If it's a common Bullseye with a flare tip shaft, the head goes into the shaft just like the one you have pictured. These are normally very easy although the head can develop a pretty tight fit with oxidation over time. Depending on the heat gun model, that may not be a high enough temperature. I'm surprised the propane hasn't done the job. With a hot flame, heating the shaft all around by the head for 20-30 seconds should be enough. You don't have enough heat to damage the head and don't worry about the shaft discoloring because it is damaged already. If the shaft is held securely, you should be able to twist the head right out.

thanks ken.

it may be oxidation or i just need a set of younger arms for twisting.   i'll try (with help) again.   i may try squirting a little p.b.blaster down the shaft to loosen up the possible oxidation?

as soon as i find the solution, finishing up my bullseye putter collection should be a piece of cake....i'm only missing one style (see attached).   i've found a couple but either the putter was in terrible shape or the owner was asking way too much.

Sometimes it just takes a while. As in, put some heat on it around the area that the flare tip ends, up about 2"+. That way, the whole thing will be heated up and the epoxy will loosen up eventually. I wouldn't mess with PB. You don't need it. Some of the older clubs epoxy just takes a while longer to heat/loosen up. Just keep twisting. If it doesn't move, more heat/time is needed. Twist again. Eventually it'll twist easily and come right off.

Success!  

Thanks for all the tips.  The method that worked for me was to heat up about an inch and a half of the shaft quickly (the brass blade acts as a heat sink and will take more time to get hot).....about twenty seconds or so.  The difference in expansion is enough that a quick twist will separate the shaft from the brass hosel.  Too much heat and the brass hosel  will expand into a tight fit again.

Except for the one Bullseye mallet, my collection is complete now; all of the models with 35" shafts, Bullseye logo caps and Bullseye leather of simulated leather grips.

My three non-Bullseye putters are and Otey Chrisman (my first putter), a Ray Cook Mallet (the putter I use while on the army golf team) and a png Pal (a gift from my family).

I use all of my putters.   Right now (probably until the end of the season), my Bullseye of choice is the wide flange with a T-slot.

Thanks again for all the help.  Thanks Acushnet and Titleist for the Bullseye putters.

Good to hear that Joseph. Few things are more satisfying than finishing a hands-on project.  The first new putter I ever bought is an Old Standard with two sightlines. I still have it both for sentimental value and practice. I absolutely believe it is the reason I became a decent putter. You have to be disciplined and hit the ball squarely to control distance and direction. Plus, Bulls-Eyes are just beautiful to look at!

Glad to hear that you finally got it.
