Continuing with window frame construction today, I welded the rear flange to the top section of the second frame today.  I also constructed a frame jig that will allow me to easily align and weld the top and sides together.


Started work on the second frame, folded the top front flange (two pieces) and the small half-inch inner flange (also two pieces).  Welded the two front flange sections together and started to square the edge in the vice.


Completed fitting the Delrin blocks to the window frame today, then gave it a coat of undercoat ready for fitting up.    However I think this will need to wait now until I find the right rubber for the top of the frame.
