So what is that???? Nock-tuning? Did good old Dutchie finally loose his mind?
No no no....
Today I made a major improvement to my set-up. Since a long time I was not quite satisfied how my arrows were in the pack after the shot. Okay, the flew great and I was hitting were I was looking at, but they were never straight in the pack. Always feathers left, point right. Not much, max 1 inch when papertuning.
This would indicate a too weak spine, so I went up 5 lbs, 10, 15, and still the arrow was not straight in the pack.
Sometimes this can be frustrating, even though you are shooting good.
Then I remembered something about the nock-fit on the serving of the string. I am the kind of guy who always said: "As long as they don't fall off, they are fine!" and never payed attention to it. However at a closer examination today I found that my nocks are very tight on the serving of the string. I sandpapered the groove, with a piece of sandpaper, two times folded. It was a 240 grid, just because it was laying there around. I sandpapered the nockgroove till the arrow, hanging down on the string, just didn't fell of.
I shot it. I couldn't believe the difference! The arrow was now very straight in the pack AND flying noticeable faster. Much faster. Judging with the eye I would say 10 fps at least.
I treated all my nocks this way. Taking care that the fit was in such a way that the arrows just didn't drop of, when hanging down on the serving. Just a very light hit of the finger would make them drop.
Tryed them all. My set-up was shooting much faster, more accurate, quiter and more forgiven.
I can imagine that when you have a very tight fit, this may cause the loud TWENG when the arrow leaves the string (read: nock plops out of the serving) some people are reporting.
So I really would recommend you to tune your nocks!
Any comments or reactions after a field test are very welcome!
