The only stranded - solid connection that I trust is solder.

I tried soldering on some scraps. I dipped the wires into flux and then
tried to solder them. The solder adhered to the stranded wire as well as
could be, but it skated right off the solid.

I have never soldered anything but stranded before, but don't understand why
the solid is different.

Any advice here?

You probably need a hotter soldering iron. I bet you've got a fairly
low-powered unit. Try something around 100W or bigger.

Also, don't use plumbing solder, which is lead-free. Get some 50/50 or 60/40
leaded solder and try that.
