Australia and Britain are two countries separated by half a planet and a common language. According to the excellent instructions with this kit, down under what we call a "solebar", they call a "sill". There's also the Americanism of numbering drill bits, so we make a 0.7mm or #70 hole for the cross wire.
Apart from this, chassis construction is pretty conventional to anyone familiar with a Parkside or Cambrian kit. Bearings are provided but moulded in derelin rather than turned from brass. They pop straight in the axleboxes though so no difference.
Interesting that there are only 4 brake shoes and that they act on the outside of the wheels as opposed to the inside as you find in Britain.
