To cut the openings for glass panels in solid-core doors, the author first plunge-cuts with a track saw.
Corners are finished up the corners with a jigsaw.
The result is a clean cutout with square corners.
Split jambs that fit snugly in the opening hold the glass in place.
The author pins the panel molding to the jambs.
He temporarily tacks the assembly to one side of the door.
The assembly is used for reference as he flips the door over and glues and pins the remaining frame to the door. The tacked frame will be removed and finish-coated along with the rest of the door before the glass is installed.
