Congratulations on the bow holding together! I'll highly recommend seeing if you can hook up with someone around you that have tillered a few bows. Nothing like real life experience to make your learning curve exponential. I started similarly. Made backed ipe bows. Got some successes. But, it wasn't 'til I found a mentor and got a stave that things really took off.
Good for you, enjoy the journey!
P.s. I see you are in Nevada, you have Juniper around? What kinds of trees you got growing out there?
