It flowed nicely once I tinned the tip of my soldering iron. It has been a while since I have done any soldering. Also, for the opposite end I changed my method of mechanical attachment. First, I was going for intermingling the wires and twisting. What worked better was twisting the strands first and then twisting the two wires together and then soldering.I found the key to getting your solder to play nice is flux. Put a little soldering flux on the connection before you start to heat and the solder will flow really nicely.

Flux would have been a nice touch but I forgot to get it.
