You used to be able to rent one from Advance Auto or similar store. Harbor Freight has a cheap one. I have seen some guys yank on it hard enough to pull it off after the bolts are removed but thats usually not the case.
I put my knees under it and push off my toes, with nut even with shaft and put a hammer on nut and smack first hammer with second, off it comes.
worth the money and it can be used to pull other things. https://www.google.com/?gws_rd=ssl#q=steering+wheel+puller&tbm=shop&spd=6258643218234289541
Back the nut off but don't remove it, it may prevent you from 'taking it on the chin' when wheel comes loose.
I tried for weeks to get the wheel off in my '56; that damn hollow steering shaft is a stupid sonofabitch of a design (sorry Henry, but it's true)... ended up working around the wheel to get the turn signal switch rewired, which was my original purpose in removing the wheel. Same damn hollow shaft in my '51, but I DID get that one loose.
