First job this week was to fit the new interior panel to the cab door and check that the the slam lock fitted.  Next, I gave the slam lock a final coat of paint.  I have been using Simoniz black engine enamel aerosols for small black parts, it appears to be very good.   I also stripped as much of the remaining paint as I could from the emrgency door casting that encases the handle for opening.   I next turned my attention to the cab door sliding window, which I removed by heating the stubborn screws with a paint stripping gun.  The frame needs some repair in places, due to rot, so I needed to remove the glass, which I achieved by finding two hidden screws in the bottom rail at each corner.   I finished stripping the emergency door casting and gave it two coats of primer then started the complex job of repairing the cab door window frame by first making a strip of steel with a beaded edge to match the inner flange of the window.   I then cut out the first section of rot and welded the newly-made piece in place.
