have fun.
We call american hornbeam musclewood. I made a bow of it back in feb. Is the bark off,if its not and the stave is green then get it off asap. If not then its a real b!#$# to scrape the bark of because of the ridges and valleys along the back. Use a gooseneck scraper if you have one. And be careful not to nick into a ridge and violate the back.
I love my musclewood bow. Its prob my most accurate bow right now that will be one I take to the woods this fall. It responded well to heat treating too. Its some tough gnarly stuff for sure.
Let me know if ya have any more questions. Yours is gonna have to bend thru the handle. Mine is 59" ntn. My bend comes up thru the fades. And I can just "feel" a slight tension in the handle right as I hit full draw. And follow that grain of the muscles. You'll prob have to heat correct for sure. There's no such thing as a dead straight full stave of american hornbeam.
