These measurements can be taken to an hardware or home centers store to get a piece cut of stock glass to the right size. You can also cut the glass by yourself if you possess the right tools.

After putting in the new pane, run a small bead of caulking along the edge to ensure it is weatherproof. Then, you can install a glazier's pointing on the frame's opposite side to hold the pane in place. The points shouldn't be too tight that they cause friction between the sash and frame but they shouldn't be too loose.

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

Then, you can use the point of your chisel, or the back end of the putty knife to tap in the glazier's points as illustrated in Figure 11. After you're done, the points should be in line with the top edge of the pane and the raised shoulders of the points should be below the lip of the rabbet groove.

Apply a small amount of glazing compound on the edges of the new glass and into the rabbet grooves to seal and protect them. Let it dry and cure completely.

Install the new window sash once the glazing compound has dried. The first step is to coat the wood with a thick layer of linseed. This will prevent the new putty from drying out or cracking when it absorbs moisture. Use a brush to apply this coat, or the tip of the blade.

After the old glazing points and putty have been removed prepare a bed for the new pane. Roll a piece of glazing compound between your hands, and form it to be around 1/2-inch thick.
