You use the section you cut out. Pull off the masonite veneer and the edge
and you have a straight piece you can use in that "open hollow" Glue and
finish nails to hold it in place.

Thanks. I was thinking that may be what they do. I saved the cutoff pieces
in case that is the way to do it. I haven't tried separating the masonite
from the wood filler strips, but hopefully thta won't be too hard to do.
