Rest the window on the temporary 2x4 and screw it to the wall. Center the window on the opening before driving the screws.
Cut the side pieces.
Set the side pieces in place over the top of the header and mark the angled cuts.
Finish the curved trim piece by first cutting the angles on each end, and then sawing the curves with a jigsaw and sanding them smooth. Use the marking jig to lay out the curved brace, too.
Cut the sill piece and assemble the windows with pocket screws.
Using a router with a 3/8-in. rabbet bit, rout a 3/8-in.-deep recess on the back of the window to receive the 1/4-in. Plexiglas acrylic sheet.
Set the window frame, recessed side down, over a piece of acrylic sheet and trace the shape with a permanent marker.
Cut the curve with a fine-tooth jigsaw blade and the straight sections with a fine-tooth blade in a table saw or circular saw.
Prime and paint the window and let it dry.
Then apply a thin bead of clear silicone in the recess and embed the acrylic sheet in it. Secure the acrylic sheet with glazing points. Let it set up overnight.
We cut the grid pieces from 3/4-in. x 1/2-in. parting stop and glued them to the acrylic with clear silicone caulk.
A temporary support makes it simple to install the window. Level a 2x4 and screw it to the wall 2 in. below the window opening. Then rest the window on the 2x4 and center it in the opening before driving screws to secure it. Use caulk to fill the gaps left by the grooved siding.
