how to remove old steel shaft from irons
If I may add, it’s always good to use safety goggles and have a fire extinguisher nearby. Be sure your grip solvent is nowhere near you when you heat the hosel. When heating the hosel, you may have a small flame from the melted epoxy (or if any of the ferrule is still there). You can easily just blow it out. A heat gun is safer and slower, but is definitely better whenever you remove a graphite shaft. As Popeye said, be sure to do a thorough job of cleaning out the hosel while it is warm.

If you are going to be working with clubs I would say to get a decent shaft puller, sooner or later you will do graphite and need one. A dedicated shaft puller will work perfectly on a steel shaft but to be honest, a shaft clamp and a heat source is all you need. Clamp the club in the vice and slowly heat the hosel evenly. Sometimes you can see the epoxy flash, but after a brief while take an oven mitt and try to rotate the head off of the shaft. They come right off. While its still warm, clean out the hosel. If you try this with a graphite shaft it will simply splinter and break. That’s were you have to own a puller.
