I'm kinda newbie too. Already broken 4 so far...this year... well, I over tillered two, broke a limb overstraining one on the tree, and the 4th just didn't work so I did the breaking. BUT... I sure learned alot about splicing, and backing, and tillering, and tip overlays, and handle shapes, and scrapers, and rasps, and......
Now have three board blanks spliced up, one w/kraftfiber MDF backing, two linen backed, and two small ones for my daughters all profiled. Maybe one of these will work out.
In the meantime, I've learned how to flemish string, two and three bundle, made a fletching burner from an old model train transformer, an arrow taper jig for my disk sander, retuned my bandsaw, and managed to seriously strain my shoulder with a friends overweight long bow.
There's more to this than just the bow. You gotta have something to shoot with it. Got some elkhide for arm guard and a friend 'says' he'll get me some splits to weave a basket quiver...?
Just keep on and sooner or later you'll get it right.
