Hi,
ive sometimes had problems with fletching falling of the arrow for some reasons and as i want my gear to be as reliable as possible i started winding them down.
I made a little pictorial about it as i thought perhaps someone might be interested. I dont say its the best way to do it, but it works very good and fast.
Anyway, hers how i do it(Big apologies for the blurry pics, i used a selftimer and sometimes the focus was off):
1. Materials needed: Dental Floss, Superglue
2. put a small dab of superglue on the shaft just underneath a feather:
3. Take a piece of dental floss (ap. 3-4 feet) and glue it on:
4. start winding till the first part of the quill is held down.
5. Take another small piece of dental floss, form a loop and place along the shaft over the winding and start winding back towards the tip of the arrow. Its easier if you stick the end of the loop-floss into a feather. (the "Loop-Floss" is made black in the pic):
