So I AM going to use SMD's + Resistors as, for me, that is the only logical thing to do. In order of achieving that, I need to solder 4 SMD's along two lengths of 30 gauge wire. Each SMD will/should end up being central above the area between the pits when installed. Note I did say "should be".
So let the work begin. I started out with a length of double sided tape attached to a length of styrene:
Next, I lined up where the SMD's needed to be located and lightly pressed each onto the tape:
That held the SMD's in place while I soldered the 30 gauge wire to each:
The same process for the soldering of the other wire will be used obviously.
Each length of wire is long enough to go across the shop, down one side and a further 6" beneath the bench work where they will attach to 26 gauge "bus wire" that will run back to a Toggle Switch. Well, that's the theory anyway.
Only three of these assemblies with done and each will be attached to the bottom of the three trusses running across the shop. The wires will be "pressed" into the side of the trusses which, hopefully, will add to their concealment. The wires will then be painted the same color as the truss - gunmetal grey metallic.
The ends of the wires will run nicely down the sides of the verticle beams and through the bottom of the Shop floor via small holes yet to be drilled.
