Ok to fly off on another of my tangents.
Get yourself one of these super cheapies.
There are "real" versions, but I bought a cheapo chinese Amazon and so far it has worked great. This gizmo falls into the "where have you been all my life" area of tools.
If you work on shit you will come across a stuck bolt, you get to each one of these steps and I personally have done all of them.
Issue with the "blue wrench" is well fire, and that can be a bit of an issue in some places.
When I got the induction heater I was like this thing can't work, so I heated up just a loose bolt, WOW, smokin in no time. Ok lets see if this works for real. Rusted wheel nut on an 8n that likely has not been off in 80 years, sure enough right off.
One word of warning however, it is just like the blue wrench, so don't use it to take off rusted spring shackle bolts, that rubber shit will smoke like a mother fucker.....for fucking days if you are stupid like me.
You go from, Well duh you idiot, it gets hot naturally it will melt the rubber bushing, but it is not that bad.

I think I need to move to another state to get away from this smoke.

You know I can't do this, I will come back next weekend with the fuckin grinder and cut the stupid nut off like I should have done in the first place.
