Freelance Mechanical Design Engineer helping manufacturers turn concepts into production-ready CAD and fabrication drawings.
Whether you have a rough hand sketch or a full project scope, I deliver practical CAD models and production-ready drawings for real workshop use.
No polished drawing required to start. A clear photo and key dimensions is often enough.
I'm a part-time freelance mechanical design engineer specialising in CAD modelling, fabrication drawings, and reverse engineering for manufacturing and engineering projects. I work with companies and individuals who need reliable design support to turn ideas, sketches, or existing components into accurate, production-ready CAD models.
I have experience creating SolidWorks and AutoCAD designs used in real manufacturing environments, producing clear technical drawings and models for fabrication, machining, and prototyping. My focus is always on delivering designs that are practical, manufacturable, and easy for workshops to form.
If you have a part, drawing, or idea you'd like help developing, feel free to get in touch to discuss your project.
Turn rough paper sketches, marked-up prints, or whiteboard notes into clean technical drawings.
Clear production-ready drawings with dimensions, tolerances, notes, and revision details.
Workshop-friendly drawing packs and documentation prepared for fabrication and machining teams.
Accurate CAD models built from existing parts, legacy drawings, or physical measurements.
Manufacturing-ready profiles and flat patterns delivered in agreed cutting and exchange formats.
Design support for test builds, including 3D printing and practical feedback before production.
Built for both quick sketch conversions and full CAD development projects.
Sketches, photos, old drawings, or a full design brief. Include any key dimensions and constraints.
I confirm scope, delivery format, and lead time so you know exactly what is being delivered.
Get accurate, workshop-ready outputs in agreed formats such as PDF, DXF, and STEP.
Client requested a custom 8-bolt flanged housing to seal a rotating drive shaft using an o-ring.
Using customers bolting and drive shaft parameters, o-ring and housing sizes created and designed suitable for a rotating drive shaft
Client needed a custom throttle cable holder for an RV14 aircraft, designed to fit within tight space constraints and withstand vibration, bending forces, and temperature variations
Designed a custom throttle cable holder suitable to fit both throttle cable sizes with full range of motion.
Client required a bracket design to suit F04 mounting bracket size to ISO 5211 with suitable clearance to provide adequate contact with their drive adapter
Designed a custom ISO 5211 mounting bracket with appropriate height and width. Recommended material 304SS or 316SS
Starting prices are shown below. Final cost depends on complexity, tolerances, revisions, and required delivery format.
Simple sketch-to-drawing jobs often start from the same drawing baseline, subject to part complexity and available dimensions.
Minimum project charge: 1 hour. Exchange formats include PDF, STEP, and DXF as agreed.
