Take these measurements to an hardware store or home center and have a piece of stock glass cut to size. Alternately, you can cut the glass yourself if have the tools you need.

After putting in the new glass Apply some caulking on the edges. This will make the glass weatherproof. Then, place a glazier's tip on the frame's opposite side to secure the pane into the right place.

Before applying the putty on the surface, knead thoroughly until it is smooth and free from lumps. Then, roll it into pencil-size strips. Apply the first strip to the corner of the frame. Work from one corner to another to ensure it's even and smooth.

If you do sand your wood, make sure to protect it with painter's tack to avoid accidental damage.

Place the new pane into the frame and push firmly using your hands. Then, use the tip of your chisel or the back of the putty knife to make a tap on the glazier's points as shown in Figure 11. The glazier's points should sit in line with the top edge of your pane, and the shoulders raised should be just beneath that lip.

Apply a thin layer glazing compound on the rabbet grooves as well as the edges of the new glass. This will seal and protect the edges. Let it dry and cure fully.

After the old points of glazing and putty are removed, make a bed for the new pane. Roll a rope made of glazing compound between your fingers, and make it about 1/2 inch thick.
