Looking good! Are you going to sit it in a brick box, so it is off the floor, and not tippy, or are you going to put some of that square tubing on the bottom, to make it stable? I would also, make a spring, handle on the wrench, so you can open it with the bare hands. My wood stove here in the house has that, on the door latch, and the small damper, but not on the main damper, as it is below, and on the side. You can also put some of the muffler pipe, at an angle on the sides, and weld flat plates to the top of those, and the stove, and you could have your pot of water on the stove top, for steaming, and humidifying, and the side plates for cooking, or for more water, or glue pot, etc. Or use the stove top for cooking, and the side plates for steaming, and so forth. Ahh, venison stew slowly cooking on the wood stove while you scrape a nice piece of Osage, maybe even some dough baking in a dutch oven on top also......
Oh boy, in your man cave, with the smell of wood, the sound of a fire crackling, venison stew, and fresh baked bread, sigh...... Do you have a clean out trap, or tray? Nice build along. Thanks. Now you will have to make a bow for the welder.
