Still plenty of them around, but they like to be called Factory Trained Technicians
As a former 'Factory Trainer' I do understand the comment as used today.
There was once a time, prior to ... oh, around 2000 and the popular invention of the DVD. Long story short; factories and repair shops found it cheaper to give a 'future technician' an "Instructional DVD" to take home and train themselves, earliest version was called "On Line Courses". It would take too much typing and time to explain it all in detail so to cut it short: many (I would even say Most) 'Factory technicians' today have No actual "factory training" at all nut instead sat at home or at the office and watched some videos, maybe (and I emphasize 'Maybe') a little hands on, if any at all, and then they 'Guess' their way through the 'Certification Test' (sometimes they are even just given the answers to speed things along).
The day I was approached and told:
"We don't need Instructors anymore, ALL the information can be packed on a DVD, ALL the questions and answers a trainee could think of can be put on this DVD; gone are the days of the Class Room".
The choice words I had are not for those who wear a skirt nor for a forums with rules against!
AND the things I have seen since, the things I have had to clean up and fix while following behind these 'Shade tree techs' and 'Bubba techs' of today...makes me so glad to be retired now.
*end of off-topic rant*
But I would say that while some on this forum say they would Not want to be next to one pulls nipples, vent liners, and this so-called "clean out screw" for fear of a BLOW OUT....I would have to add that I would Not want to be next to one who Does Not properly and fully maintain their firearms, for those Screws, Nipples, and Liners that have never been pulled, inspected, and maintained have all been exposed to Heat, High Pressure, etc from the Inside and are also candidates one day for BLOW OUTS.
It's a never ending circle of conundrum...is the one on my right a Bubba Tech? Is the one on my right a Slacker who Neglects? Are these firearms all around me potential pipe bombs ready to blow?
Oh well, I gotta stop now, got things to do so I can go shooting next week!
