I used to turn out hundreds of bushings a night when I worked at Viking Pump. Automatic screw machines. Most of the orders were 10,000 part orders. Brass bushings up to about 4" diameter.
Viking pumped countless tons of asphalt oil for me trouble free for many years :lol:Not like it was never abused :rolleyes: The mornings when the plant heater system quit over night and the rosebud came out to warm it up a little. Starting the pump with a plugged return line :eek:. Power failures with both lines full. :rofl:
