I've got the stave, and it looks like it ought to make a really nice bow.
It's 68" long, a little longer then we typically make our bows which run anywhere from 60-66". Pyramid style starting from 1-5/8" at the fades down 11/16" at the tips. I'll probably make the tips 7/16" and after relaying out, remove the excess limb width from the fades down. The fades are running a little longer also then we generally make ours, so it might be best to leave it at 68", or no less then maybe 66". I can easily make out the cambrium layer, so hopefully it should be easy to remove...almost tempted to use a drawknife but I'll start off with a scrapper and see.
Right now the limb thickness is 1" at the fades down to 5/8" at the tips. Being a pyramid bow, the final full-length limb thickness should be fairly constant from the fades out. I think I'll play it safe to begin with and layout a thickness at the fades of 5/8" down to 1/2" at the tips after I've first removed the cambrium layer. This should prepare the stave for putting on a form and adding a little reflex, but mostly to put some curvature in some flat spots along the limbs. The stave has 2" of reflex now, but not with a consistant curve full length of the limbs. Most of the reflex is due to a couple of short spots in each limb instead of full length.
If the wood (Guava)acts much like hickory, I think we should be okay with what I've discussed. If anyone with experience with guava thinks I should proceed differently, please feel free to speak up or forever hold your peace...cause I'm itchin' to get started!
