I cheat when I make bows. example, I ordered a very custom half breed blank from Craig, the finest dark yew lams I have ever seen. I was attempting to make a 68" 26" sweet spot longbow. 57.5 at 26" and 60 @ 27". The best shooting longbow i have ever owned, my grandson has it now. It came very large, Craig did not want to over floor tiller it. I used power tools like i did with the yew blank and the laminated bows that i built years ago. I used saws, power grinder, and power sanders to turn that free chunk of super dry pignut into a bow. Not recommending this to others. I have built 48 houses, two classical guitars, and buildings that you could not fly a 737 through, i understand power tools, not so much those two handled draw knives are a mystery to me, but I bet they work better.
The pignut is still 64" long. I shot it again last night. I killed my foam deer at about 18 yards ten out of ten with one of these with that bow, it seems to really like them. 45 spine 27" Wapiti tapered bop Schulz original Hunter's Head.
