Good deal now as soon as I split my staves. I add a coulpe inchs of deflex. Put on saw horses and ratch strap the middle of the stave to the flood. O'sage I add 2 to 3 inchs. I've a beleiver the older osage the better the bow can be if you do your part.
With a stave seasoned a few years old with 2,3 inchs of deflex. My osage bows finished will hold anywhere from a inch deflex to straight. But you never know wood is wood.
I never build a osage thats not well seasoned 5 to 20 years. Not that you can't fourm it down to bow size and finish it off in a hot box.
You can debark but if you remove the sap wood you have to seal the ends back really well. I just leave mine ratched down for couple years. Then you can just stand it up and forget about it for a few years.
I leave the bark and sap wood and just let your staves season with time.
SLOW ALWAYS BETTER WITH SEASONING AND TILLERING.
