Window reno project - hit a wall
The window sashes in the rear of my house have no pulley systems for holding them open. I call them guillotine windows. I am/was planning to install pulleys and weights, and finally started the project by removing one casing from one window, expecting to see space behind the casing. Instead, there is a solid board there.
Any ideas for what I can do now? Is there any chance that if I drill a hole through that board I will discover an open pocket? I would be willing to switch to spring balances, but even for that, I need some space behind the side jam to install it.
I have eight windows like this. This one that I started with happens to be the only one on a load bearing wall. I don't know whether that matters or not.
