Then, use a wood chisel, or putty knife, to take the remainder of the old putty around the frame and sash. Be careful not to scratch the window sash. Work slowly and carefully.

The points shouldn't be so tight that they create friction between the sash and the frame however they shouldn't be loose.

Before applying the putty on the surface, knead thoroughly until it becomes soft and free of lumps. Then you can roll it into pencil-sized strips. The first strip should be glued to the frame's corner. Work from corner to corner to ensure it's even and smooth.

Glazier's Points

The glazier's points are the small triangular pieces of metal that allow glass to be secured into the frame of a window without damaging or scratching the delicate surface.

Place the new pane into the frame and press it down with your hands. Make use of the point of the chisel or the edge of the putty blade to tap in the glazier's points, as shown in Figure 11. The glazier's point should be aligned with the top edge of your pane and the raised shoulders should be just below the lip.

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

After removal of the old pane clean the frame and wood. Scrape off any old paint, and sand the rabbet grooves that the glazing points were placed. These should be sanded down to bare wood so that you can paint them the same color as the rest of the frame. After the sanding process, apply a coat of flax oil to the wood's surface to help extend its lifespan.

Next, measure the dimensions of the window opening. You will need to measure the horizontal and vertical dimensions of the entire opening, as well as the thickness.
