Aaaah... young Grasshopper... well done! I think you're mastering this bow making thing. My young apprentice continues to amaze! It doesn't seem to matter what I hand him, he makes a silk purse from a Sow's ear!
I did get a little aggressive sanding out the fades, but as mentioned, it doesn't take much ipe to make a bow. And as far as maple backing... I've made maple backed ipe flatbows up to 75# with no problems. Good job Cam! What do you want next? I think it's time you made a character self bow. Huh?
