A professional who operates battery of compressor machines and drying ovens to press and dry cardboard-fiber and wood-flour slurry to form filler wads for shotgun shells. Respnsibilities include:

• Turns valves to fill compressor jackets with slurry and to heat drying ovens.
• Starts feed tank agitator, wad compressors, and conveyors.
• Observes molded wads emerging from compressor punches to detect concave tops indicating fouled punch tip.
• Unbolts punch tube and cleans accumulated slurry from tip, using compressed air or water.
• Replaces bent or broken punches, tubes, knock-off fingers, and transfer plates, using handtools.
• Weighs specified number of dried wads from each batch of slurry on grain scale, and computes quantity of water needed to produce wads of specified weight.
• Measures thickness of wads, using dial gauge, and adjusts spacing between top and bottom punches to change wad thickness, using micrometers, feeler gauges, and precision gauge blocks.
• Washes accumulation of slurry from machine.
• May operate and adjust battery of stationary pneumatic compressors that press slurry into holed wads for further compressing into base wads and be designated Base-Wad Operator-Adjuster (ordnance).
