For certain reasons I am interested in constructing low power circuits using wood instead of PCB/Protoboard as a surface upon which to place and join components. Although many might find this silly, I still want these circuits to be high quality, rugged, efficient, and just as functional as a circuit not laid on top of wood.
A simple method to achieve this in my mind would be to place screws as junction points, then solder the component wires to these. The solder connection should be sufficient to hold light components. Heavier components I plan to investigate fixing to the board with fasteners.
My question is this: Will any commonly available screws (zinc, stainless steel, ...) have sufficient conductivity to produce an efficient circuit. If so would a certain common material/conductor be preferable? I assume size will effect the resistance/conductivity? Should I measure the resistance of the screws to get a good experimental idea of their resistance/conductivity? Is there a certain range that I should be looking for?
If commonly available screws are not sufficient, my next idea was to look into hammering solder header pins to the wood, however I am worried they could come loose from the wood over time.
