A while ago I got a pair of osage billets off ebay. Being a long time admirer of Marcs St Louis's work i decided to attempt a relatively moderate reflex deflex design. Im relatively new to the addiction so i would love to hear any suggestions as I build this bow.
The victims
-
splitting off the belly and chasing a ring then burnishing the back with a small glass jar
-
laying out to 1 1/4 wide at the widest then tapering to 1/2 at the tips. After splicing this stave should turn out 64 1/2 long
-
didn't get any pics of the splicing process. its a pretty basic z splice 2 1/2 long. glued into 1 3/4 deflex with two short maple lams to rienforce the handel. The splice was pretty sketcy and had a few gaps so i mixed some epoxy with sawdust filled them up. hope it holds.
-
put it on the piller tiller 8) made some adjustments and braced. I think the next step will be to heat treat in the reflex ala Marc st louis.
I was wondering what the finished mass should be on this bow
Plans are 63 ntn
47lbs at 27inch draw
handle and fades = 9inch
Heat treated
not sure if i should reduce the limbs some more before ht or what. right now its pulling about 30lbs at 10inches
the current mass is about 27 oz

Looking great so far!!!

Looks like you're doing a fine job so far Moses. I would have been more inclined to glue it up in reflex rather than deflex but if you're makin a RD (or would that be DR - always confuses me ;-) ) then that's the way to do it, then heat in the reflex in the limb. I'd also fill that notch at the handle with a piece of wood cut tight to fit (hope you're not plannin on leaving it there for a cut in shelf or something - not a good idea near your splice joint). You got some good skills there young man!

Hey.
Its been a while but i have made some progress on my bow though I havent taken any pictures. Turns out doing a comprehensive build along is a bit more work than id anticipated. Maybe when i get more experience ill be able to do a good one, but for now im mainly focusing on the bow building part. Since last time i heat treated 1and 3/4 inches of reflex in and glued on some overlays. Right now i have it at a zero brace hight (which creates tons of string tension)
Having never tillered an RD bow before i am not quite sure how to continue from this point.
First pics shows unbraced reflex and the second shows me pulling it about 6 inches where it weighs around 25lbs.
The mass of the bow is 4 oz over what i think the finished weight should be.

You're helping me :-[
