I manage a motorcycle plant in Pakistan and I’m ready to bring in a hands-on expert who can tighten up our quality control for the scooter line. Day to day you will walk the production floor, run mechanical and visual checks, and fine-tune the machinery settings that most affect final fit and finish. Your eye for consistent welds, paint depth, torque specs, and component tolerances should already be second nature from similar two-wheel projects. I’m particularly interested in candidates who can spot recurring defects early, trace them to a root cause, and work side-by-side with technicians to correct tooling or process parameters on the spot. Familiarity with the standard gauges, calipers, and test rigs used in scooter manufacturing will help you slot in quickly. If you have e...

My Samsung front-loader sits in the laundry room and its door seal finally gave out. I already have the genuine replacement door gasket and have removed the torn seal, and fitted the new one. However, I need the metal rings re-attached, and run a quick test cycle to confirm there are no leaks or vibration issues. Please bring the basic tools usually required for this type of job and any seal-safe lubricant you prefer. The washing machine is easily accessible with power and water shut-offs right beside it. If you’ve worked on Samsung or similar front-load washers before and can complete the swap efficiently, let’s set up a time that works for you.

I’m developing a drone for an engineering project and need a skilled CAD specialist to turn my reference images and hand-drawn sketches into a fully detailed mechanical design. Your task is to model every component, assemble the parts so tolerances and clearances make sense, and create a short motion animation that shows the drone’s range of movement and an exploded view for presentation. You’ll receive the sketches and photos as soon as we start; they outline the overall frame, motor mounts, landing gear, and gimbal concept. From there, I’d like you to: • Build precise 3D geometry of each mechanical part • Produce a clean, constraint-driven assembly that fits together without interference • Generate an MP4 (or similar) animation that rotates th...

Produce a clear hydraulic schematic—ISO symbols preferred—showing ...

I need a complete CAD package for a standing-seam roll-forming machine. The 3D assembly must show every shaft, roller, gearbox, frame member and other moving component so that motion, clearances and maintenance access can be verified. Once the model is approved, translate it into 2D production drawings with fully dimensioned views ready for fabrication, all drafted to ISO standards for mechanical design and safety. I do not yet have fixed overall dimensions, so you will guide me on a practical industrial footprint that balances throughput with floor space. Material choices, standard part call-outs and bearing specifications should be included where relevant. Native SolidWorks files are welcome, and I will also need STEP and DWG exports. Deliverables: • Detailed 3D assembly of the co...

I’m developing a new food-processing machine and need an experienced mechanical product designer who can take it from concept sketches to a complete, production-ready CAD package. The core of the assignment is full mechanical design: modelling all components and assemblies, laying out the drive system, and making sure the entire line meets food-industry hygiene and safety requirements. You’ll translate my functional notes into detailed 3D geometry, refine the mechanism for manufacturability, and generate the fabrication drawings we can hand straight to the shop. I work in SolidWorks myself, so native files in that format would be ideal, but I’m open to Inventor or STEP if that suits your workflow better. Good practice in tolerancing, material selection and sealed-shaft d...

I’m putting together a simple proof-of-concept: an XY plotter that uses stepper motors and a motor-driven cream / syringe head to write one predefined word on plain paper in four different sizes. The word and the sizes will be hard-coded for now; no live UI or font selection is needed. I just want to see smooth, accurate motion, clean cream extrusion, and clearly legible lettering in an “Elegant” style. Here’s what I need from you: • Mechanical design and parts list for the XY frame, rails, carriage, and syringe mount, all sized for an A4 sheet of paper. • Electronics schematic and firmware (Arduino + GRBL, or any open-source control stack you prefer) that drives two XY stepper motors plus a third actuator for the syringe. • G-code or equivalen...
