We ordered a replacement crank from a gentleman who goes by the handle "trailertrasher" and parts out old trailers in the California Desert.
The finished window and the valance we made to cover up the clear panes on the top. We wanted to replace all of the privacy glass with clear, but did not want to spend the $30 at this time, as it can be done at any point in the future.
Next we started playing with the door. The door itself seems to have some internal rot, has ugly metal on the interior and is difficult to get apart, so we just removed the door frame and installed it.
We wanted to get the sill in place as kids are damaging the small bit of skin at the bottom of the door, getting in and out of their playhouse.
