[Ben Ardwin] was asked by a friend to help fix an old motor. It needed a new set of brushes. They’re just thin pieces of copper that mount on the motor housing and contact the commutator. The metal is so thin he thought he’d try fabricating replacements by dissolving copper stock. This is not copper [...]

Above you can see the broken knob on the left, and what it is supposed to look like on the right (taken from [Francisco's] own vehicle for reference). We’ve encountered split shafts on plastic knobs before and decided it [...]

The Off-Grid Container House:   Project to make an off-grid container house.  [...]

Satisfy your need to view some quality machining by looking through this Stirling engine worklog. We’ve seen these engines used a few other times in creating electricity from solar energy, powering a car, and even built from aluminum cans. [David Morrow] built this rendition to push the limits of his machining skills. We’d say he [...]

[Alex] bought a hang on tank filter for his aquarium. Unfortunately it was made for a different water level than he was using and didn’t have the ability to adjust that he needed. Add to that the non-standard pipe sizing which compounded the problem by making it difficult to extend the intake and output tubes. [...]
