Trying to make this maintenance work easier

I bought the two piece box set years ago from Harbor freight because I wanted the top for my enclosed trailer. I had to take the lid off so it fits under the top counter boxes but I can still use the top. The bottom was a catch all but my new valve grinder fits perfectly on top of it. My old valve grinder had a nice wooden cabinet but John being John I can’t get rid of that valve grinder. I may put a collet setup on it if I ever get time just in case.
