I was just moving some machines around and broke the handle on the sliding cover mechanism on the ball return hopper. You push this handle to the left to empty the balls into a tray at the bottom. The sliding cover allows the balls to go thru a round hole to the tray below. It is yellow. I took the four screws out and removed the spring and tried to glue the handle back on, but no luck. Does anyone have a spare that would work ? Does Arby have parts ? Frank A
