182. Dan buoy assembly. Two have been tapered on the lathe.


Dan buoys Dan buoys were fl oats that were tossed overboard to mark cleared lanes when minesweeping. T ey were retained when the minesweeping gear was removed. I made mine from round toothpicks and concentric plastic rods. (Figure 182) T e cone shaped ends were formed on the lathe, using the slowest speed and gentle pressure on the cutter. (Figure 183) Aſt er cleanup and painting, the buoys were lashed to their brackets that were previously built into the railings on the engine room casing. (Figure 184)


Smoke fl oats Corvettes typically carried six of


drill. (Figure 185) Aſt er detailing and making the mounting platforms (Figures 186 and 187) they were fi xed to the ship. (Figure 188)


Short-wave radar antenna


In 1942 Canadian corvettes received a National Research Council-designed radar


operating on these devices


mounted on top of the depth charge rails. Photographs show Chicoutimi’s atop the reload rails. T ey could be ignited at their stowed location or dumped overboard, where they would fl oat as long as smoke was generated. I made mine from 7/16- inch tube capped at one end, drilling the holes using a template made from 1/2-inch tube and a 1/16-inch


the 1.5-meter band called SW1C, which used a large Yagi antenna at the mast head. Ineff ective as a U-boat locator, it was updated with a new dipole antenna array and performed well as an air warning set. Now designated SW2C, it was retained when the centimetric radar was installed. I made my antenna from 0.010-inch rod and copper wire, based on photographs of Sackville’s, and installed it into its masthead bracket. (Figures 189 and 190)


Ensign and jack staff


Photographs show Chicoutimi fl ying the White Ensign on the jack staff at the stern. I used an Aeronaut fl agstaff modifi ed with a cleat and bracket
