Those ferrules are made out of whats called micro-balloons. Before being formed into a ferrule they are very small, white, soft, very lite hollow balls. I don't know for sure but the heat from polishing the ferrule may cause the air in these micro ballons to expand. About 10 years or so ago I put a tip on my first Predator and proceeded to polish the ferrule as I normally due. As the shaft was spinning the ferrule started to feel differently. I stopped the lathe and the ferrule hung down like a wet noodle. I grabbed the ferrule and held it straight out and when it cooled it stayed straight but I have never burnished a Predator ferrule in that way again. Now, I buff with jewllers rouge for a very short time and let it rest for a few seconds before I do it again. After doing hundreds of Predator shafts now, I've never again had the problem and I hope I never do.

Thanks,
Makes sense, and explains It alittle better to me. That's probably what it is then, The ferrules weight could back that up also. I did'nt know they would melt down like that, must have been the pits. I'll know to watch out for that from now on.
It does'nt happen everytime to me just every once in a while, when in a rush. maybe twice at the most this year (too much for Me
) I live about 30 minutes from them, and have tipped a few myself over the years, so guess like with the tips, not bad odds, and I should'nt complain. Alot of people like them & use one. I put alot of mooris on them.
Your correct about letting it rest to cool down. that's what I do also, and I'm usually safe like that, I just get in a rush sometimes, wanting to go to sleep, but have to finish a bunch of work up first, and one will reach out get me. Just a slight change where the wood meets the ferrule, the area we work so hard to preserve, so there's a smooth transition between the 2. It's fixable, just time consuming, when I'm just doing a tip job and no shaft work. I don't mind cleaning up shafts for people, but when It comes to the preds I prefer not to, unless they really need it, because they do seem to have a sanding rate issue between the 2 imo, as I believe is what Richard was refering to also. He's right you can get a mess going if not carefull.
Just a couple of things I noticed Like you guys, and most definatly not limited to just those shafts. I get other standard shafts that act the same way sometimes. the ferrule material even seems simular. You learn to live with it, try not to make more work for yourself, and do what It takes to get It right if you do. Goes with the territory I guess.
