Laundry Line with Pulleys

Would love to see a DIY plan in Sketch Up with Ana White fan-mods for the Mother Earth News clothesline. This is an old idea -- as old as laundry lines practically! -- but I couldn't find anything like it here on ana-white.com. Help!

Also, where do you go to search through old forum posts? Cannot figure it out!
