As soon as the original window sashes were rebuilt (see part 1) they were primed on all sides for ultimate protection against the weather. The upper sashes were to receive a custom glass window, so the frames went to the artist for installation. After the glass was installed, yet before returning to the house, the sashes were painted. With the cycle of rebirth nearly complete, the last thing on the restoration list was to install the sashes back into the window opening.
Whenever rebuilding old double hung windows with in-wall counterweights, it's a good idea to replace the sash cords while the windows are apart (see attached slide show). It's a relatively easy thing to do, and guarantees many more years of service. Also, make sure to examine the pulleys to ensure they're in good shape. There was only one pulley on this project that needed attention. The bent wheel was easily repaired with a careful twist on the pliers. Once the cord is attached to both the window sash and counterweight, the windows are replaced and put back into service. Although these old windows don't have the insulating qualities of a new unit, they are the genuine article, remaining true to the period of the house. With careful fitting and attention to detail, however, they should have minimal drafting and provide many more years of carefree service.
