One of the best things I got from my brother when he moved out of his huge house into a small apartment was his compressor. It’s amazing how useful air is.
So most bike tires these days have presta valves, which are not nearly so easy to deal with as schraeder valves like those on cars. There are adapters that sort of convert presta to schraeder, but they’re kind of a cumbersome, and I wanted something more convenient. Surfing around, I found a tool that does it commercially available for $50.
But since I already have a blower tool, and I’m terminally cheap, I decided to try build one for less.
Voila:
And just screwing around a little, I turned it into an Instructable.
