We are on the same page. I bought 3 pairs of Neodymium superstrong magnets OD 2"X ID 1" X 1/4" on e-bay for $72. I put each pair on aluminum axle such as the lower magnet is sitting straight on its shoulder, and the upper one contacts the axle through two rubber O-rings. The rings are taking lateral load, centering one magnet against the other and damping lateral vibrations. The upper magnets bear the sandbox through aluminum cups. The axle lower threaded end of 3/4" is inserted into the hole within massive supporting shelf made of three 0.5" plywood sheets glued together, and fixed by means of two aluminum nuts, allowing the sandbox precise levelling. This platform can bear my own weight (75 kg), still leaving about 1 mm gap between magnets (verified). Work is in progress, I will report about results.
