So, I have an old scavenged shogun roadie, and the driveline took a huge dump, so it's been sitting doing nothing. (think derailer into the spokes, chain turned to a pretzel, drop-outs tweaked to hell, etc)
The other night, I snagged an OLD OLD OLD schwinn road bike out of a dumpster, and the driveline looks great (unlike the rest of the bike), so I have been trying to move the parts over.

One of the last things I have to do is remove the cranks, but this happened

this thing is jus hella stuck, and isn't going anywhere anytime soon.

Anyone got any ideas? I want this crank with the sprocket cage, the sprocket on my shogun is bent, so I'd like to keep it in one piece.

Had the same think happen a couple weeks ago on a Truvativ Howitzer BB. This was our solution, only works on the drive side though.

I just gave up.
That was with a blowtorch, and a hammer assisting, too, that crank isn't going ANYWHERE.

I'm just "stuck" with a single front chainring, now. It'll be fine.
