Title: Narrowed Limbs???
Post by: nlester on February 05, 2012, 09:21:00 PM: I'm currently working on an osage bow that's around 64" long.....Well, I got the brace height to around 5 inches and drawn out to about 23 inches, and it lifted a split on the side between the fades and mid limb. I tamed the splinter which narrowed the limb down to 7/8 inch wide. Is that too narrow for a bow 64 inches long? Will I need to make all the limb 7/8th inch wide to mid limb? I'm hoping to salvage this one.....it has the potential to be the nicest one I've ever made for sure. Just didn't know if narrowing it that much would be acceptable. I'm looking to bring the bow in at about mid to upper 40lb range. Any help would be greatly appreciated. Thanks!

Try starting your next bow with a nice 1/4" chamfer along the edges. That way its always somewhat rounded as you scrape/rasp down to tiller.

IMO every person working on wood bows should mark that comment down in their memory book and stick it on the wall in their shop. So easy and important to do but also so easy to forget and leave undone. Just one omission could be all it takes to lead to an inconvenient splinter, or even a disastrous result.

I'll be in touch sometime Kris. Need to get down there and bring that rock with me. Thanks to everyone who helped. Lessons learned.
