It's a great buildalong indeed...Props for sharing Mac.
I was thinking about making it the easier way to reduce the amount of the material needed...while carving one from a log or a block of laminated boards might be more period...steaming some veneer/pressing over the form and then laminating them(similar to how they make skateboards) would be awesome. Bringing lamination process into this opens lots of doors actually. Making a Micarta quiver is another option, or *gulp* - fiberglass.
Also I've become fascinated with vacuforming after making some mouth guards at work...Kydex as a core would be super quick, but then again also super modern.
Don't hate me guys, just throwing a few ideas around.
Jokes aside with all the modern thermo/vacu/forming/laminating/etc. How about this?
Cut the boards with a taper jig attached and blade tilted to a degree...may be a few bisquit joints here and there? Looks like I'm get a medieval cookie?
