Anyone know or venture a guess what the shooter was trying to accomplish with this tuning session? Besides the obvious - paper tuning.   |

Lets see? Maybe shooting with eyes closed after concentrating on a spot. No it couldn't be that, Ive seen you shooting before and you seem to struggle with eyes open. Just kidding Dave, but what are you trying to acomplish?

Bare shaft tuning.  Trying to get bare shaft to fly like a fletched arrow. |

I don't know but I would not advise standing on this side of the target |

Kenny, it was Chad doing the shooting.
For those who may not be aware, carbon arrows have a stiff side. Once he had the bow tuned so that fletched and bare shafts enter the target at the same POI and angle at 20yds. He stripped all the vanes off the shafts and proceeded to nock tune each arrow through paper to insure each arrow comes out of the bow the same. You can see some of the shafts had different tears. By rotating the nock you can clean up the paper tear so that they all bullet hole. Granted, the shooter has to have good form and can break a clean shot repeatedly.
Just something the obsessed for accuracy do to get the most out of their equipment.

Last year I got some bolts from south shore archery that were spine match and fletched accordingly. All six fly to the point of aim out to fifty.Until I new about this I was happy with 3 inch group at 50. Now they all fly to a inch at 50 if I do my part.

If there is a spine it should be slightly heavier on that side of shaft. If you would spin test the bare shafts the heavier side of the shaft should stop with the spine facing down or 180 degrees from top. Does this make sense or have I lost my mind?

Heard good things about Jerry's arrows, be a lot simpler than putting the extra time in to do the testing yourself. |

Kenny, some people say you can plug the ends of a shaft and float them in a tub with some soap in it to find the stiff side, others say it isn't a legit means of testing. There are a several methods people use and you will get arguments on pretty much all of them as to their legitimacy as a way of testing.

Then my question would be, are carbon shafts made by wrapping them on a mandrel?

I thought they were extruded, if wrapped on a mandrel they are much more uniform than I would have expected.

I agree with you Edge, if wrapped on a mandrel I wouldn't think they would be uniform.
