I'm faced with this every so often in my work, and my go-to methods are:
1) 6' lever arm, which you tried,
2) cut off wheel in angle grinder, (already suggested) which is ultra
fast and always works, as long as you have room to get the tool in
place. It's amazing how much damage you can do with one of these little
tools...

Hi...
I am changing out the T-Bar base on my TX472.
[You may recall, my old TX472 was bent at the base of the tower during H.Sandy.
The replacement tower has arrived]
I tried using my wrench to undo the 3 nuts (on 3 anchor bolts), but I wasn't
able to budge them.
Then I slid a six foot long, 2" OD mast over the end of the wrench and for two
of them (barely rusted), they easily turned.
But one of the anchor bolts (1.125" diameter) the associated nut is heavily
rusted, as is the bolt. Over the weekend, I applied Naval Rust Dissolver Gel which
sort of worked. At least enough to demonstrate that the threads are still in tact.
I also showered it with Liquid Wrench (several times).
But even with the 6 foot long lever arm and "cautious" pressure, I was not able
to budge the nut.
I know that when nuts have "frozen" before on much smaller bolts (5/16" or 3/8"), I have been able
to (unfortunately) break the bolt instead of loosing the nut while applying "lots" of rotational torque on
the nut. While a 1.125" diameter bolt seems pretty hefty, I am concerned about doing the same (yeah, sounds
ridiculous)..and then I"ll really be out of luck.
Any suggestions on how to proceed?
Thanks,
