Hi All,

Longtime lurker first time poster. I've had a really amazing time sifting thru all the golden nuggets available on this site. With all the info, I probably shaved off several years of "trial and error" to get where I am today.

That said, I am posting to those that bare shaft tune while string walking cuz I can't quite get the results I am looking for.

Here's my case.

I shoot a 25yd fixed crawl about 1.5" from the knock set. Index finger corner of the mouth. Repeatable, with fletched arrows i get a 4-5" grouping. When I shoot the bare shafts, they also group. Except they are a foot low and a foot right of the fletched.

fwiw, nock is also dead straight on the bareshafts.

Whats confusing me is if I GAP shoot the bare shafts just under the nock set, I get the arrows to group with the fletched that I shot with the fixed crawl.

Is this a tiller issue (I'm 0 to -1/8)?

Should I bare shaft tune using gap method, even though I will invariably be shooting stringwalk?

When you bare shaft tune do you do so with your hand directly under the nock set or do you do it with a crawl?

Thanks

Right handed?

Im a southpaw

These are 600 spine 85 grain points. Arrows cut to 28.5" with a 28" draw. Shot from 36# bow.

Didn't include this because of the fact that the nock is dead even (which means the spine vs. length vs. tip weight is seemingly inline)

They are too stiff and possibly your nock point is a little low.

Thanks, I'll try shoot 100grain tips today and let you know.

This still doesn't address why the bare shaft arrows shot using gap method grouped better than using a fixed crawl stringwalk. I think this is because of a tiller issue but wanted to hear other opinions.

Not tiller related. Stringwalking changes both dynamic spine and nock height requirement. You are using two nock locators correct?

When i shoot a fixed crawl 25yd the crawl is only 7/8” under the nok as i recall ( i shoot long heavy arrows) my nok setting is about 1/8” higher with that vs shooting with my fingers touching the arrow.

I have to drop my Bh a little too when shooting fixed crawl for it to tune.

Arrows too stiff, try a 125 grain point. You will need to move your nock point once you get the spine right.

IMO... it could be tiller related. I shoot a 1/8" negative tiller with my 20 yard fixed crawl on my hunting bow.

What you've described is a too high nocking point and a too stiff arrow. First thing I correct is nock set height. Once I get the bare shafts and arrows hitting the same plane, then I work on spine.

Sounds to me like you're shooting well enough to get it worked out. Good luck.

Tune to how you shoot.

Make the bare and fletched group together with the fixed crawl you plan to use.
