I was doing some testing on my prop a few days ago.  Set up a timing light on a tripod with a camcorder.

Enjoy.

Prop tip. Watching how it tracks and monitoring it for pitch fluctuations at various RPM.

Looks like two blade thickness out of track.....and a very slight pitch difference or side to side unbalance of engine crank...
