Hi there,

       Why are you trying to use steel tape when piano wire is readily 
available and quite cheap? It can give longer periods.

       If you use a vertical rod connected to the centre of the horizontal 
dumbell and clamp sections of piano wire in both it's ends, you can get quite a 
rigid system which does not wave about in the breeze....

       Regards,

       Chris Chapman
