Sets up and operates multispindle routing machine to cut sink openings in sandstone countertops and tabletops and to drill holes in synthetic composition board: Reads blueprints to determine location and size of sink openings or holes to be cut. Installs specified router bit in 45- or 90-degree angle spindle chuck, using chuck key. Positions sandstone slab or composition board on machine bed and secures workpiece to bed, using C-clamps. Determines distance from edge of workpiece to opening and distance between holes, and pulls levers, turns handwheel, and presses buttons to position bridge and spindle and to start and lower router bit to drill holes in composition board or route out sink opening. Observes ammeter to determine cutting resistance and lifts lever to reduce speed of drill or movement of bridge or spindle. Turns dial to set automatic control that stops and raises router when specified depth in board has been reached. Removes clamps and pushes workpiece from machine bed. Examines and measures slabs and pegboards to determine adherence to specifications and sands edges of sink opening, using sandpaper. Maintains production records.
