SN SN SN SN SN SN NS NS NS NS NS NS instead of SN SN SN SN SN SN SN SN SN SN SN SN In the first arrangement, the arrays from two linked SMOT ramps will attract each other and in the second they will repel each other. The lower array arrangement is the one I use for linking. However I have experimented with the first, but not too far as the magnets from both arrays attract each other and lift off the side magnet supports. Using the first arrangement, I got much better linking results, the second linked ramp actually assists with the ball climbing the first ramp. But I went back to the second as I thought it would cause less problems overall. But hey, experiment with the first system. Just devise a way to hold the magnets to the magnet supports. Blu-Tack ......... why didn't I think of that! Greg - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Horace Heffner http://www.mtaonline.net/~hheffner/
