Unscrew the sash stoppers (a thin vertical strip of wood that supports the sash) and remove any paint-encrusted hardware. Reverse the sash to reveal the weight. It is a massive iron or lead cylinder, which is tucked away in a cavity, and supported by a cord. To keep the sash from falling into the void pierce it with an hammer and then sacrifice the weight.
