You may or may not have noticed the recent ‘miniature cooking’ trend that has been making the rounds on the web as of late. Folks have been taking on the challenge of cooking complicated meals that aren’t larger than your thumbnail not because they want to eat it – but because it is a fun engineering challenge. Scale just about anything down enough and you’ll run into really interesting problems. That is what the team at Discommon Goods learned when they manufactured this keychain sized replica of a 2000 Ferrari Formula 1 piston rod assembly.
After getting their hands on a real piston rod salvaged from a blown engine, the crew at Discommon scanned it, and got to the long and hard work of miniaturizing a working replica. In order to get the cast silver piston to move freely on the carbon connecting rod, the machinists had to use a special laser welding technology and forge the carbon rod around a silver bearing. The result of all this hard work is something that true lovers of Ferraris and engineering (to risk sounding redundant) will treasure. Hard work doesn’t come cheap, however. This American made keychain retails for $450. [Purchase]
