Yep, I have several dozen arrows that have either reinforced self nocks or sinew wrapped self nocks. They are a little extra work, but I enjoy it. I'm like PatB in that I prefer a looser fit...kinda like a mercury speed nock (which I also use at times). I use the jig sold by Raptor Archery (a sponsor here) or you can use a hacksaw or bandsaw...whichever is at you disposal. I use them on douglas fir, mahogany, red balau, and bamboo shafts. Oh, and I have never had on split or break.
