There is reference to my suggested experiment here.
A Japanese researcher rotated a heavy steel bar at about 30hz and 
detected the gravity waves at up to 10 metres away using a resonance 
technique. Torsion balances were also used.

What about measuring the pressure of light using mechanical resonance 
methods? The energy required to cause a fine wire to vibrate at its 
resonant frequency in vacuum is extremely small. Vibration of a flat 
ribbon bombarded with laser pulses might be detectable..

I can't see much difference between the gravity waves from an 
oscillating mass and those of GR. The former will die out very quickly 
though because of the contribution of the inevitable balancing mass.
