I did my AME apprenticeship in the early 80's with a bunch of WW2 aircraft mechanics. What they could do with simple hand tools or rudimentary power tools was absolutely amazing. When I asked them how they figured out to do "the things they do" I was told when Jerry is bombing the crap out of you and the only thing between you and having to learn to speak German is a serviceable aircraft -- you learn in a hurry.
Best demonstration was watching an old timer weld an aluminum air intake plenum with an oxyacetylene setup and blue goggles.
Unfortunately, one of my mentors went from functioning mechanic to someone who didn't recognize me - in 8 months due to dementia.... Would have liked to have had a couple of years with him to learn more..........

I always took the time to try and learn those little tricks from the old timers every chance I got, and still do! The old ways of being able to get the job done and done well are fading. Not too many people can make honey out of dog poop, but that seems to be my expertise haha.
If I didn't rebuild it, make it or modify it, I get bored with it!
