I needed a fixture to align a switch, a round printed
circuit board and a spring for soldering. The parts
all had to be coaxial and coplanar.

I made this over the weekend. It works beautifully.
How did I do it with just a manual lathe and mill?

Machine left side cavity, machine right side cavity, press or otherwise
fasten the two pieces to each other, then finally mill away the top and
sides of the assembly.
