In the world of persimmon, sometimes you will make mistakes, learn things the hard way, and so one. Sometimes in an effort to avoid destroying something, you damage it irreparably. And indeed I fear I have done that with a Hogan Speed Slot driver I wanted to remove a shaft from.
The shaft was graphite and played at somewhere between senior and regular. No big deal, just take it out. But being graphite, that is easier said than done. Someone had been kind enough to remove the backscrew for me. I tried the legendary method of a bagging the head and dipping it in boiling water, which didn't do anything. Next step; I had heard the breakdown temp for these epoxies was somewhere in the 250 degree range. After modifying the shaft to fit into the oven (cutting most of it off) I set to 250 and waited. The insert softened a little but the shaft would not budge. I cranked it to 300, and waited a good 30 minutes, still no shaft. 375-400 was as high as I dared to go, and for good reason, as I watched things start to discolor at that temperature. Dejected I pulled the club out and yanked on the shaft... which served only to exacerbate the cracks in the neck. I decided, perhaps belatedly, that this was indeed a fool's errand, and at that point I stopped.
I wouldn't dare post this in wrx because there are some there who would flame me alive for destroying the club. Rightfully so, so I don't really want to get into a fight about that; my intentions were good if a bit misguided. At this point I will go ahead and bore out the shaft and clean up the neck and reassemble. I have no idea if the heat has harmed the wood in any way, but if it explodes on the first swing so be it. I'll just put it back together and hang it on a wall.
