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.
