Here’s a great how to on Instructables on making a pedal powered air compressor, Aaron writes – “replace the electric motor of an air compressor with modified bicycle drivetrain. pedal. keep pedalling…use the existing motor mount to install an axle with one fixed cog and a belt pulley. You’ll need bearings. try a 1/2″ axle with radial ball bearing cartridges. make the bearing housing out of a slotted tube that has a drilled out nut and a regular nut to allow a bolt to tighten the tube around the bearing….” Link.

I’ve got to disagree with you, these are not very good instructions. There aren’t any photos or illustrations of the steps required, nor is there enough description to make up for the lack of documentation. I commend Aaron for putting it out there, its a really cool idea, but it needs more to make it “great.”
