enlarged knot hole opening in old window sash
I am working on replacing the sash cords in some of my old windows. On several of the sashes, the knot hole and lower part of the channel in the sash is enlarged such that prior knots slipped out, dropping the weights (the cords were not broken). I used a thicker rope (the last was about 30% thinner) and also secured with a nail driven at a downward angle. But in the back of my mind I'm thinking the knot will fall out of the hole. Has anyone else run across this? I'm thinking of installing weatherstripping but I really don't want to have to undo it if the knots slip.
