Tire Valve Stem Cap Tool

[mklotz]

For those who think that their tool may be "too simple" to post, please don't let that stop you.

Everyone has lost a tire valve stem cap, whether it fell inside a hubcap, or rolled away from your first bicycle and was hard to spot against an asphalt driveway. Even a child can build this tool.

Let me echo Jon's thoughts: even the simplest ideas can inspire others' ingenuity.

As an example, a simple variant of this tool is to use it as a nut starter. Substitute a nut for the stem cap and you have a way of starting a nut on a bolt buried deep inside a piece of machinery, electronics, whatever. Once started, the tool easily pulls free from the nut.

Another variant... Fitted with the right size tubing and a push rod, such a device can be used to insert BBs into a BB gun clip or small bearings into a ball screw.
