Hi deliberately showing the PCB on cardboard so that he could try every fun with electronics.
PCB on laminate requires additional tools and chemistry, If, electronics pulls find appropriate how to do it.

The adjustment to the PCB, forgot one bridge

the second image, assistance for mounting

Rusty What I would say is use the designs that I have done on pages 3 and 4 that show colour printed board and wiring lines, The version that I have done in the v12 engine electronics.zip file makes use of wiring on both sides of the PCB, Henryk's is good, one thing that I would do just as a extra protective measure is to use insulated wire. A good source for this wire would be if you can get one's hands on telephone cable wire that has lots of thin wire strands and cut and fit the wires to the correct length.
Then use clear wood paint to seal it from any water or other damage.

Retunga, pages 3 and 4 where. I was actually thinking the same thing about the wire. Got plenty of it between telephone cords and Network cords :D

22 gauge should fine for the thin wiring lines on the PCB's I would use say 10 gauge for the thicker lines on the power PCB especially round the input part of the circuit and around the power transistor.

Hi , retunga not overdo it the path width of 1mm carries current to 3A , the whole system gets a barely 70mA, quiet I can do track width of 0.25mm
