Al,
The strobe idea is a good and useable idea and deserves positive feedback. Any idea that can be implemented by those not in possession of a physics lab are great ideas.
Get an adjustable strobe from RadioShack or its ilk. About $20. They're cheap, because they're not powerful, but you don't need a lot of light.
Yes, the prop is dangerous, but you don't need to stand next to it to see what is going on. The RatShack strobes have reflectors that direct the light. Do the test at night, and just hold it over your head as you stand a few feet away, slowly adjusting the flash rate. Don't just pay attention to the muffler. Fuel lines, motor mount members, skin panels, alternator brackets...lots of things will vibrate from a little to "oh my!". Some you may not care about. Some may send you running for a reinforcement. Here's an idle thought that just popped into my idle head. Knowing the flash rate that the muffler is vibrating would easily lead to it's natural frequency...which could then be used for some effective muffler designs?
