I first cut a piece of 1/4" inch Masonite about a quarter inch
smaller than the opening of the window.
Next I attached furring strips to the inside of the window well.
I set them back about 3/8" to accommodate the thickness of the Masonite, magnetic strip
and the steel. I then painted the strips blue to blend in with the rest of backdrop.
I went down to Menards and got a couple of rolls of 1/2" flexible strip magnet
and three pieces of 1/8" X 1/2" X 4' weldable steel. I cut the steel and the magnetic strip
to size. The magnetic strip comes with a sticky back but the adhesive
on the tape will not work on porous surfaces so
I used contact cement to attach the magnets to the furring strips.
I then glued the steel to the back of the Masonite.
Here's what the window looked like before I put the trim in place.
For the trim I used moulding that's used to connect 1/8" think panels together.
I cut the back of the moulding off with a utility knife and the fastened the trim to Masonite.
I cut the angles using a miter box. Here is the result after the trim has been glued in
place and painted.
Now It's time for me to wield a flaming paintbrush and liberate the artist in me...ROTFL.
