24/07/2009 Achievements

Electric Go Kart

  • Calculated that chain is "420" (ie 6.35 width between plates, 12.7mm pitch)
  • Looked hard for, and found, sprocket for the electric motor - namely: http://tncscooters.com/partsdb.php?type=ES
  • It is called a "D-Bore" sprocket.
  • Decided axle (17mm steel) ... because it is too much trouble to cut "keyways" in expensive axles ... which cost $150 new anyway ... and even if purchased second hand, have to use expensive hubs and carriers for everything (crazy !).
  • Thoroughly welded is going to be plenty strong, and reliable.
  • Also - get to use little sprocket (14 teeth).
  • Worked out how to weld round wheel bracket to rear axle.
  • Spoke to Poppy about this, and got his approval to do this.
