Colonel00 I wish I saw some of these before I started building, Some great ideas you tossed around. I found this picture today because I was thinking of adding an umbrella mount to my cart and this came up in a Google search.
Here is how I stand right now. I do have material to add an aluminum shelf above the cutting board. I might do a smoke on the stand to get a feel of how I move around it and where i need hooks and mounts.
A big thing I want is an aluminum foil dispenser It would make sense to have the foil pull across the cutting board, But that would mean mounting the roll under the board... Not sure how to work that out yet.
