Gluing up the top

Now the inner side of the back beam is planded flush and the middle blocks are fitted for gluing.
Here we go with the first one:

The bottom piece is the beam (with the butterflies in it).
Above is the end-middle-block and on top is a waste wood as a supplement.

Here the two endblocks are already glued on, the two middleblocks are clamped.
On the left side one can see the other beam with freshly glued wedges filling the cracks between the butterflies.
