Step 6

              Solder cable
  • Pull the cable part with the plug through the half-axis and solder it. So that not all soldering points come to lie on each other, the cables are soldered in different lengths. The whole thing was insulated with heat shrink tubing.

Step 7

              Mount half axle
  • The half axle is mounted again. Wrong the first time, as can be seen in the picture :-). The marking must be in the right place again so that the flats of the half-axis match the other half.
