Quoted from jls667:I have become very good at cleaning stepper units and putting them back together. Some were really gummed up with old lubricants.
I assume that I should be using powder on the sliding surface during play. Is there supposed to be some catch box underneath to catch the powder as it falls through the holes? In my case the powder just falls on the floor.
Yes, These united shuffle bowlers have a sheet metal tray about 3 feet long and as wide as the lane to catch powder.
