I recently picked up a rough shape 91 stumpjumper that i want to turn into a commuter.

The sealed cartridge BB is stuck.....and i mean stuck. I have been soaking it for a few days now in PB. I have a m8x1 sae bolt running through my bb tool into the spindle to keep things nice and lined up and tight as those spines dont seem to like to stay seated. I have been on it with a 12 inch adjustable wrench and no dice. I have even take a 2 foot 1/2 inch drive breaker bar and 1 inch socket to it and used a cheater bar but still no dice moving things on either side.

My next thing is going to be trying to soak it longer and use a impact gun on it. This may sound extreme.....and it is but this thing is STUCK. IT appears to be steel cups and a steel frame. I am not sure how it got so tight.

Anyone know of any place that rents electric impact guns?

I dont want to put a torch to the frame and i am 99.9% sure cola and lemon juice and all that wont work at this point. I have time on my side and am going to let it soak for a few weeks while i either source an impact gun or come up with another way.
