Two new tools were set in the New Britain-Gridley lathe, pictured above, to adapt it for the cutting of twenty-millimeter shell booster parts. The new parts are an eccentric spindle, which may be seen attached to a driving rod in the center of the machine, and a thread rolling attachment. In peacetime, the machine was used to turn out spur gears, worm wheels and commentator rings in steel and brass
