I typically run 2 to 5 minutes depending on the material and style of
head. I put the club in a GS shaft extractor with the head tight against
the stop, back out the jack screw on the puller 4-turns to fully compress
the spring, and apply the heat gun on high to the hosel near the middle of
the 30-mm shaft bore for long hosel irons and nearer the club head for
short hosel irons and woods (to try and compensate for the heat transfer
characteristics of different head designs). I only apply head from one
side. The heat gun heats slowly enough that the hot air flow around the
hosel and heat transfer within the hosel equilibrates the temperature in
the hosel well enough to prevent hot spots. I keep heating until the head
breaks loose and starts sliding off. Then I remove the heat and finish
pulling the head with the jack screw on the shaft extractor. It's not
fast, but I have yet to discolor a hosel or damage a shaft tip.

I have a heavy duty heat gun and I've yet to be successful (or patient
enough) in pulling a head with this method.
Just wondering what the average time is for heating the hosel before
trying to pull the head.
