Can two (2) 14 gauge wires, twisted and soldered together, replace
one short length of 8 gauge wire??

Unfortunately, no. I am looking at the Belden catalog, technical
information section and it says that 14 AWG wire has a cross section of
4107 square mils and a resistance of 2.5 ohms per 1000 ft. This is half
and double the values for 11 gauge wire. This means two 14 AWG lines
equals only an 11 gauge run. It would take at least three and maybe four
runs of 14 gauge wire to replace one run of 8 gauge. wire. Of course a lot
depends on what is the important parameter. If voltage drop is important
then use four runs. If just not melting down is important then you can get
by with three if you separate them to inprove the cooling ability.
