If you decide to sand wood, protect it with painter’s tape to protect it from damage caused by accidental sanding.

Take measurements of the empty frame and note down precise measurements. Take these dimensions to an hardware store or home center, and have the new pane cut slightly smaller than the frame's opening. This will ensure a tight fit and will allow room for expansion and contraction.

Place the new pane into the frame and press it down with your hands. Utilize the point of the chisel or the edge of the putty blade to smudge the glaziers' points as illustrated in Figure 11.

Once you're ready to begin, begin by removing the old window by prying out the glazing points made of metal that are connected to it. These are basically small metal triangles that function as "nails" which hold the window in place in the wood frame. They are submerged beneath a bead or glazing putty that sets to form solid wedge that holds the wood frame firmly in position and hides the sharp edges.

After you have the old pane taken away Clean up the frame and wood. Scrape off any paint and sand down the rabbet grooves, where the glazing points used to be.
