How to Measure Wheel with Hand and Tools
Wetin casino technician dey check, with which tools, and how often. How normal maintenance dey help keep wheel fair.
Level, rotor balance, how deep and wide di pockets be, fret height and how dem hold, how di ball track don wear, and di condition of di deflectorsequipmentDeflectorOne of di metal tins for di apron wey dey scatter di ball as e dey fall. Dem also dey call am: canoe, diamond, pin.Read di whole tin →. Dem dey check dem on schedule with spirit level, dial gauges, balance rig and logbook. Dem dey rotate rotor heads between bowls so dat no defect go stay with one table.
Why Dem Dey Measure
Wheel na machine and machines dey wear. Wheel wey no level by small part of one degree dey drop di ballequipmentBallDi small ball wey dem dey throw for di track against di rotor. Modern balls na ivorine or Teflon, 18–21 mm.Read di whole tin → more often from di high side; fretequipmentFretDi metal wey divide two pockets for di wheel.Read di whole tin → wey don loose dey change di bounce beside am; ball trackequipmentBall trackDi groove for di rim wey di ball dey run inside before e slow down and fall.
