Has anyone ever made their own nocks for arrows from bone, horn or antler? I've just bought a big pair of solid buffalo horns to try and make arrow nocks from. I'm probably going to try for a mortise & tenon joint. I'll need to experiment to see which way woks best. The horns are 65cm tip to tip so I can do a fair amount of experimenting! Hopefully with the horn and the period arrow heads, I'll soon have some groovy (reasonably) historically accurate arrows to show off in another couple of months. Oh yeah, and bone, horn, antler and shell can really screw up your lungs when sanded. The tiny particles just shred your lungs, so be sure to use a proper breathing mask to avoid major lung damage.
