Yesterday and today were spent making adjustments to the window   frame to ensure the fittings for the fixed light and droplight fit properly.  Holes were drilled for the side pieces and all the screws ordered.  New pads for the screws for these fittings were made out of Delrin, initial trial show these will work well.  The last thing I did today was cut an 8″ x 7/8″ strip of Delrin to form the rounded corner.
