A friend of mine would like to sell me his Portable 360 levitation, similar to the one sold by Tilford. I'm grabbing the chance to get it coz I simply love the effect. However, I wonder if the board can be modified,perhaps by making another board, so that there can be no apparent support under the assistant. That way, I can interchange it, using the board for commercial gigs and removing it and replacing it with the secret board for theater type settings with my own assistant. Has anyone done this before? I was informed of the superior workmanship on the prop and I'd probably manufacture a new board for the 'no board attached method'. Any experiences??
