Just yesterday I was working a narrow osage stave and when laying out the thickness noticed a hairline ring separation. Luckily, I was able to go down 2 more rings for the back. Now, my problem is (since the limbs were already narrow 1.1875 I'm not sure I have enough thickness left on the belly to obtain my desired draw weight as the stave is 55". I'm thinking about backing it with elk sinew. One hidden flaw and the game plan changed drastically and quite possibly won't yield a bow. I've only built a few bows so I'll chalk this one up to a learning experience.
