Electronic – simple way to DIY a coaxial male connector

coaxdiypower

I have a 12V power supply that has a female coaxial plug like the one on the right in this image:

Male and female coaxial plugs

I rigged something up with tinfoil just to see if it would work, but it's not ideal at all. Basically, I have two stripped wires that need to connect to the inside and outside of the female plug, respectively. Does anyone know of a trick to do this (DIY) without finding a matching male part?

I have used soldered multithreaded copper wire for central connector (the pin) and stripped, unsoldered wire wound around and secured by electrical tape on the barrel. That is, before I can get a suitable connector. Even better is to strip off the plug and connect the wires. I'd rather do that that start building a connector. I could try a piece of bent metal sheet as the connector for the barrel. Hint: it doesn't need to be all around the barrel, just touch at some point along the barrel.
