Gluing the pallet box to the soundboard

The pallet box frame is glued to the underside of the soundboard (i.e. the bar frame, bars and table), with leather covering the bars and channels behind the pallet box.  Originally the open channels would have been covered with re-used parchment manuscript, or more likely, the Coppel 8ft upperboard and slider would have been attached to the back of the pallet box.
