About 8 months ago I was given 3 Osage trunks 3-4” in diameter. I band sawed all 3 in half. Debarked one and left the bark on the others. Sealed the ends with titebond and the backs of the debarked with PU. Strapped the half’s back together with wedges in between. All the staves have cracked along the belly (see pic), and the debarked stave cracked along the back and the belly. What should I have done different? Are these staves ruined?
