I agree, that is informative. I know these rules but have never seen them demonstrated this way. Thanks.
Very cool. This will help in setting up the driveshaft in the 48. Had seen the rules before but never the demonstration. Thanks for posting

This is pretty standard stuff in Vocational school. We covered it. Phasing is important as demonstrated but also, the U-joints have to "work" also. Meaning they have to rotate to spread the load across the needle bearings otherwise you burn them up and dry out/crunch them up. That's why there are "working" angles in a driveline, usually -/+ 3 degrees in a street vehicle, they can be more in off-road type vehicles due to lifted suspensions as long as they're in phase.
Nice video. I wish they had tipped the input output to the "absolutely not"configuration here - http://www.classiczcars.com/forums/...veline-operating-angles-pinion%20angle[1].jpg Despite the dire warnings about strain and vibration if the angles are the same That one outputs constant velocity too.
In the days before videos were available on most any subject, a rep from a local driveline company had a similar demo unit at a seminar, sure left a lasting impression on me.
Here's the logical follow-up video showing operation of constant-velocity joints.... http://www.macsmotorcitygarage.com/2014/07/31/video-the-constant-velocity-joint-in-action/
Exactly. A slight angle keeps the needles rotating, prevents what they call "false brinelling." It's difficult to get true zero, but possible.
