1970s motorcycle CAD recreation
Reverse-engineered from reference and measurement
A set of 1970s motorcycle components rebuilt in CAD from reference and physical measurement, with no original drawings to work from.
View case studyMechanical scope
Alongside core mechanism design and structural enclosures, we support the detailed engineering decisions that ensure parts assemble cleanly, function reliably, and remain economical to build.
Motion and mechanisms
Linkages, hinges, linear motion guides, motor mounts, bearings, gear trains, and supporting structural frameworks.
Materials and finishes
Selecting metals, engineering polymers, and surface treatments to balance strength, thermal performance, corrosion resistance, aesthetics, and unit cost.
Fluidics and sealing
Fluid and pneumatic routing, custom seals, IP-rated enclosures, bonded assemblies, and subcompact component packaging.
Drawings and tolerances
Detail component drawings, tolerance stack-up analysis, sheet-metal development, and GD&T to ASME Y14.5 to control key features without inflating cost.
Electromechanical integration
Enclosures, mounting strategies, connector access, harness routing, sensor placement, and close ECAD–MCAD coordination.
Supplier & fab support
Manufacturing documentation and technical communication with machining, moulding, sheet-metal, and prototyping partners.
Design for manufacture
Every manufacturing process imposes distinct constraints on geometry, tooling, surface finish, and unit cost. We incorporate those constraints from the earliest CAD models, whether designing for CNC machining, sheet metal fabrication, additive manufacturing, or injection moulding. For moulded assemblies, this includes draft angles, wall uniformity, parting lines, boss geometry, and prototyping strategies to validate performance before committing to production tooling.
Scaling beyond a prototype demands rigorous attention to tolerance stack-ups, assembly sequence, jigs, fastener torque specs, and clear inspection criteria. We deliver production-ready drawing packages and assembly instructions so that parts built in volume match the performance of the prototype.
