Got started on the stove.
Air intake is a slide that closes all holes when slammed to the left. It runs in two mini angle iron channels, and can be pulled completely out to clear away rust/debris. These stoves are tight enough that you can stop the fire even when full of fuel and rocking, just by closing the intake.
Handle is a chipping hammer cut off.
Door handle pivot. Two big nuts drilled out to allow smaller bolt to turn free in them. Install bolt/nut adjust tightness and weld nut on.
Stove gets a ramp for the latch to catch on. I try to adjust everything so the ramp will compensate for wear over the years. Important to have the ramp upside down, so the handle locks on the down stroke from the outside (it's more intuitive, and gravity holds it closed).
I despise cheap sloppy stoves with outside latches.
The short piece welded to the door is to stop the handle from rotating all the way around. When this is omitted, people let the handle fall straight down, then can't seem to figure out how to close the door correctly.
