Props for the DIY ingenuity, but for that price, I would just go and buy a Harbor Freight 5 gallon portable air tank, like http://www.harborfreight.com/air-tools/air-compressors/5-gal-portable-air-tank-69716.html. About the same price and no cucumber jamming. Also has a fair bit more capacity, so you might be able to do multiple tires with one fill.
