Can you incorporate an o ring groove into the nock? That would definitely help with bore sealing and you could lubricate the rings to help with loading.

Don't even need a groove.Instead of concentrating on getting both ends of the nock a perfect size I can concentrate on the arrow tube end and then just slip a 9mm OD o-ring onto the narrow end of the nock before it enters the arrow tube. Even if I print the larger end OD slightly smaller the o-ring will make the seal and slide down the barrel easier than the much harder PETG plastic. No more need to size to the barrel. Just slip on the o-ring, use a drop of adhesive on the small cylinder of the nock before pressing it into the arrow, and that should do the trick and make things much easier!Actually that would also work with the .45 caliber. Same nock. Larger OD o-ring on the narrow cylinder end, larger end wide enough to hold the o-ring in place against the arrow tube without it hitting the sides of the barrel.
Very cool design, I have been looking at the cold steel version for cheep small game heads. My concern is how do you get them out of the arrow/bolt after they break? They will almost certainly break where the wide head meets the thinner "shank" inside the arrow shaft
The silver metal collar the arrow head screws into pulls out from the arrow tube with a pair of pliers, and the busted threaded shaft will be sticking out the other end of it.Something like this should accept pretty much any OD o-ring we could use for the arrows.
O-ring type arrow nock is finished and ready for an o-ring
Very cool, Jared!Do you plan on sharpening the edges before a hunt? If so, how would you actually sharpen it?
I would try printing a 3 blade like Snuffers or Woodsmans
