Wow brother, and good timing. Now that some remuneration should be arriving  I was ready to take more barrel segments to METL for tensile strength testing and composition analysis; to do both requires a 4-5" segment. Thanks! PM sent.

Drew,
Sounds like I'd better pack up your tubes and get'em back to you. I'll be sure to send the other testing segments like the 2-iron Laminated, Fluid Steel, and the percussion tubes along as well.
Congrats on getting your articles published.
My next run is starting coming together, I'll send a PM with pics to you and Steve regarding what exactly we're trying to show on Steve's pieces, so we can all be on the same page.
Regards
Ken

Please do Bro. Ken. I want to get the additional segments to METL this summer Parts 2 & 3 will be a discussion of a barrel rupture with the first (to my knowledge) published photomicrographs of a pattern welded barrel. 4 & 5 will discuss the Birmingham Proof House Trial Report of 1891 and tensile testing of Crolle, Damascus-twist, Twist and several early 1900s new fangled steel barrels, including Armor steel. http://docs.google.com/document/d/1dnRLZgcuHfx7uFOHvHCUGnGFiLiset-DTTEK8OtPYVA/edit Afraid the remuneration will take 4 or 5 articles to cover the almost $3000 I'll be in the hole to METL. But expiring minds want to know

Drew, Do you need more tubes to test? I have a set of damascus barrels, c. 1886, in bad condition. Happy to send if that helps. Thanks for doing this great work.

Thank you Rich. With Dave's high grade crolle segment I will have an adequate sample of crolle, damascus-twist, and twist barrels. And BTW: tensile strength has been remarkable consistent. METL's fee for machining and tensile testing is now $55 and spectrographic (composition) analysis and interpretation is up to $85  My long suffering spouse would like to see some return on this investment in resources What I WOULD like is a segment of Bernard II, and Hunter Arms' Crown & Nitro Steel.

Drew, Unfortunately, the tubes I referred to are crollé. I would be happy to contribute to any fund to support this great research.

Excellent article Dr. Drew...I learned much about Damascus barrels and added to previous knowledge acquired from Professor Joe Wood. (I have learned not to mention Damascus barrels around Uncle Joe as he will immediately launch into a dissertation and the ensuing recess from shooting will be lengthy.)

I recommend Prof. Wood's dissertation on the Birmingham Proof Trial regarding Laminated tubes. His analysis was that the results were skewed towards Laminated being stronger because one of the three sets lasted an inordinate time before deformation (the other Laminated tubes were comparable to other types of tubes).
I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.

Prof. Joe was talking about publishing a review of the Proof House Trial. Did I miss that? Some infro. here https://docs.google.com/document/d/1dnRLZgcuHfx7uFOHvHCUGnGFiLiset-DTTEK8OtPYVA/edit Important to recognize that c. 1860s and c. 1890s and the Phase 1 winner "English Best Laminated Steel" were 3 very different products.

BTW: the late John Brindle, author of Shotgun Shooting: Techniques & Technology published a review of the Trial as part of his 5 article series in The Double Gun Journal, “Black and Nitro, Damascus and Steel” in Volume 4, Issues 2 & 3, 1993 and Volume 5, Issues 1, 2 & 3, 1994.
