Soldering together the parts and further assembling the pieces

Although I had purchased some preassembled electronics, I still needed to solder them to the pickups.
Also, it turned out that the grounding wire that connected the two pots, had been placed on the side of the pots, and this made it impossible to fit everything into the routed cavity.
This is the circuit diagram:

I removed the grounding wire between the pots and started putting together new ground wires for the pots as well as for the shielding of the routed cavities and the pickguard, bridge and control board.

I then connected the bridge pickup and the neck pickup to the pots, switch and ground, with the neck pickup requiring me to add a new ground wire as I had chosen a 4-way switch for my Tele.

I then assembled the bridge, making sure that one of the ground wires would connect with the bridge from underneath.

When I then tried to assemble the control board, it turned out that the routed cavity was still not wide enough for my pots to fit in completely.

I took my chisels again and made the cavity a bit wider in those areas that the pots would go, making sure to keep them narrow enough so that they would still be covered by the control board.

I then painted these parts with shielding paint again, two layers...

Once dry, I tried to assemble all of it again, and this time things fit together nicely:

I screwed on the knobs, then I selected a switch cab. The plastic ones didn't look nice, so I took a nice metal one, but again, it was all too shiny, so I had to use some sand paper, wax and heat to make it look a bit more aged.
