Yesterday, the Hazard Factory, an industrial arts studio, hosted the 3rd annual Seattle Power Tool Race & Derby. Participants construct a dragster powered by at most two “power tools” to race head to head down a 60 foot plywood channel. The rules are fairly loose and creativity is encouraged just as much as performance. For an example build, [spacematters] posted his machine using a circular saw and inline skate wheels. A Flickr photo pool of the day’s shenanigans is coming together and you can see some of the registered entries on the Hazard Factory’s site.
