I did, but I couldn't find nothing really. They both bent easy with no effort so I didn't think it was the jig at first, but it could of been. I glued everything together on the jig's before I nailed em, hoping it would help a bit to deter the wood from splitting from the 8's I used to tack it all together, as well as hold together a little better. I guess it could of been the glue in the jig? I've had limbs make that same sound, and with no effort at all, just peel apart at the rings on the belly when tip flipping...
