Hi Joe, all, I still think the taper of the shaft doesn't match the taper of the head. A new Schaff tuning hammer will go through this process. Drive you crazy. The shaft actually grinds off into the head, as it does it loosens. At some point it is almost not removable. Until you get enough threads (about 5-7 turns worth) ground off the shaft, it will drive you absolutely nuts. I sent one back to Schaff and Mr. Johnson thinks it was cross threaded, but it was not. I miss APSCO and Tuners Supply. The taper they used was not as steep. Never had this problem with them.
