I've made some progress, but still need to make a shelf for over the bench and some shelves for under the bench. I put a lock on the cabinet because it seemed like a good idea, at least I made an effort to keep things safely out of curious hands (no kids in our house, it's just because).

The cabinet will be for powder and primer, as well as accessories I have room for.

I picked up an LED light from Lowes, seemed like a handy thing:

The most ambitious part of the project is the dust cover, I may upgrade this to a larger model

I got impatient, er, I realized the most prudent thing to do was put this setup through the paces and see how it does, so I spent time I could have been building, and started working up some loads. Other than having powder leak from the auto-drum it went well. I haven't tried it again, but I opened it up, cleaned with solvent and added graphite under the cone. Those pesky holidays and relatives are going to keep me from getting more done until after New Years, but such is life.
With the spent primer tube on the right, the stool stores neatly on the left. I'm thinking shelves will need to go on the right unless they're shallow. The low storage I'm thinking will be for bullets and cases, and case cleaning gear.
