Thats cool Frank, hope it works out for you. I've made unbacked Osage bows 58" long that draw to 29" with out a problem. It's very dense resilient wood.

ryan i know it's absolutely no problem for the wood, but hey a short snakey bow with flipped tips ...it's only my third or fourth stavebow ...and i blew an osage recurve a year ago while tillering; the wood is REALLY expensive over here...

had to make a jig to evenout the reflex. still after that my lower limb was a lot stiffer at same width and thickness. but now i guess i'm fine. her is the stubborn lady braced and at 26" pull. - the marked area i believe needs a bit more bending. what do you all think?

at the moment i have a really light lower limb and a really dark upper limb on the bellyside. - would it make sense to heattreat the lighter limb right before sanding??

thanks for watching again, really appreciate your help!

ps: i'll probably pike her by two or three inches when the tiller is finished. - how much draw weight will that add?? (she'll end up at lower 50s)

Looks like you have the tiller figured about right,where you have the right limb marked.Usually it will add about 3 lbs. per. inch,at least that has been my experience.Flipping the tips and heat treating will add at least 5 or 6 lbs. Looking good.

thanks pappy! had a few more strokes at that area and really became better; getting more and more excited about this, wish i had more time to finish the bow! ...but soon anyway...

pappy, do you think more heating would harm the bow??

do you think if i shorten the tips i could possibly flip them a bit more???

thanks again, frank

Man, just read through all this Frank. That has turned into one fine looking bow! I believe Hillbilly's right, your most likely going to get a goodun out of this

. Can't wait to see the final outcome..

I don't think it would,I usually don't heat treat or flip the tips till I am out to 18 -20 inches of draw anyway.I straighten and put in some reflex before I start tillering and then the tips and heat treat
at 18-20 or sometimes at about full draw before it is shot in..Seems to work fine.

the lady gained some weight...

piked the bow by two inches (66 ntn now for my 29"pull) and flipped the tips some more which worked out great; this i did yesterday in the evening.
today i braced her to check the tiller a bit and see how the string lays and i'm totally amazed how the limbs just never go sideways eventhough there is quite some snake in the upper limb and the string is beside the limb a bit right at the upper nock (ryan i guess you are right: osage IS better

...) (...and pat is right, too: the snake should be in the upper limb, so you can look at it!).
so i pulled and scraped for an hour and got her to 26" where she has 52#. 3" more to go and she should be right around 60# hoping to end at 55"-57" after shooting her in!

that part mid of right/upper limb still looks stiff but it has serious action when i pull the bow. probably rather leave that alone.

any comments??

thanks for watching, frank

ps: the pull on the picture is about 25"

Very nice Frank. You did an excellent job on that bow. How does it feel in the hand when you pull it back, does it pivot back and forth or does it stay steady?

Applause! Well done! Jawge

Was it me - I'd go no further! That looks perfect

hey guy! - thanks for the comments!
i'm really pleased with the result and i became more and more confident while i was working on the bow (which was a loooong time

)
mark, the bow doesn't pivot; felt stable basically through the entire process of tillering after a certain balance was reached.

will pull her a bit further and than form out the handle and shoot her in!

thanks again, frank
