sometimes you get lucky and will unscrew the stud.. I fthe easy out don't work.. drill it out till you just start to hit threads.. then easy out it again.. or pick metal out with a dental pick.. no fun.. but I've done that... just drill straight and centered.. use a center punch to get you started. Good luck ont he other ideas -first-
