Wadly and I have been thinking through different methods for breaking EPS foam scraps down into the beads the blocks were made of. I’ve seen and heard of all sorts of different methods being employed. One guy used his weed wacker inside the bag. Another stacked about 100 skill saw blades onto a shaft and used that. Another has some sort of shredder (undefined).
We may have hit on a method that will be easy, cheap and effective. We’re going to roll barbed wire onto a metal tube, add end caps and a rod down the center, a large fly wheel to slow it way down and we’ll run it using the motor from the cement mixer.
