It can’t be stressed enough that if you’re going to try to press it or hit it, you MUST use a nut on the shaft. It is very soft and the threads and even the cotter pin hole will fold up like butter.. I guess that if it were me (and it HAS been) I would start by getting an expendable nut and put it on the shaft, down to within an eighth inch of the prop. Then I would heat the prop quite hot and hold it in my hand with welder’s gloves and try hitting the prop shaft and nut and see if you can get the prop moving that one eighth inch, to begin with. Don’t try to support the prop in a vise, as the blades will be damaged quickly. Make sure you hit the nut very, very squarely or the end of the shaft will bend sideways. Then you’ll be drilling it out, like Tubs says.
Long live American manufacturing!
