Can anyone please point to any on-line sources of information on maintaining and repairing Georgian-style sliding sash windows. There doesn't seem to be any reference to these in the DIY FAQ of Wiki.
My holiday flat - which is part of a converted Georgian building - has this type of window. Some of the counter-weights tend to jam in their chambers, so I need to dismantle them to see what's going on. Although I know more or less how they work, some diagrams of various cross-sections
- showing how the components separate - would be very useful. A couple of centuries of paint make it very difficult to see where they split - so I need to know where to insert the blade of my MultiMaster!
