I was thinking about these posts about Platinum when I was stump shooting the other day, and my arrow happened to hit a branch at an angle, which totally destroyed the arrow:
You will note that even though the shaft fractured and broke off, and the feather was skinned off the shaft, the quill remains tightly bonded to whatever shaft is left.
This was fletched in my usual way, described above. I am really puzzled why I and a few others use this product with no problems, while others can't seem to get it to stick. I have had similar good results with Gold Tip trads and Easton aluminum shafts.
The only additions I would have to my previous post about how I fletch are that I put a drop of glue on the each end of the feather, as do most people. I don't do any particular shaft preparation; just use them as they come out of the box. I do press the fletch down as hard as I can against the shaft without dislodging it for about 5-10 seconds. Then I let it sit for about 15 minutes before rotating to the next position.
I would like to solve this mystery, but don't know if we'll be able to figure out why mine stick and other's don't.
