Some of you folks are pretty creative.
When I got started back to Trad, buddy got me into using ash for arrows. I bought one of Dean Torges' v-block set ups to taper arrows.
The danged ash had so much "runout" in the grain we used to get, that if I forgot to mark the grain orientation before I ground the nock taper, I played He2Xhockey sticks to find which way to orient my nock perpendicular to the grain.
I got so ticked off one time I hollared at my preacher bud and said, "What the devil? You need a Ph.D. to figure out which way to orient the nock or what?"
Doc Nock kinda eminated from that. I'm not a real doc, I just play one on the internet (Another euphemism from KillDeer-the-sharp-whit)
