Seems like I am always waiting for something to finish - GG to cure, rain, cold, Great Stuff to cure, paint / mix / urethane to dry, and so on.
Slows everything down, doesn't it ?
Anyway, got the test fit done for the window inset and it fits well, so repaired all the larger divots and router oopsies with Great Stuff now I gotta wait for that to dry/cure before routing the bulkhead dado, fair the street-side wall and apply the canvas.
Window won't get screwed in place until walls are up and canvas ready to be applied on exterior.
