Although I understand 10% of what he says (and 1% of his jokes), I've learned a few things from AvE, e.g., how to identify the various kinds of plastique and their application, or what makes some materials (metals) rust (oxidize) and others not, and about mrpete222's channel, of whom I became a fan.
At first I didn't like AvE's videos, because he sounded to me like those kids who enjoy destroying things for no apparent reason.
His attempt to convert a drill press into a poor-man's mill ( " "IMPOSSIBLE!" Milling Machine from a Drill Press ") changed that. I still laugh every time at 11:16 min.
I find his content amusingly informative (translation: he shows what not to do in the shop), even though he occasionally jumps the shark, like at the end of the video down below me.
So I decided to tear down a drill of an almost identical model. The difference is that mine was not in a pristine condition as his, had many problems with previous tinkering, and the motivation was to evaluate a possible repair.
