OK, so here's what went down...
Basically the cue maker and I never really got the chance to discuss what happened and what we were gonna do about it in a one on one manner, but I finally caught him today. First he said that he had heard I was on this site, and had identified him to everyone, which is completely untrue, I purposely never mentioned a name. (except too one person in a pm, and that person asked who it was and knows this cue maker so I was honest) Anyways, before I could explain any of the truth to him he asked to see the cue, and asked if he could have a moment to see if he could fix it.
I agreed to let him, figuring that either way the insert would need replacing whether he wasn't able to fix it, or even if he only managed to screw it up more. So, he took it into his shop and returned within about ten minutes or so with the cue screwed together, he told me that there had been some burrs that had been preventing the cue from screwing together. Where the burrs came from I don't know, last I knew metal doesn't just grow burrs.
I looked at the work and it was well done, I don't think he re-tapped it, just cleaned the threads up. So, the cue is good as new. I explained to him what all I had written on this site, and that my reason for posting here was for information, and advice, and not to bash his name at all. I'm really glad he was able to fix it, I never asked what caused the damage in the first place, I'm just happy to have my cue back.
Honestly, I will most likely have the guy do more of my work in the future, but probably not on my Predator, simply because he told me he doesnt have the Unilock lathe pin, and I don't want to risk a repeat incident with this cue. As far as the other cue goes, it was a misunderstanding as far as what he thought I wanted him to do with it. This I can believe because it was one of those "Here, whenever you get the time can you do this for me?" deals. Where I basically just handed it to him knowing he wouldn't be able to get to it for a while. Besides it is a cheap cue that I keep as a bar player, and the new ferrule actually plays a lot nicer than the old one.
So, to sum up. He repaired the cue for me, no problem, and explained the misunderstanding with the other cue, also no problem. He also apologized for not being able to get to it sooner, and I explained what was really said on this site. All's well, and I hope that he feels the same. Thanks everyone for your help, if anything, this has been a very educating experience for me.
