The door dart was modified to suit the new door. The square and thread needed to be continued down so it would clamp up the door. A simple collet was made to be able to hold it in the lathe and rotary table chuck to do the milling.
To set the square up in the rotary table I firstly aligned the dart with the flats on the hex and installed it in the chuck. Then a steel rule was put across the chuck jaws and leveled up off the mill table. Because the graduations on the table didn't line up with 0, I set up a magnetic base and home-made indicator to work off.
The backing plate behind the firedoor needed to be replaced as the construction was rough, and I could incorporate a bracket to mount the tea can tray above the door.
Doors jam in the tracks and need to be replaced. Next job!
Happy steaming!
Nigel
