I tack mine with a small dab of hot melt on the edge. I always use the same set of nocks for this. Then after everything is done, I peal off the hot melt and glue my nocks on. I started doing this because with a left wing clamp and left wing feathers on a right hand bow, the standard setting will put the one feather straight down, the same the other way for my right wing fletcher. For left wings I rotate the nock counter clockwise 1/8 turn from the grain, tack on the nock, fletch and then when I glue on the permanent nock I rotate the arrow counter clockwise 1/8 to correct the arrow to the grain. The opposite way with my right wing fletcher. This first turn is not needed with metal or carbon of course, but the second turn is good if you do not want that bottom henn sticking straight down when you three fletch. I do not do any rotating with four fletch. The other one is to put the first feather on and simply start with the index of the nock pointing down. This will turn the cock feather into the bow with the nock index still out from the bow. I have a set of right wing arrows for my left hand bow this way. If the cock feather is out that hen feather is straight down and bumps a bit off the bow, with the cock feather in, I get no straight down feather and am getting perfect arrow flight without needing raise my string nock to compensate for the straight down hen feather. Man, I think I made that sound more complicated than it is.
