MORE PROGRESS for Part 3 of this quest
I'll be meeting with the NDT manager at Team Industrial Services and will take a barrel donated by a fella here which is a candidate for destructive testing related to over-honing. Decided to do BOTH MPI (first) then radiography to compare the sensitivity for identifying wall defects (hope there is one!)
The cost is $125 for each test. If a defect is found, THEN METL can section the barrel and identify the nature of the defect.
TEAM has international offices and is throughout the U.S.
http://www.teamindustrialservices.com/ IF radiography (which is certainly interpreter dependent) turns out to be both sensitive (if it's there, it's there ie. no false negatives) and specific (if it's not there, it's not there ie. no false positives) that might be a helpful NDT for $125.
