Hello again everyone and thank you for all the replies. My arrow shelf doesn't need to be center-shot, but I just think it's nice to have one. People keep saying that if you're going to cut an arrow shelf, make sure you "have enough wood in depth and behind the shelf" or the bow will break in the handle, but very few actually give dimensions of what is acceptable for the amount of wood that has to be there for it to be safe. I have made bows in excess of 70lbs without a shelf for years, but the reason I want a shelf in a high draw weight bow is because I want to challenge myself and see if I can do it. It would be nice to have a permanent place for the arrow to rest as well. Problem is that I do have a really good stave that I am working with, and it is very straight with no knots, so perhaps i'll go with no shelf for the draw weight i'm looking for. Perhaps I'll cut in arrow shelfs for lower draw weight bows, but i'm not sure yet. There was a time when I made a 90# hickory backed white oak that I cut a shelf into. Problem was that when I cut the shelf to center, I got back to 29" and it failed near the shelf. That bow was 72" as well, so I guess you learn from your mistakes. If I cut a shelf into this bow, it will probably not be quite center-shot or not have a shelf at all. Also, since I really want to aim for 85# and I love the full compass tiller, perhaps it would be better to just do another "warbow-like" bow like I have done before where it bends in the handle. Just not sure any more, haha!
