Mechanical Engineering & Design

From Scribble to Steel.

We turn conversations into products.

A Complete Engineering Service

Every project starts with a conversation and stays that way.

Mechanical Design

From rough concept to detailed design — 3D modelling, analysis, and everything it takes to turn an idea into something buildable.

Fabrication Drawings

Production-ready drawings your fabricator can actually work from. Full parts lists, tolerances, weld details, and manufacturing notes — done properly.

FEA & Stress Analysis

We find the weak points on screen so you don't find them in the field. Finite element analysis to validate designs before anything gets built.

Failure Analysis

Something broke and you need to know why. We investigate component and system failures, find the root cause, and give you a clear path forward.

Engineering Certification

Compliance sign-off to Australian standards — lifting equipment, structural assessments, and engineered documentation for equipment that needs to be safe and legal.

VSB6 Compliance

Engineering sign-off and compliance plates for modified vehicles. We handle the technical side so your modifications are road-legal and properly documented.

ATF Approval

We operate as an Approved Test Facility — bringing the credibility and rigour of formal testing and approval to your components and assemblies.

Project Management

One point of contact across the whole job. We keep things moving from scope to delivery without you having to chase anyone.

Engineering Systems

Part numbering, drawing management, drafting best practice. We build the systems that keep your engineering department running the way it should.

There's no shortcut to getting it right. We've never looked for one.
