Help with arrow tuning

[Emmons]

Looking for some opinions please.
I have been trying to tuning my Morrison.  I have the newer cheyenne limbs that are marked 60 @ 26", but scale 66 at my 27" draw lenght.  First I tried Beman MFX Classics cut at 27 1/2" with 250 gr. points, these always showed nock high.  Then I tried some 27" 2020 with 175 points these also always showed nock high.  I called Bob and he told me to try some stiffer arrow, because a really weak spine will show nock high some times.  I got some 2219's from Mike Walker and now I am tuning them.  But from the spine charts these arrow should shoot stiff.  I am at 28 1/2" now with 175 point and I am still showing a little weak, but no longer see a nock high.  Do you think something is wrong or this bow just needs a stiff arrow?

Thanks James

Hi James

     My best advice is to go above this thread click in the TRAD GANG SPONCER LIST. Click on A&H Archerys site, over on the left if I remember right! Is tuning your bow, it is O L Adcocks bareshaft tuning info.

     Nock high or low, normally indicates nock point to high or low, and not spine. Best read you will get on bareshaft tuning a bow JMHO. Good luck.

Shorten your fistmele about 1/2" and try it. A low fistmele can make an arrow kick out off the riser to look spine weak.

Hormoan- I have read the bare shaft planing method main times. It was actually first writen by easton.  I have been using both this method and the bare shaft method.  Both indicate a weak shaft with the 2219's, the weak shaft just always showed nock high.  Adjusting the nock point had no affect.

Draco- I think you mean brace hieght.  Bow shoots sweet where it is at, but I going to increase it a little to see what happens.

Please keep the ideas coming, I am stumped on this one.  Most bows I can tune pretty fast, including my other Morrisons.

I bet with that bow and a 28.5" arrow drawing 27"s you will need an arrow that spines around 85#s and that is with 125 to 145 grain head. Shawn

75/95 Goldtips and adjust the tip weight until you get the flight you want.

What Shawn said. Heavier head more spine.

This morning I drop the point weight to 125 grs. and builded out the side plate a 1/16".  Also adjusted my brace hieght from 6-1/4 to 6-1/2.  Now the bow is tuned perfect with a 28-1/2" 2219 using both planing method (out to 30 yards)and bare shaft tuning.  Now I just need to make adjustment to the arrow lenght to use 175 gr points.  The spine charts show this arrow spines at 95# on 26" centers.  I am just surprised I needed this much spine.  Thank you all for the replies.
