Barrel Wall Thickness
Back to the original topic' if someone can find a good wall thickness gauge we can probably measure 20 or more barrels at the HQ tent at Pin Tail

John's math is of Einstein caliber-
That is why the welding rod is rated at about 10% higher that the UTS of the base metal(s) being joined by the welding process- SMAW- MIG (Metallic Inert gas) wire welding- most of the .030- .050 range filler wires used (with copper flash coating for greater current conductivity) at at a 70,000 UTS range- I don't know John Mazza from Adam's offside ox, but I'll bet he is a student of Hooke's Law--
Austin- I suggest you contact PGCA lad Jon Bosford in Ann Arbor, MI- he was at both Da Yooper shoot and the recent Lapeer side-by-event- if he is coming out to Pin the Tail on Da Point in Sept- he'd be your "go to guy" on barrel wall thickness gauging- Last edited by Francis Morin; 07-30-2010 at 08:17 AM.. |

The engineering education occasionally pays off... (It also makes me over-analyze everything !) |

Anything man-made than can fail- needs "over-analysis" |

Hooke's Law, Occam's Razor, the Pythagorean Theory, Newton's Laws of Gravity- all bow down at the Altar of Murphy- when it can go wrong, it will- Three disciplines intrigue me to no end (I barely got out of HS and into the USMC- many years ago now) they are: Classical Music, Architecture and Metallurgy- all involved with higher strata of Math- I have nothing but respect for the engineers who design and then oversee the build- as we used to say in the Fab Shop[- "If they can draw it on paper, we can build it in metal to print- time after time"__

Likewise, I have encountered some fine craftsmen with amazing insight & skills. In fact, I have the honor/pleasure of working with such a person on a major project in a few weeks. It's times like this that I really enjoy coming to work ! |
