After the window casting fits the opening, use a small machin-
ist's square to make sure that it is plumb (vertical).
If there is more than one window on that side of the building,
place a straight edge along the bottom of the window castings
to make sure that they are all level to each other [7]. Unless the
castings all fit tightly, I clamp the straight edge to the building
wall while spot gluing them at the top of each window to make
sure that none of the castings move out of alignment. I then
remove the straight-edge and finish bonding them in place.
While doing the photos for this article, I checked how long it
took to complete a window opening from start to finish using
a nibbler. Without rushing, it took just over a minute to “drill”
and carve an opening for the nibbler head, and the same

casting.
