Osage backing for ERC?

(1/3) > >>

Stickhead:
I’m close to committing to putting 1/8th inch strip of Osage over an ERC roughed out bow (about 50/50 heartwood/sapwood).  Anybody ever tried this combination?  My last experiment, a hickory backed ERC, blew up.  But the hickory was questionable, so I’m hoping the Osage will have enough tension strength to hold it together.

Yeah, I know, you want me to back it with sinew, but I’m not ready to go that route yet.

I think I'd back an ERC bow with osage sapwood but I don't know about a 50/50 combo. Elm or maple might be a better option. IMO

I meant that the ERC is 50/50, and the Osage strip would go on top of that.  The Osage strip is 1/8” of heartwood.

Kidder:
Would you be thinking of a single growth ring on the Osage or decrowned?

Neither.  It’s edge grain, cut perpendicular to the rings.  The lines run pretty straight.
