Re: Winches through bolted to mast?/unsticking bolts

"You're describing dead shorting a house bank battery. Just because it's rated for 80 amps does not mean it will only deliver 80 amps when shorted."
Good point. In fact, even a group24 car battery can put out 3000 amps into a dead short across the posts. Given a bigger battery or battery bank, the only thing limiting the current will be the cables used.
How about...since this is a winch? Take a rope on it to the nearest unmovable object, and winch it up. If the tree doesn't fall down, the winch will pop off, or the rope will break. (Heads up.) With a good rope and good tree, I've got to think the winch will pop off, unless some clever SOB bedded it in 3M 5200.<G>

Re: Winches through bolted to mast?/unsticking bolts

Give this a try. I used it to take out some broken off screws from an Edson pedestal. I don't know if it was a fluke or not but it did work for me.

Get a bottle of CLR from the hardware store and squirt a bit around the screw or bolt. Wrap a bit of cloth around it and dampen with CLR if the screw is in a horizontal position. I found that after about 3 applications you could see it foaming ever so gently and gradually disappearing down the length of the screw thread. Application of a pair of vice grips got it out first try.

CLR is a commercial product, CLR stands for calcium/lime/rust.

Sounds like Hydrochloric acid (Muriatic acid) especially the foaming on rust or CaCO3 - they sell 1 gal at HomeDepot for about $6 - you'll find it in the pool-cleaning section or the high-pressure was section (good for cleaning concrete) it's dilute enough to put in a squirty-bottle..,
