heat them first. A little propane torch will heat them up enough without melting. When you tap them with the hammer & they fall to the floor ignore the instinct to pick them up immediately, particularly if you are bare-handed.

Remove the crank bolt(s), and ride the bike.

The crank(s) will quickly come loose. Stop, and then pull the crank off with your hand.

i dont have a torch. and the crank is the last piece i need to take off, so reassembling everything else would be a hassle. im about to go for the 2 by 4 or crowbar.

Are you trying to take off the crank? I am confused with your description above?

A crowbar would mean applying undue force on your frame. I would avoid that if possible.

If you have access to a gear or bearing race puller, that might work.

However, I would first try some liquid penetration oil then ride the bike around the block with the crank bolt left out as suggested earlier. Lightly tap the crank on the sides then take it out for a ride. Be careful because the crank arm may let loose unexpectedly. So be careful when applying pedal pressure. That should free up the crank and you would be able to take it off by hand.
