The first job was to accommodate the spring break mechanism so I needed to drill the box accordingly and fit a bearing plate and pin, to allow the musical movement to play.
These were made from an odd end of brazing wire and a brass scrap. The movement was then fitted into place with machine screws and the winding key accommodated on the bittom of the box. Endless tinkering with the set up then ensued to ensure proper working.
The movement now plays when the lid is opened and is silenced when shut. The box is wound from underneath. The next jobs are to fit a decorative cover to the movement and fit feet to raise the box off of the floor.
