It definitely doesnt take much bullying before it screws the pooch. the one cedar bow I broke, i took the good limb and steamed it a while to see what erc was capable of bending wise. it look a little bit of curve, but it didnt take much before blowing up on the belly side..lol as far as cedar goes, i will only make very small corrections in the future...just doesnt take the abuse like osage.
now as far as not being as good as osage, the latest sinew backed one i made (1st picture) is a screamer. it stands side by side with my osage bow and probably outperforms a lot of them. it recovers superfast. way faster than regular white woods. its the all sapwood bow. the limbs are so light and it is super snappy. Had Donnie Wilkerson over and he shot my cedar bows as well as some osage bows and he was really surprised at how fast that cedar was even compared to osage. And it's just a straight bow. so after this one, I am really pro cedar sapwood. slow just isn't in this bow's vocabulary.
2nd pic is the longer one that has more heartwood in it. its a pretty decent bow and I was impressed when i built it..but its no osage bow. its about on average cast wise as hickory or elm...just lighter in your hand. still a good hunting bow, but its not that sapwood bow by any means..lol
I'd say build one of each. make a sapwood bow and a heartwood bow and see which works best for you. when you cut it, peel the bark and seal it b\c the borers really like cedar bark and sapwood..lol it really could be a regional thing. i havent work enough from different regions to know. these staves all came from north west Alabama.
