The majority of them are large on one side and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes that were made later in the century used glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised area loose with mallets.

It is essential to be patient as they're often wedged or nailed in place. If the sash remains in place, pry out the mortise and tenon joints using the help of a hammer and pin or screwdriver, then unhook the wood pegs that are on the components.
