dwmccloud, just was thinking about this ... it sounded like from one of your earlier posts that you missed that the "sage" limbs are from a samick sage takedown bow. Sorry if I missed something.
As for makign them out of wood, honestly I don't recommend it. I've made a couple all wood takedown's and it's not easy by any stretch of the word. If you have to ask if it can be done, then you're probably not ready to do it.
So far I've had 3 all wood takedowns survive. The first was all red oak, 62" long with a 12" riser, which took massive set, looks liek crap, and is basically a wall hanger to remind me to be patient on my finish work. It's maybe 30# @ 25".
The second is a 64" recurve, 14" riser limbs are hickory back, maple core, and jatoba belly with hickory wedge, riser is maple and jatoba. It's pretty nice, but it took 3 iterations of the limbs to get it right. It's about 40#@25".
The last was a 68" R/D longbow, 14" riser, limbs were hickory back, shedua core, jatoba belly, with hickory wedges. Riser was maple and shedua. This was a very nice shooting bow, didn't take too much set. Not the fastest thing on the planet, but probably longer than I needed. This bow was right around 50# @ 27".
So long story short, yes it can be done with all wood, but this has literally been a saga for me going on two years now to get the formula right, and I still have some ground to cover.
These are not short bows, and they have very short risers. Theres alot of limb there. My guess is on that riser (which is probably 19-21") you're going to NEED a 68" or longer bow if you make wood limbs.
Also since the limb pads are deflexed, you're going to need to make some kind of recurve or extreme R/D limb profile. Honestly I think you're biting off too much in one shot.
Drop the $80 and buy the samick sage limbs, they'll serve you well. And frankly, unless you have alot of tools and scrap wood, it's gonna cost you $80 and take 100 hours of work to get those wood limbs together without any remote guarantee of success.
