Window Work

I have replaced most of the windows in the loco with clear plastic from Home Depot. The windows are made with a C channel frame. The top comes off so that the glass can be inserted. they fit in a larger steel C channel tracks at the top and bottom of the window. The bottom of the windows rusted out. I wanted to find some C channel to replace the bottom frame of the windows. That C channel is no longer available. Hank suggested 1/4 inch square tubing. Hank milled out one side making 1/4 inch C channel. I welded the channel to the bottom of the widow frames. The top track is removed by breaking off all the old screws. The new windows are placed in the bottom track, the top track is placed on top of the windows and the assembly is pushed back in the frame.
