02 DEFINE THE POSSIBLE
An idea becomes a model you can question, refine and develop. The same process works for any product.
ILLUSTRATIVE STUDY / ENTRANCE CONTROL
03 RESOLVE THE DETAIL
Fit, movement, access and assembly. The details that make a design practical to build, use and maintain.

04 THE DESIGN STUDIO
SolidWorks, material decisions and physical prototypes. A design process that travels well between industries.

05 WHAT I DO
Extra capacity for your engineering team, or a fresh pair of eyes on a difficult product. I work across components, mechanisms and complete products. Materials, tolerances, tooling and assembly belong in the same conversation—from the first model to the release pack.
Whether it’s one component or a complete assembly, I work through the interfaces, materials and manufacturing decisions, as well as the model.
Start with a need, a rough concept or a product that needs to improve. I connect the function, materials and process, then work through the iterations that make the idea ready for manufacture.
ALSO BEYOND THE CADOne more thing I build for engineering teams.
Macros, scripts and small tools that take repetitive work off your plate. If you keep doing the same steps in CAD, spreadsheets or file handling, we can look at a simpler way. Built around the way you already work, then tested on your real job. If the tool needs a screen or a web page, I build that too.
MATERIALS & PROCESSES
The right shape is only part of the answer. I design with the material, manufacturing route, assembly and working environment in mind.

01 / FORM & FOLD
Bend allowances, fold sequences, access and assembly. Enclosures, brackets and practical fabricated structures.

02 / DATUM & TOLERANCE
Functional datums, sensible tolerances and tool reach. Design decisions informed by real CNC and CAD/CAM experience.

03 / SHELL & STRUCTURE
Wall sections, ribs, draft and clear interfaces. Housings, covers and ergonomic parts that fit the product and the process.

04 / CAST & FINISH
Robust metal parts, practical tooling and the detail needed for finishing, machining and assembly.
05 / FORM & TRIM
Draft, radii, tooling and trim profiles. Lightweight shells, covers and panels with a clear route from CAD to manufacture.

06 / PROVE & REFINE
Printed proof parts, jigs, fixtures and test rigs. Build enough to answer the question, then improve the design.
THE ENGINEER BEHIND THE BOX
I'm Ronnie Adshead, a contract mechanical and product design engineer based in East Sussex. I work remotely, hybrid or on site, using SolidWorks to take ideas from concept through to production-ready designs.
I currently work in the defence sector. My wider experience spans aerospace, industrial systems, entrance control and commercial products, with hands-on ownership of designs from the first prototype to production.
Earlier work in 3- and 5-axis CNC and CAD/CAM gives me a practical understanding of tooling, setups and the factory floor. I bring that knowledge into design decisions, supported by SolidWorks PDM, simulation and clear manufacturing documentation.
A PRACTICAL WAY FORWARD
A conversation about what needs to work, what’s in the way and where help will make a difference.
Models, prototypes or working screens. Something concrete to test and improve together.
Usable output, explained decisions and a handover that helps you carry the work forward.
EVERY GOOD PROJECT STARTS SOMEWHERE
A new idea. A stuck project. Something that could work better. A rough outline is enough to start.
