Thanks for the reply Arvin. I kind of figured you were experimenting for your flight bows. Interested in your findings.

Guys I’m thinking it takes 8 oz of mass in a limb for a fifty pound bow or there abouts. How you distribute the mass will determine the set. Keeping in mind that wood is 8 times stronger in thickness compared to width. I will cut some pieces as close to the same size as possible. I will do this at fade , mid limb and 2” from tip. I think I will do this on several bows.  still need to hang my tillering board but my siding is not in yet. So I may have to hang it temporarily to tiller this bow.

Here is bow I talked Kenny Cartwright out of its 45# at 24”. The mass is 12 oz. bend in the handle bow. I can’t wait to test this little bow. 52” ntn.

[Selfbowman]

Well the bow came in at 20.9 oz. 50@27 shot one arrow between 220-230 several times. Shot a 500 gr arrow 200 plus. It lost half of the reflex from fade to mid limb in set. Good bow. May need to do a stretch test on this bow.

Here is the cross sections of the limbs.

Interesting experiment, Arvin. What weight are you aiming for? I'm interested to see how it works out.

It’s fifty at 27” right now. I’m thinking taking some more off the outer limbs  and tiller to about 48@ 28 and try shooting it there. The mass on my simple composite BBO  that shoots 260 yds is 18.9 oz. This bow is 20.9 oz. The handles are almost identical. I think it’s the thick bamboo backing that is lighter.both bows come in at 50 @27. I think the one ounce in each limb is the difference. I’m open to other theories.

Are the back profiles the same on both bows? Width? Any set yet in tillering?

[Selfbowman]

Marc the profiles are very similar. The bbo has a little less trapping. It has more set in the fades and mid sections but has a bit more reflex at the last nine inches or so. The Osage bow has only been shot 8-10 times. I’ll try to get a pic of one laying on top of the other.

Mark I think the main difference in the Osage bow shooting 20-30 yds shorter is the bamboo backed has less mass weight. 2 oz is quite a bit.

Pretty impressive looking osage bow. Looking forward to see it finished up. Can't recall how long ago, but remember a post you made about adding reflex only to the outer limbs. Because of that post I made a new caul and been doing that when practical. I sure do like how bows like that shoot. It;s also easier to gauge set in the inner limb. Thanks and good luck with your goals for this one.
