Okay guys, here we are one month later with my ERC stave and the time has come to cut it to rough shape. And I got to say, it is shaping up fabulously. And even though I might sound crazy saying this, I think the girl actually WANTS to be a bow. For example I was carefully whacking away at her with the hatchet when all of a sudden I go a little too deep and a fair sized strip peels away. Of course, instantly I panick. Doing my best to stay calm though I sight down the stave to see just how much damage I did. AS it was I did none amazingly. In fact that strip peeled away was a good thing as I had gotten a little out of canter in regard to being straight and square. Not saying I am reckless or anything, but this example occurred at least half a dozen times, all the time getting me closer to the desired shape and thickness. She even seems to let the shavings fall right off of her.
Like I side, perhaps I am a bit nuts, but after seeing how she responds to a rough shaving, I can't wait to see her perform as a full fledged bow.
I do have a few questions though in regard to the specific dimensions of the bow. Right now the width of the bow on its belly is 1.75" across, and just nearly that from a side view. (for totally winging it by eye, I impressed even myself how close to square I got the thing.) The over all length is 59.5". I mean to make this bow for a young friend of mine, due to the initially short length of the stave when I cut it down. Fortunately for him his draw length falls right in the sweet spot of the bow at 20.4".
The part i need answers on is limb dimensions. Foremost is there some sort of equation o formula I can use on my own for later use, or is it something that is more or less guessed upon based on the wood and the experience of the bowyer? How wide and how thick should the limbs be? What of handle to limb taper? I don't know about poundage yet, but definitely nothing more than 25-30#.
Unfortunately I do not have pictures of the stave roughed out yet, but I will get them and post them whenever I can. As always thanks for your endless help. Without it I would have only firewood and kindling. Thanks a million.
