Removing sliding wood windows….
Here’s a tip for removing wooden windows (horizontal slide). The windows had frame channels on the bottom that rests on wooden rails (in the middle), while the top had trims on the outside to keep them aligned properly. Needless to say the fit was tight and would not allow for a “lift and tilt” removal. I decided to cut the rail in half diagonally. Using a flat bar I lifted both rail and window off the frame. Prior to reinstallation, I used a cheap candle wax (white) to coat the rails and reversed the process. Hope this helps.
