I made a couple of powder measure quick disconnects for my dillon measures.
Started with 3/8 aluminum I dug out of my stuff. This piece measured 1.43x1.93.
Drilled 3/4" dia and counterbored 7/8 × .17 deep.

Cut in half, dress with a file.

Spot the holes with a drill bit, center punch, then drilled .190.

Found a spring in my stuff and cut it in half to .6 long. Added (2) 1.5 x 10-24 socket head cap screws.

Works great. I though I would add a screw as a little grab tab, but being 1.9" wide it sticks out enough to grab from both sides easily.
