Horn Nock Cross Section

[Del the cat]

I know it's not a bow, but I thought this pic might be of interest. I had this old ELB tip from a smashed bow lying around so I sliced it through the bandsaw to make a little demonstration/show piece. It shows a slight glue filled gap near the tip, but otherwise it's a pretty good fit, also shows how a curved taper fits in and how little horn is left.
Also shows how I cant it a little towards the back of the bow and the core of the horn runs pretty centrally.... great nock... shame the bow blew!

Half core wood, half sapwood; is that yew Del? (no pun intended)

  Nice Del, is that about 1" of bow pushed into the nock?

[Del the cat]

Yes it's me, I mean Yew.
Just over 1" into the horn 1 1/16"

I use a wood bit ground down to a curved point. As shown here.

Very nice Dell but you do know you could have removed that nock from the bow right?

I figured that being epoxied on it would be too much trouble, and if I got it hot enough it would probably deform or collapse. I'm pretty quick and slick at makin' them now anyway. I even enjoy it! When I did my first ones it was a real pain and I hated it!
If you have a way of popping them off I'd be interest to know tho'

All you need is heat Dell and they are serviceable after, you just have to be careful how you apply the heat.  If you get them too hot though they start to turn color and that's not so good.  I've always just used a heat-gun but I wonder if boiling them might not work.

Or you could just drill out the wood with the same bit....
