My drawn arrow bows in middle

[owlbait]

My buddy said my arrows are bowing in the middle by as much as 3/8" when I draw them back. Various brands, same results. Apparently, I am also getting some porpoising, not much. I can't see it, he can. What do I need to do to fix this?

Keep your drawing arm elbow down.

I'll try that Scott. Thanks.

Owl, place your index finger about 1/8"  above  the arrow nock when getting ready to draw. The finger will "roll" downwards into position and not bow the shaft. And yes, what SL says....

[Don Stokes]

It means you're gripping the arrow nock too tightly between your fingers. I'll bet you also get some serious finger callouses and soreness. Make sure your nocks are snug (not too tight!) on the string so you don't worry about losing control of the arrow, and spread your fingers some. Use a deep grip, to the first knuckle crease, to reduce tension in your hand. That torque you put in the arrow makes it really hard to tune properly. Some tabs have a spacer to help with this problem.

Take a deeper hook on the string and remember to relax the back of your hand.

Thanks to all. I have sissy hands so I don't have much for calluses but I do have a sore spot with the index finger, (side to nock). That could be where I'm torquing? I see how it goes.

Yep, down pressure on the arrow nock is causing the arrow flex.

I agree with Rod.  Ken Beck explains this very well in the arrow tuning section of Masters of the Barebow Vol 2.

Thanks guys. Guess Rod knows at least one thing I need to work on! What did Ken say to do to fix that Darryl, or do I need to buy the video to find out?
