In Response To: Re: WoodenBoat Bird's Mouth Paddle Shaft (Rehd)

Hi Rehd, There was the slightest amount of mis-alignment in the rabbet when I twisted it. With a straight shaft, no separation, whatsoever.

Yes, there is a pre-stress, but it puts the epoxy joint in shear where it's relatively strong. I don't think there's enough stress against the strength of the epoxy to cause future harm.

With my old twisted solid lamination paddleshaft, I just have a bit of delamination, but that was due to a failed epoxy coating on the shaft. I (hate to admit this but..) used white glue. I'm actually impressed by how well it has held up. If it hadn't been for the too-thin epoxy coating, the glue would probably have stayed dry, and no delamination would have occurred. I put a bit more faith in epoxy than white glue.
