Mechanical Design Jobs

I need a complete AutoCAD project developed entirely from the ground up. I do not have any existing blueprints, sketches, or partial files to build on, so every line and layer will start fresh in the DWG. At this stage I’m still refining the final scope—whether the end result is a set of architectural plans, mechanical components, or detailed technical drawings will depend on the discussion we have about feasibility, timeline, and best practices. What I do know is that accuracy, clean layering, and clear annotations are critical, and I’ll expect the native AutoCAD file along with a PDF plot when we finish. Once we agree on the direction, I’ll provide dimensions, reference images, or functional requirements so you can translate them into a coherent model or dra...

I am developing a new automatic gearbox specifically for a motorcycle platform and need a complete concept-to-prototype package. The priorities are clear: the unit must squeeze every kilometre out of a litre of fuel while still delivering snappy, high-performance shifts that suit spirited riding. Scope of work I already have the engine characteristics and mounting envelope; what I need from you is the full transmission architecture: gear train selection, clutch strategy, shift logic and lubrication layout. Packaging within typical motorcycle width constraints is essential, and the final design should accommodate standard production materials and processes so that moving to tooling is straightforward. Key technical expectations • Optimised gear ratios and control strategy that ba...

I have a working prototype that now needs a proper mechanical casing so it can move from the bench to real-world use. The enclosure will be 3D-printed in PLA on a standard FDM printer, so the model must respect the usual wall-thickness and overhang limits while still looking clean and professional. Core requirements • The design is strictly a mechanical casing (no electronics layout inside). • Integrate mounting holes for securing the unit to a frame. • Add ventilation slots that balance airflow and strength. • A combination of snap-fit and screw assembly will be designed, to aid with secure installations. I’ll supply rough dimensions, photos of the current rig, and the clearances I already measured; you translate that into a production-ready CAD model. ...

My Trumatic 500 (Finpower punch) is down because the punch mechanism has developed a mechanical misalignment. The tool head is no longer striking squarely, so parts are coming out with burrs and the turret jams after a few hits. I need an experienced service technician or mechanical engineer who has already worked on Trumatic or comparable CNC turret punch presses to: • diagnose the source of the misalignment within the punch mechanism • realign or replace the affected components so the tool head returns to factory tolerance • run test punches in multiple stations, proving consistent, burr-free results and smooth turret rotation You will have full access to the machine, manuals, and my maintenance logs. Bring any specialised alignment gauges or calibration sof...
