String nock 1 1/8" above level..Is this a problem???

[Zradix]

I received a new bow a while back.
In order to get my arrow flying decent I had to put the string nock 1 1/8" high.
The arrow looks like it's going to shoot right into the ground when sitting on the shelf.

I've never seen a bow that needed to be set up this way.

Does having to do this mean the tiller is way out?

Thank you

What are the bows stats and what kind of rest and the arrow stats are needed as well.

[Zradix]

It is a Siegework Creations GenIII. 46# at my 28" draw
The bow is 57" tip to tip when strung. It doesn't have a listed AMO length. It seems to want a 8 1/2" brace.
The arrows are 60-65 spine ash with 190 points.
Or 50-55 spine spruce with 125grn points.

I'm also shooting split finger.

I'm using a bear hair rest with some thin peel and stick felt on the window.


I don't have the spine perfectly tuned in.
Just thought it was weird to need the arrow nock soooo high to keep the arrow from porpoising.

Thank you

Oh..
A lower nock point just makes it worse.
It doesn't seem so far off that it sort of "came back in" if you know what I mean.

With a nocking point 1 1/8" high, something is definitely wrong. Can't help though. I shoot aluminum arrows.

Good luck.......no, 1 1/8" high isn't normal.  I traded the one I had off just so I wasn't reminded of all the hassles I had with him.

do you know how to check for tiller on the limbs ?  I would look at the bows tiller and see if it is reasonable.

No I don't....yet

Lots of good info here on that though.
Just didn't want to have to test and work on a new bow.

As it so happens, I have a replacement bow being made. The guy wouldn't refund my money. The bow has other problems as well. I was to have had it 2 weeks ago   :rolleyes:

Just worried what new found problems might come up with the new one.

I was told by the bowyer that 1 1/8 isn't all that far off and might be the string.( which he supplied ).

Just seemed wrong.

Thanks.

been playing this trad game for better than 50 years & never ever heard of that.

I have a Bob Lee with a 1/2" high nocking point and I thought that was pretty high. You definitely have a problem-- those arrows sound a bit on the stiff side to me as well.....  

[Cory Mattson]

did you try 5/8ths above the shelf ?

I shoot wood arrows, most bows nock at 5/8 for my tuning needs.
Nock height generally has to do with shaft diameter and shooting style................split finger, 3 under and not affected by tiller.
What do you mean by 'porpoising'?

[Blackhawk]

I shoot split finger and generally set up my bows at 5/8" to 7/8" or more.  

I have a couple Widows at 7/8", so your 1 1/8" is only 1/4" from that.  If you are getting great flight, I would not fret over it too much.  Yeah, it may be a tiller situation and if the bowyer is "fixing" it, then fine.

Otherwise, it just seems we are making something simple soooo complex.

Yes no good till way higher.
In fact I started at 0"

The fletching moving up and down considerably when the arrow is flying towards the target.

Thanks

[lpcjon2]

I would start from scratch.7-8" brace and 125 up front and center for the nock and adjust from that point.could the feather rest be hitting the fletching and making the arrow kick up high? maybe try a different rest use the soft velcro instead of the feather rest.

I shoot a high nock 3/4 to 1 inch but I shoot 3 under  so thats normal for me . Im interested in hearing opinons on why some people need higher nock points myself .

[T Folts]

I would think it has something to do with tiller. I would think a experienced bowyer may have the answer, ssomeone who has run across this during developement stages. Any bowyers out there have any experience with this?

[s_mcflurry]

Do you get better arrow flight if you shoot this bow 3 under?

[elkken]

I am one of those guys that a high knock point works best for me, I have a few bows I'm sure over an inch. Most are 7/8 or just above.

I shoot split finger .... like Blackhawk says if they shoot OK at 1 1/8 just go shoot.

Also you can get arrow bounce having your knock too high.
