[QUOTE="Channel Hopper, post: 1100736, member: 175144"] Before the 900 tons of kit does its usual gravity thing, I would fill the back of the reflector with hardcore and pour concrete into the remaining space. Once set, install whatever rubber/mattresses/cushions are required to break the fall, topping up to the rim with tennis balls or surrounding foliage if necessary. At least when the heavy stuff falls the parabola is a permanent memory of the earlier metal structure , and could be reused with little more than a new surface of modern material. [/QUOTE]
