I've wanted to build a walking dragline that looks like Tow-Mater from Cars for a brief while now. And how easy it was! I just went out and bought the LEGO Tow-Mater kit from the LEGO Store for $7, threw in an old bag of brown bricks I've accumulated over the past three years, and wah-lah-- Tow-Mater Dragline is born! It only took about three hours total from start to finish, once I figured out the scale I was looking for. Although not modeled after a specific machine in the real world, this dragline would be somewhere between the size of a Marion 7400 and a Bucyrus-Erie 1250b. Look at the "glass" of the operator's cab to get some idea of the scale. Happy Holidays!
