Bare shaft nock high

[gordydog]

My 54" hybrid bare shafts with a porpoise in flight, nock high in target. Right/left is perfect. Bow is held vertical. Arrow nocks loose. Two string nocks to prevent arrow slide on string . Played with nock height 3/8-6/8. Even pushed out strike plate to experiment which wasn't called for. Is it a short bow issue? Tried several different arrows and point weights. Fletched arrows have a slight porpoise before correcting too.
 My 66" recurve has "perfect" bare shaft flight.

Do you have other bows to compare with?  If it happens on other bows, it is probably a form issue.  If it only happens on this bow, it is more likely to be an equipment issue.

[gordydog]

McDave, only noticed with this bow. Maybe form flawes show with 54" bow?  What possible equipment issues would you suggest looking at?

If you shoot split, the top finger often puts downward pressure on the arrow causing it to flex slightly. As the arrow rebounds from this flex it'll go nock high. Shorter bows cause more pressure from the tighter string angle.  At least in my experience.

Short bow, what's your draw.
 I'd agree on finger pinch being a likely culprit.
 If you shoot split.
 For me at 28" draw I find problems with split finger show up at around 58" bows and shorter.

Since you mention two nocks, I will hazard a guess that you are gripping the string 3 under.  Short bows can exaggerate the tiller problems from shooting a bow 3 under that was tillered for split fingers.  This can result in the limbs being out of time with each other such that they don't return to brace height at the same time, which might result in porpoising.  You might try holding the string 2 under, if the bow is light enough that you can do that without discomfort.  This might balance the pull between the limbs better, or at least make it closer to a split finger pull.  Some people pull with the index and middle fingers under, while others pull with the middle and ring fingers under, and just keep the index finger off the string by pointing with it, I think.

Another possibility is that you could correct the tiller by building up the rest higher, rather than raising the nock point.  That worked on one of my bows one time where I couldn't get rid of nock high any other way.

Try more heel of the hand pressure.

Adjust your nock up or down with the bare shaft

Not that I’m any expert or have been doing this that long , I solved my always nock high bareshaft with a bear weather test. No matter where I put the nock point it was nock high. The rest shot bareshafts like a laser.

Had a Pearson Signature T/D that constantly showed nock high.
After much gnashing of tusks, figured out that the nocking point was actually too low and the shaft was bouncing up off of the rest ............. showing nock high.
