Definitely going to find it's way into some of my designs in the future. Thanks for sharing. I may even go back and rework my Super Corsair to include this where possible. It's really exciting to learn something new.

Thanks again.
Please post your experience with this technique - I'd be very interested in knowing how it works or how it doesn't. By "hourglassing" I meant the tendency of a paper tube to have the ends greater in diameter than the middle of the tube - similar to what CMAGS had shown. The longer the tube the more this may happen. An hourglass is an extreme example. As CMAGS explained (and understands perfectly), the internal I-beam formed along the lenght of the tube at the seam will insure dimensional fidelity, preventing any hourglassing, as well as making the part much more rigid.
