Issue # 166 November 2004

The challenge for this project is to design a floor register that is reasonably easy to make, but still retains basic blacksmithing techniques. The process begins with the fabrication of a special tool that winds the hurricane shaped register fill elements into shape. Then they are shaped on a series of fixtures and forms that make sure they are all uniformly finished. The damper is a two piece design that drops into guides at each end of the register; a removable crank raises and lowers it to adjust the air flow.

Three cranks are covered in issue 166 starting with a hex crank designed for use with the floor register. The other two (shown here) include a machine crank and a “two-speed” crank that provide both fast travel and extra leverage.
