About

Home technician who documents tear-downs and quick fixes with standard tools.

Core Beliefs

Machines last when owners can service them safely and often.

Background

A neighbor's machine wheezed and leaked after three years. We opened it on a kitchen table—standard screwdriver, new o-rings, no drama. Thirty minutes later, pressure recovered and drips vanished. That afternoon convinced me: clear parts diagrams and serviceable layouts aren't luxuries; they're how espresso stays affordable and dependable.

Perspective

I prefer designs with accessible fasteners, clear routing, and available spares.
