What I do — and
what you get.
Every service below ends with the same thing: files your fabricator, moulder or machine shop can build from without guessing. Here's how each one works, with real examples of the deliverables.
Industrial machine design
Custom machinery designed end-to-end: conveyors, material-handling systems, automation cells, agitators, hoppers and special-purpose machines. I take a process requirement — "move X from A to B at Y per hour" — and turn it into a machine your local fabricator can quote and build.
- Concept layouts with 2–3 design options and trade-offs explained
- Full 3D assembly in SolidWorks — weldments, purchased parts, hardware
- Drive, bearing and actuator selection with calculation notes
- Safety guarding to machine-safety standards
- Complete fabrication drawing package with BOM
Example: general-arrangement drawing from a conveyor project — every fabrication package includes GA, sub-assembly and part-level drawings.
Product design & DFM
Products designed around the process that will make them — not fixed afterwards. Whether it's injection moulding, sheet metal, CNC machining or 3D printing, manufacturing constraints are baked in from the first sketch, so tooling quotes come back sane and parts come out of the mould working.
- Industrial design concepts and ergonomics studies
- Detailed CAD with draft, wall-thickness and snap-fit engineering
- DFM review reports — for your design or mine
- Tolerance analysis on critical fits and assemblies
- Tooling-ready files: STEP, parasolid, 2D critical-dimension drawings
Example: section detail from an injection-moulded enclosure — snap-fit undercuts, draft angles and rib rules all resolved before tooling.
Technical drafting
Manufacturing drawings your shop reads once and builds right. Whether you have finished CAD that needs a drawing package, legacy 2D that needs remodelling, or hand sketches that need formalising — I produce ISO/ASME-compliant drawings with GD&T that actually means something to the machinist.
- Part and assembly drawings to ISO 128 / ASME Y14.5
- GD&T applied where function demands it — not decoration
- Weldment drawings with weld symbols and cut lists
- Sheet metal flat patterns, bend tables and laser-ready DXFs
- 2D-to-3D conversion and legacy drawing cleanup
Example: machined plate with positional tolerance to datums — GD&T applied so the shop measures what actually matters.
