Holding Small Armatures for Winding
Procure a strip of sheet metal, 6 in. long, 1 in. wide, or as wide as the armature core is long, and 3/32 in. thick. Bend this into a U-shape, as shown, and file each end similar to the barb on a fishhook. Drill two holes for a bolt to pass through the sheet-metal ends. Fasten a screw or bolt in the center of the bend, to be used for gripping in a chuck or polishing head. Core segments can be quickly wound with this device.—Contributed by Geo. B.

Armature Cores are Easily Revolved to Fill the Core Openings with Insulated Wire
