In Part One I had just crammed the knotted end of the sash cord into the hole in the side of the sash. Now the sash can go back into its jamb:
After placing the sash back in the jamb, I feed the two newly-attached replacement sash cords over the top of the pulleys on each side and let them hang.
In a comment in Part One, Seth reminded me about securing the knot. I tip the sash out a bit, put a finish nail through it and bend it over. That’ll hold it!
Next I tie the weights onto the sash cord. I use both a knot and baling wire (rather than the interesting and original but awkward sash cord fastener) to further secure them.
No more need for a stick in the window! Now that the sash is properly counter-balanced it will stay in whatever position it is placed. Only 19 more windows to go! Fortunately, the other rooms will retain their plaster; this is the only one to be sheetrocked.
