Here are a couple of better pictures of my powder scale set up.
It sits on a fold down shelf mounted to the cabinet of my reloading bench.
When I’m done reloading, the scale is protected by a small cover of my design that my wife sewed up for me, and then is set back into the cabinet so I can close up the shelf and have room to work on my bench.


Note the shorter chain location on the left side to provide better access to the tray.
This shows more detail about the shotgun primer jar.


I cut down a plastic jar and taped it back together to get a reasonable volume in a low profile container.
The lower picture also shows how I attached the wing nuts for the tool key blocks.
