Here we see a typical oil well and "nodding donkey" pumpjack rendered in LEGO form, ready to start pumping crude oil. (link to Wikipedia for more on pumpjacks, in case you don't know what they are.) The oil well design was heavily modified in design and usage, as it was originally designed as the lower half of a water tower for steam trains! The oil pumpjack features a crank as a play feature, (which could easily be motorized) though it doesn't actually pump anything. My video from Flickr showing it in motion is being stupid and won't embed, so here's a link to it instead. Thoughts? UPDATE 7/10/23: Model finished, real world photos added to main post!

Nodding Donkey After the fun I had with the Chinese Laundry and the power functions I had to build something that again 'moved and shaked' and with the recent decline in oil prices I thought a Nodding Donkey would be an interesting build. If you are unfamiliar with these they are simple pumping mechanisms that are used to retrieve Oil or Water from underground. The product is then either stored locally in a tank or piped to a processing plant. I built it in a modular format so that it could fit into my City. The 'A' frame is made of four Technic bricks that in turn were wrapped in tiles to cover the holes. Here's a shot from the rear showing the storage tank and the mechanicals A concerned local citizen has noticed oil leaking from the well head. Here's the details of the step-down gear box that I built to slow the m-motor down to a point where the Nodding Donkey looked more natural and less like a bucking bronco. And finally a link to a short video of the machine in action. I placed the m-motor on the ground floor of my Downtown Museum/Noodle Shop and ran the long axle through the adjacent wall. https://flic.kr/p/qaZuhE I hope you like it and as usual comments, criticism and ridicule are most welcome!
