I just remembered that I had a detailed drawing of what I did. A picture is worth a thousand words. See attached.
This was a test fixture for a small PC board. The main part of the fixture was a board on the bottom, with short pins that contacted the back of the board under test. The pogo pins are part of a separate assembly that goes over the top and serves the dual purpose of pushing the UUT down onto the lower pins and contacting a couple connectors on the top of the UUT. Not shown are pan-head screws that hold the upper-most board to the male-female standoffs.
