I just realized that if I put some EMT (metal conduit) along the top of the sides for a ways, I could slide in some smaller pipe that was bent into a big 'U', and make a wide handle to dump it with - just unhook the rope, slide out the handle and lift! Of course, the henadle would have to be made so it wouldn't slide all the way out when you had it lifted, or you'd drop the back edge of the sledge right down your shins (yipes!)
