Machined Pipsqueak Engine
Built a functional Pipsqueak engine from stock metal. I took the project through CAD design,
redesign for manufacturing, and hands-on machining of specified components along with my team.
Core engineering challenge
Creating a reproducible physical engine from stock metal, with specifications that allowed for simple assembly and use.
Build contributions
CAD to manufacturing
Modeled engine components in SOLIDWORKS and created renders, exploded and assembly views, a BOM, manufacturing drawings, and process sheets. Iterated the design to improve fabrication and assembly.
Sand-cast flywheel
3D printed a pattern and used it to sand-cast the flywheel.
Lathe operations
I turned the piston head and other rounded parts to fit critical dimensions.
Mill operations
Faced components, reamed holes, and machined mounting features and mechanical interfaces.

Assembly fit-up
Built from CAD and manufacturing documentation into a functional physical model with sand-casting, lathe, mill, and fit-up work.
