Models assembly tips

  • If you hold the
    board with its front side directed to you, it is better to remove the
    parts by pulling them. In this case, if a burr is pulled together with a
    part, it will make a pit in the board, not in the part. The best
    solution is to incise the hangers with a knife;
  • If you have
    difficulties in inserting a toothpick in the assembled gearwheel, rub
    the toothpick with a candle;
  • You may also
    lubricate all the projecting axes of the gearwheels before installing
    them on the frame. In this case the friction during rotation will be
  • However, do not
    lubricate the parts of pendulum connection with a candle two
    projecting sticks in the tractor or timer. In this case the pendulum
    will not swing but skid;
  • Try to remove
    big burrs on the gearwheels, if any. The motion of some models is very
    delicate, and they may hinder it;
  • If any
    gearwheel creaks or squeaks, lubricate it with a regular candle,
    paraffin or wax. If the plywood edge is too resinous and some teeth tend
    to seize, which happens quite rarely, lubricate the gearwheel in the
    same manner;
