An odd beginning to the week by going off plan to complete the lighting switch-box cover.  This was prompted by a need to clear workshop space.  I still need to fit a clasp to the hinged cover over the fuses.  I then cut the channel to size for the cab window fixed pane, in preparation for welding the angle that retains the anti-rattle/draught excluder fabric, the angle having arrived today.  The next day was unexpectedly sunny so I got on with preparing the wheels for primer.  I sprayed them with red oxide the following day and and was satisfied with the result,  having given them two coats, despite the freezing cold weather.   I wasn’t feeling great the next day, so just touched up with a brush any areas I’d missed on the wheels.  I next turned my attention to the cab window and assembled the bit of vertical frame required for the fixed pane, this involved welding angle to the channel to hold the strip of material for the draught/anti-rattle seal.  This went well except for catching the enf of the channel with the tip of the mig, burning a bit away.  Having trimmed the overlapping angle, it was apparent that this would hardly show so I left it.  Last job was to spray the assembly with red oxide primer, before the cold  (-2C)   drove me indoors.
