My 314-2 shaft split. No water, no sanding, just the glue lines failed, presumbly. Ive owned 5 or 6 predator shafts and only one has never had some problem or other, a first gen z. I loaned it to a mate, and he jammed it in a door frame within a week. :angry:
That's very odd and I would have loved to see the shaft, the first thing I would do is smell the shafts when they came in after looking at them for obvious sanding or swelling of the wood. Smelling the shaft tells you what they use for cleaning, like Ajax, which is usually mixed with water and explains the shaft separating. If you saw how they were put together and glued it's hard to imagine there being an area where the glue didn't hold, especially with a glue where the bond is stronger than the wood itself.
