I need a working scale model of a metal windmill that can draw between 10 – 50 litres of water per hour from a shallow well. The look should be clean and purposeful—something more involved than a basic toy yet not an intricate showpiece. In other words, a moderate-complexity design: sturdy, reliable, and realistically engineered without unnecessary ornamentation. Key points to keep in mind • Material: all major structural and moving parts must be metal. • Capacity target: 10–50 L/h under a steady breeze (please state the wind speed you base calculations on). • Size: small enough for desktop or garden-demo use; I’m flexible here as long as it meets the capacity goal. • Drive train: open to gearboxes, direct crank arms, or other mechanical solutions—efficiency and durability matter more than style. • Power source: wind only (no hidden electric assist). Deliverables • 3-D CAD files (SolidWorks or comparable format) • Detailed engineering drawings with dimensions and tolerances • Complete parts list specifying metal types, fasteners, bearings, seals, etc. • Assembly guide with step-by-step instructions and photos or renders • Basic performance calculation sheet showing expected flow rate vs. wind speed • Short video or animation demonstrating mechanism operation (rendered is fine if physical prototype isn’t supplied) Acceptance criteria The design must pump at least 10 L/h at the stated test wind speed using a 1-meter static head. All files have to be ready for fabrication with no missing dimensions. If you have past examples of small wind-powered mechanisms or pump systems, sharing those will help me understand your approach. I’ll happily answer any technical questions so we can get this model spinning and pumping smoothly.

Hello This is Mohand, Mechanical/Structural engineer. I can develop a practical, fully mechanical metal windmill model capable of pumping 10–50 L/h from a shallow well, with the design optimized for reliable operation, fabrication, and a 1 m static head. Scope of Work: ☑️ Develop the windmill rotor, shaft, crank/gear mechanism, pump assembly, frame, bearings, and well connection ☑️ Size the system around a clearly stated design wind speed and calculate expected flow, torque, efficiency, and pumping performance ☑️ Prepare detailed fabrication-ready CAD drawings with dimensions, tolerances, materials, fasteners, bearings, seals, and component specifications ☑️ Provide complete BOM, assembly instructions, performance calculation sheet, and rendered mechanism animation demonstrating the pumping cycle I’ll keep the design moderate in complexity—sturdy, functional, and suitable for a desktop/garden demonstration without unnecessary ornamentation. The final design will use wind power only with no electrical assistance. Please provide any preferred overall size limits, well diameter/depth, and target design wind speed if you have them. I can then establish the rotor and pump dimensions and develop the initial mechanical concept. Best Regards, Mohand

Hello, I reviewed your windmill requirements, and the core challenge is balancing rotor torque, drivetrain efficiency, pump displacement, and structural durability so the system can reliably achieve the required water flow at a defined wind speed and 1 metre head. I would develop the mechanism around calculated wind torque and pump requirements, then validate the drivetrain, bearings, crank or gearing, materials, and fabrication details through CAD and performance calculations. I have worked on similar mechanical product design and working mechanism projects and can share relevant examples once we connect in chat. Also a quick question, do you have a preferred pump type such as diaphragm, piston, or reciprocating pump, or should that be selected based on the required flow and available wind torque? Best Regards, Muskan.

Hi! Engineering a functional metal windmill pump requires precise sizing of the rotor sweep to generate enough torque to overcome your 1-meter static head. I will design the complete mechanical system, translating wind power through a reliable direct crank or gearbox to ensure a steady 10-50 L/h flow rate. To calculate the exact blade pitch and mechanical stroke length, what average wind speed should we optimize the baseline performance sheet for? Rather than just drawing virtual shapes, my expertise lies in SolidWorks mechanical design combined with practical industrial fabrication. I will provide fully toleranced 2D manufacturing drawings, the 3D CAD files, a precise BOM (including bearings and seals), and the requested assembly animation. Thanks to my hands-on experience overseeing shop-floor production, every metal component will be engineered strictly for real-world machinability, structural durability, and smooth operation.

The prompt for a metal windmill water pump prototype presents a clear fork in drivetrain design: direct crank arm versus a gearbox. I would go with a direct crank arm, so that it minimises complexity and potential failure points, and also keeps the number of moving parts down for better reliability given the moderate complexity you're aiming for. I'll start by modelling the rotor blades and central shaft in Solidworks, then design the crank arm mechanism that connects to a simple piston pump, all in metal. I'll base the 10-50 L/h capacity on a steady breeze of 5-8 m/s, so that it's achievable with a direct drive. The size will be around 50cm tall, so it's suitable for a desktop or garden demo. What I would assume until you tell me otherwise is that the shallow well has a lift of around 1-2 meters. One thing that is underspecified is the exact diameter of the well opening. Preferred Freelancer here, 5.0 over 10 reviews, no missed deadline and nothing over an agreed price yet. I will have a basic Solidworks model of the rotor and crank mechanism ready in the first day or two.
