Here's a neat little product I saw a few years ago.
Shaft pullers are really needed for graphite shafts. It's too easy to overheat the hosel and cause the graphite shaft to splinter and ruin the tip section.
With steel shafts you don't have to worry about the shaft splintering, but if you're looking for more of a professional job and not singeing the hosel, a shaft puller works.
Most shaft pullers require some manual pulling of the shaft. But, the Holtzman shaft puller is hooked up to an air compressor and as they demonstrate in the video below, with a minimal amount of heat the shaft can be easily removed like a professional.
The Holtzman shaft puller is available for $119. You can find it at this link:
