There are three alternatives I know of:

1st: If the threads are not totally stripped, have the treads chased by a competent shop (or buy the tool).

2nd: Use an automotive bearing puller.

3rd: Use the bearing puller with a little heat. Do not heat the cranks over 400 degrees F for any length of time.
