Work you can turn around and look at

Three of these parts are below as live models. Drag them, switch to wireframe to see the construction, or to blueprint to read them the way a drawing does.

Case notes

Six jobs, start to finish

Client names are withheld, but the engineering is exactly as delivered.

Rotating equipment

8-bolt flanged shaft housing

Problem

A rotating drive shaft needed a sealed housing that bolted to an existing 8-hole pattern nobody wanted to redrill.

What we did

Bore, O-ring groove and boss height were sized around the customer bolt circle and shaft tolerance, then checked for wall thickness and seal squeeze.

Bolt circle
Ø150 × 8 holes
Bore
Ø45 H7
Material
EN 1.0503 / C45
  • 3D model (STEP)
  • Dimensioned drawing with GD&T
  • Printed fit-check prototype
Valves and actuation

ISO 5211 actuator bracket

Problem

An actuator had to sit on an F05 valve top with enough clearance for the drive adapter and no fouling on the stem.

What we did

A machined bracket set the stack height, with the mounting face and drive coupling kept concentric within a tolerance the shop could actually hold.

Interface
ISO 5211 F05
Stack height
86 mm
Concentricity
Ø0.15 A
  • 3D model (STEP)
  • Production drawing
  • Material recommendation: 304 / 316 SS
Power transmission

Spur gear and hub drive

Problem

A discontinued gear had to be replaced with the same centre distance and ratio, from a worn sample.

What we did

Module and tooth count were recovered by measurement, the profile rebuilt parametrically, and the keyway and hub matched to the existing shaft.

Module
3 mm
Teeth
24
Bore / keyway
Ø25 H7 / 8 × 4
  • Parametric model
  • Gear data table on drawing
  • Cutting drawing for the gear shop
Sheet metal

IP54 control enclosure

Problem

A panel builder needed a folded enclosure sized around an existing plate layout, with a door that stayed square.

What we did

A 2 mm folded body developed with correct bend allowance, gasket channel and hinge reinforcement, released as nesting-ready flat patterns.

Sheet
2.0 mm CRCA
Bends
18
Finish
Powder coat RAL 7035
  • Flat patterns (DXF)
  • Weldment and folding drawings
  • Hardware and gasket schedule
Material handling

Conveyor idler frame

Problem

Field-welded frames were arriving with inconsistent roller angles, so belts tracked off centre.

What we did

The frame was re-drawn as a jig-friendly weldment with located slots and one datum face, so the trough angle is set by the part, not the welder.

Belt width
800 mm
Trough angle
35°
Sections
ISMC 100 / 75
  • Weldment model and BOM
  • Fabrication drawings with weld symbols
  • Cut list
Process equipment

Pump skid drawing pack

Problem

A skid was being built from supplier PDFs with no single arrangement drawing to work from.

What we did

Pump, motor, baseframe and piping were modelled as one assembly, giving a general arrangement, spool drawings and a bolt-by-bolt BOM.

Footprint
2400 × 1100 mm
Line size
DN80 / DN50
Standard
ASME B16.5
  • GA drawing
  • Pipe spool drawings
  • Foundation bolt layout
