Roy, nice looking project.
If I may, definitely follow Don’s advice about the draft channel on the door. It will help keep the door flat. Otherwise it’s going to warp on you. BTDT.
Maybe even a small angle run around the perimeter of the door to give it more resistance to warping.
Please post pics of the stove in action when you’re done.
I did take use Don's advice and have welded a channel to the back of the door for draft. The hole is cut in the door, flap installed over it with a keeper, and a channel around the inside perimeter for the door seal. Was working on hinges when I quit last night. Going hunting this morning but I'll get some photos when I can.
