2 things to keep in mind for your bench. Wood absorbs water, or oil. that is a no-no for keeping sand in condition , especially part time. Copy an existing design in shape and function, unless you REALLY need to be diferent. My bench was jsut about the size of a chest freezer. I saw one made from caniblizeed fridge parts, all metal. It is where the idea of my blaster cabinet came from, a dead fridge. Also wood can burn, steel will not. The cabinet must be able to seal up fairly tight, or you get cats making deposits, or mice making tunnels, and dust making things, well dusty or dry. Cover the sand with plastic sheet, and close the doors and forget it. A good top will make a fair work surface for double duty when not casting, like most of the time. Shape the front slightly like a bin, and keep the sand in the box, shovel it when needed, out on the floor, and stomp, walk, flip it to combine the oils and fines. The heavy plastic sheet or tarp makes this easy to contain the sand, and then cover it later. A mull is nice, but expensive to buy. A common storage bin can hold all the brushes and slicks, tools and tubes, for molding, and slip into the cabinet to be ready when you are. The flasks can be wood or metal, but sized to the parts you make. You dont need a 2x3 foot 10 inch deep flask for 60 lbs of sand for a coupler knuckle, or boxcar end frame. Keep it simple, and flexible use. Space is precious little in my world, and expensive.
