Drill 4X6[1]
Aaron has a pretty intense looking drill, he writes – “High speed drill made from auto blower motor (10,000 RPM). No need to center punch. Works great on aluminum sheet. Better than any other drills I’ve tried.” [via] – Link.

On a related note, Kevin Kelly has a great new site called “Street Use” with a lot of “Made on Earth” & “Heirloom Technology” style posts filled with ways in which people modify and re-create technology – Link.
