I've not worked with black locust before. The tree I cut this AM seems to have 2 different types of ring structure; The larger rings are 3/8 to 1/2 inch wide, and there are 2 light (sapwood) rings and several dark (heartwood) rings. These have a crunchy layer between them, ala osage. Within the larger rings are about 10-12 smaller diameter rings that are nearly impossible to follow, and don't have the crunchy layer (winter growth?). Please tell the the larger rings are the ones to chase ???

I didn't fallow that very well. I'm kind of slow, how about some pictures. Justin

I think you are seeing the lunar rings inside the annual rings. The annual rings are what you want for a back ring(lunar rings are included). It is the crunchy early ring that you don't want shining through the back. A little of it on top is no problem. 1/2" rings are a bit big. 3/8" is good. I find BL to work very similar to osage but you should to add 10% to the width and length with BL for a similar osage bow.

Those are lunar rings. They are laid down monthly during the growing season. The annual rings are as big as I've seen with BL. Pat

Yeah, they're huge! Thanks Pat. Need some ERC? I'll swap for some sourwood shoots ;D
