I built a sprung basketweave floor based on ballet floors for leaps and kettlebell swings. There are four layers of sleepers, a rectangular frame to keep everything together, and the 3/4 plywood on top. I posted pictures on the facebook page just now. It works great, actually! Problem is, the sleepers move around. A dance floor guy told me not to try to nail or screw the sleepers together because the nails and screws will 'back out'. I've been struggling with this issue for almost three years.
