I wonder if anyone here has ever tried using double-side tape for attaching his shakers directly to the surface of a fibre bucket seat, instead of drilling and screwing? It would work, but for how long, after countless hours of vibrations? I'm talking about big shakers like the bs200i, which weight 1,5 kg, and also about top quality tape, such as 3M, Wurth or any other industrial-grade product.
