This thread got my attention because I'm a metallurgist at Boeing. My degree is in Materials Engineering (7 years), and I perform failure analysis and destructive testing of metallic components critical to military helicopters. I would like to know from Slowboy:
1) What metallurgical evaluation is being performed vs what information do you want to prove?
2) What is the experience level of the person conducting the evaluation and what type of equipment are they using?
I ask this of anyone, including Buschur, Slowboy, or anyone else:
- Would you like a 2nd opinion? I can perform this work for free, as I have unlimited access to the laboratory and all the equipment. I can perform the following:
1) chemical evaluations using energy dispersive x-ray analysis (EDX)
2) hardness testing (to determine ultimate tensile strength)
3) microstructure (to determine grain size, impurities or other anomalies)
4) compressive or tensile residual stress using x-ray diffraction (good to see what type of manufacturing stresses were imparted on the component and whether it is conducive to crack growth)
5) many other types of tests depending on what we really want to find.
As an engineer, I like numbers and facts. So let me know if you are interested.

< we all own one on here.. i didnt see a mommy powered honda symbol on here, so quit the whining!

! You think the end seller is making $175 profit?? If that were true, the knock-off would have no reason to exist! It's more like $50-75. And $50/unit to import is way high, too. Assuming a distributor imports a pallet of 50 units, it probably costs about $500 to bring in, including any tariffs/fees/whatever. That's about $10/unit.
