Ran across this guys channel while link hopping not long ago. He's pretty darn hilarious to watch, due to his pretty unique use of the english language. He's a cannuck, so the usual rules apply :D.
But honestly, the guy is pretty darn smart. He is a semi-machinist / repairman. He does alot of how-to type videos, does alot of electrical tool tear down and repair. Most of it is pretty darn funny.
He does occasionally use some strong language at times... so dont watch while the misses is around
Here's a good one to start with... I thought it was pretty clever, and funny as heck.
Fixing a Stripped bolt hole:
And for giggles, continued testing of the above fix.
He has some useful things on stuck bolt removal techniques... removal of bolts with broken extractors in them (LOL!), removal of broken taps... all kinds of useful things.
Anywho just passing this along. Its pretty funny to watch on a rainy, lazy sunday.
