Mechanical & electrical engineers · Leeds
Engineering that works on site.
CAD, reliability and project support for industrial sites across the UK. We model the part, prove it with a prototype, and make it in our own workshop.

What we do
From a problem on site to a part that fits.
One team that understands both the drawing and the equipment it goes on, so the design is made with fitting and maintenance in mind.
Prototyping & parts
Printed prototypes for fit and assembly checks, then parts made in-house. Materials including igus options where suitable.
- 3D printing
- Plasma cutting
- Short-run parts
Reliability engineering
Practical help with recurring equipment problems, component replacement and engineering improvements.
- Failure investigation
- Replacement components
- Design improvements
Engineering projects
Mechanical and electrical experience to support industrial projects, modifications and work on site.
- Plant modifications
- Installation support
- Site work, UK-wide
Selected work
Real problems. Considered engineering.
Three recent jobs, each shown from the model to the finished part. Select any image to see it full size.
Reverse engineering
From a fragment to a replacement bush.
Only a damaged fragment of the bronze bushing was left. We modelled the part in CAD, printed a prototype to check fit against the housing, and prepared drawings for the replacement.
- Start
- Damaged fragment
- Scope
- CAD · prototype · drawings
- Output
- Replacement bush & housing
Site engineering
Silo filter installation.
The filter, base plate, angle-iron frame and weather cover were modelled as a full assembly before going to site, so the mounting could be checked before anyone went up the silo.
- Scope
- CAD assembly · site install
- Parts
- Base plate · frame · flange · body · cover
Mechanical design
Segmented mill plates.
The plates were designed in CAD as segments, so each piece can be handled through the mill access and fitted in place around the shaft.
- Scope
- Segmented plate design · CAD
- Output
- Plates fitted in the mill
How a job runs
Check the idea. Refine the part.
Printing a prototype first means problems with fit show up on the bench, not during a shutdown.
01
Understand
See the equipment, the failure and what the part has to do.
02
Model
Build the component and its surroundings in CAD.
03
Prototype
Print it and check fit and assembly against the real thing.
04
Make
Issue drawings and manufacture, in-house or through trusted suppliers.
40P Engineering Ltd
Yorkshire roots. Nationwide support.
Based in Leeds, we travel across the UK to support industrial customers. The team combines hands-on site experience with HNC qualifications in mechanical and electrical engineering.
With 3D printing and plasma cutting in-house, design and making happen in the same place, which keeps turnaround short.
