Hi,
Just bought 2 packs of pre-made horn nocks off ebay for £4 a pack. They just need glueing on/final fitting/polishing.
I think that they are a fantastic price - the quality looks spot on. Here is the archery shop:
eBay UK Shop - J J Traditional Archery: Nocks, Arrows, Arrow Shafts
they also have a website
J &J Traditional Archery Supplies
I'm still getting into bow making; and buying these off the shelf allows me to concentrate fully on the bow.
Cheers, Dave
