10. Assembly stage I: Installing the assembly elements on the
circuit board
a) Soldering on the brass shafts
Soldering on the brass shafts for the transmission and the wheel support should be your first soldering step. As this requires a lot more heat than
for the rest of the electronics, it may happen that the circuit board gets very hot and other components may be damaged as a result when
soldering them in later on.

Exercise utmost care when soldering!
If the shafts are soldered in crookedly, the later driving behaviour suffers extremely!
Prior to soldering, you should clean the shafts with fine sandpaper, which makes it a lot easier to solder the material.
You can fix the shaft into place with a small clothespin, for example. Afterwards, first solder the end of the shaft and then the soldering

spots on the left and right of the shaft.
This is how it is supposed to look like after soldering (procedure see below):
Fist you solder in the longer axes on the bottom of the drive unit (observe the illustration above and the labelling!). To do so, turn the circuit board
around and place the corresponding axis into the cut-out groove until it arrests. The axis must lie across the entire length!
around and place the corresponding axis into the cut-out groove until it arrests. The axis must lie across the entire length!
Then place some tin on the soldering tip and press the axis on the circuit board with it. As soon as the axis is hot, add solder to the resting points
to connect the axis with the circuit board. Once the axis is soldered on all the way around, press it down with a screwdriver and remove the
soldering iron. Soldering in the axis is most successful when increasing the soldering temperature (approx. 420°C) and using a broad tip
(approx. 3mm). Of course you have to lower the temperature again to approx. 360°C for the electronic components.

Once everything has cooled off, solder in the second axis on the bottom of the circuit board and then the two short axes on the top according to
the same principle.
the same principle.
Once the axes have completely cooled down, put on the transmission wheels. The teeth of the gearwheels must fit perfectly into each other and
be easy to rotate. If this is not the case, the axes are either soldered in crookedly and must be realigned, or there are solder residues on the axes
outside of the circuit board. These must be removed. You best clean these off with a fine file or sandpaper. If everything fits, the gearwheels are
set aside and the remaining components are placed in their future positions on the circuit board.
