About

I kept seeing the same problems. Designs optimised for CAD instead of manufacture. FEA run without realistic load cases. Products that passed a review but failed in the field. Engineers who'd never held a spanner advising manufacturers on what was possible.

Carchrie Engineering exists to catch those problems early. I started it in 2019 after 12 years in industry — across production vehicle development, bicycle hardware, and consumer products — because I'd seen what happens when structural and manufacturing reality is treated as someone else's problem.

My background spans the full cycle — as the mechanic who fixed it, the designer who created it, the manufacturer who had to build it, and the customer who relied on it. That's not a marketing line — it's the reason we catch things other reviewers miss.

01
Mechanic
Field failure reality. Understanding how hardware breaks in use, what the warning signs are, and how to design against them from the start.
02
Designer
Engineering judgement. 16+ years of design decisions, structural analysis, and the discipline to validate rather than assume.
03
Manufacturer
Production constraints. Knowing what can and can't be made at cost — and what needs to change before tooling is committed.
04
Customer
End-use perspective. Understanding how hardware is actually loaded, abused, and experienced — not just how it performs in simulation.
16+
Years hardware experience

Mechanical systems, test jigs, fixtures, and load-bearing structures.

Client feedback

What clients say

GGoogle review

"Carchrie Engineering was recommended to me by a business colleague. I had a clear idea of what I needed but James added a lot of value with his collaborative ideas. He was open to meeting my tight deadline, plus he found me someone to build the product. Six stars."

Matthew D, Hydric Desalination
Custom Mould Design

"I want to keep him all to myself. He's been an exceptional partner — understands the domain and communicates it in a way I can follow, which has been instrumental in moving the design forward. Reluctantly, I highly recommend."

Franc G, FG Designs
Dining Table FEA

"As usual, delivered on time to the high quality needed. Always easy and stress free to work with. Professional, helpful, and his services will continue to be used as and when needed."

Peter B, Private Client
Cam Handle Design
