Selfbowman:
See if y’all can learn me something about the lunar rings. This is some cuts off the end of a stave. Several things I want to ask about. 1 being most of the late rings there are
about 8 lunar rings to a late ring.2 Does the early rings make up the rest of the lunar cycles? 3 Does the early ring happen when the tree goes dormant? That’s it for now.

If I'm not mistaken...the rings are laid down from the bottom up(or inside out) so the early rings are actually the last rings laid down as the growing season evolves. The lunar rings are only indications of the yearly growth from month to month.

Bob Barnes:
Arvin, I'm not smart like the other guys that help you, but the 'lunar rings' really messed me up a few years ago... I bought several 'awesome' osage staves at OJam a few years ago, and i think you was there that year.  They rings were over 1/4" thick!  When I started working the back, it was like thin clouds of spring growth mixed ll in with the summer growth...and very hard for me to follow since the 'punky' spring rings were very close together.  They were what I think you may be calling lunar rings... I had never worked so hard to chase a ring.  I later found out that it was black locust...and that the thin rings were typical.  Your picture doesn't look like the normal osage rings that you use.

Selfbowman:
Yes this is typical of the Osage I use but this stave Varys In growth ring thickness from one end to the other. Not my favorite stave but will work to make a good bow. Usually one end of the bow ends up thicker. Maybe some one can shed some light on that.maybe additional early ting mass will require more thickness.
