Title: Three under barshaft tuning with Bear KM
Post by: Retnuh Wob on September 17, 2012, 11:16:00 PM
I have a 46# 1965 Bear Kodiak Magnum. I have tried several times to bareshaft tune it but the shaft always ends up tail high no matter how I adjust the nock point. Could this be because it is tillered for split and I am shooting three under.  If I built up the shelf with some thick leather would that help.  

I am fairly new to trad shooting and am still on the steep end of the learning curve. Any help would be appreciated.

Mark

A consistently tail high situation can come from a loose nock fit on your serving.  You can tighten it up with some dental floss.  Give it a try and see if you find any improvment.

Thanks Ferret. I'll try that and post how it worked.

Terry,

Sorry for posting on the wrong forum. I wasn't sure but will know better next time.

I appreciate your efforts to keep this a first class site.

Hope it helps you out. Maybe some others will chime in with ideas as well.

Try a 2nd tied on nock below your arrow nock, that can help as well, keeps the arrow nock from sliding down the serving at release.

X2 on the second nock. On a short bow like thatthe string angle is sharper and a loose-fitting nock can slide down the string upon release causing wierd flight. Also, a 52" bow isn't the easiest thing to shoot well, even for an experienced archer with feathers on his shafts. Pay real close attention to your release and consistent weight distribution between the three fingers. I too have a '65 KM 48#. They are the best.

I shoot my Kmag three under as well, and didn't have much luck gettin it to tune well until I used a stick on elevated rest. Give that a try if you aren't totally against a rest. It sure made mine more forgiving and I don't have to set my nock point so high.

Thanks all. I am going to try your suggestions this weekend.  

Limbshaker,  I was wondering about a higher rest.  I put on a thick piece of leather that I skived at the front and back to raise the point where the arrow rests and give the shelf a bit more radius.  If that doesn't help I'll try an elevated rest.  I really like this K Mag.  It's a very pretty bow and seems to really put some zip on an arrow.  I also like the fact that is is so light as I like to backpack and it seems like an idael bow for that. Even though a short bow may be more difficult to shoot well I think it worth learning how.

X 3 on the second nock. I had the same problem with my Grizzly. I also added a piece of toothpick under the shelf material.

Well, I tried a little bit of every thing.  I built up the shelf with some thick leather and skived the ends to give it more radius. I then got some dental floss and built up the serving under the nock to get a little better nock fit.  While I was at it I wound more floss under the area below my arrow nock to creat sort of a lower nock point. Still not quite where I want to be but I'm much closer with my bareshafting and the bow seems to shoot a little better as well.

As I experiment I might try raising the shelf even more, or try an elevated rest to see what effect that has.

My wife likes to use Glide dental floss which is super slick, so I highjacked some of that.  It holds the arrow secure and seems to release it cleanly as well.  And, as a bonus, when I come to full draw, I get a hint of minty freshness lol.

Thanks for all of the tips!
