The majority of these pegs are large on one side, and smaller on the other. It is essential to remove first the smaller diameter sides. Later sashes used glue instead of pins. They can be cut by using a knife or mallets.

After the sash has been removed then you can take out the sash stop and gain access to the weight pocket. Usually, this is done through a hole near the bottom of each jamb.

They are typically wedged into or nailed but can be prised free and it's worth your time here. If the sash remains in place, pull the mortise and tenon joints free using a hammer or screwdriver and then remove each wood peg. The sash should be able move freely now, but it may require some lubrication to feel less stiff.
