Elliot, How will you cut in the new windows without disturbing the filler pieces? I would think it be easier to cut out the new windows in a new strip of aluminum and then insert the new strip into one larger section of space occupied by the larger windows. I have never done this type of modification but it seems to me that it would be an easier approach. Just a thought. Neat project and I look forward to the end product. SKOL, Dave
P.S. Thanks for the early Amtrak Builder ride. I wish that they were still using some of the old equipment such as the dome cars. Had a nice overnight ride on the Canadian from Jasper to Vancouver a few years ago and spent the whole night in the dome car enjoying the moon lit view.
Just had another thought: Cut out the space between the first large window and the last large window and then insert filler spacers between to create the size windows you want to use. Just another thought.
