Well, I'm not impressed...this is a great example of the old adage that a little knowledge can be a dangerous thing. Maybe he knows something about the electrical side of things and his magnesium casting knowledge seems somewhat competent. But by the time he takes a soldering iron to the plastic cases and rants on about the bushing that supports the pinion gear he's just proven to me that he needs to keep his day job because his videos will not pay for his retirement years. He may be funny to watch, but he's not competent.
He's pretty up-beat on most of the other parts. He finds few things to fault other than 1. the price tag, 2. the melting temperature of a motor housing cover and 3. the bushing for the pinion gear.
1. The price tag...ya it's expensive.
2. The melting test...a bogus, stupid test without any merit, he should be ashamed because he knows better.
3. The bushing rant...every automobile made in the last 70+ years with a manual transmission has used a pilot bushing mounted in the end of the crankshaft to pilot/support the input shaft of a manual transmission. It's a simple, fail-safe, proven approach that's still used today. People blow up engines, they trash transmissions and differentials, they replace clutches but very, very, very few replace the pilot bushing unless the tranny is already out. The bushing approach used for the transmission input shaft and the Festool drill pinion gear support is bomb proof!
