Questions about self nocking arrows

[Kirsh01]

I am looking to make a set of self nock arrows.  My question is, is there a poundage of bow where self nock arrows become impractical?  Also, is there a tool recommended for this process?  I have seen the "Nifty Nocker", and was wondering if anyone had any experience with it.

I have used a hacksaw to start the cut, then a tile blade and a chainsaw file to finish the nock. As long as you wrap the shaft below the nock you should be OK.  

One thing to to watch, though, is that the nock is big enough for the strinng. The only self nocks I have split were too tight on the string.

Good luck!

P.s. you can also use a spline, but it's more trouble.

The old 150# English War Bows used self nocked arrows.
  I make a single bandsaw cut then fit it to the string with a thin bladed knife, small file and sandpaper folded over and over to increase the nock opening. A wrap is very important with self nocks unless you reinforce it with a spline like Scattershot posted.
 For wrapping I use either sinew or silk thread set in super glue. I chew the sinew so no glue is needed.

A five dollar tile cutting blade in a hacksaw frame does a perfect job of making self nocks in a single pass.  Make sure you get them centered!
