Making the back

20200606
I started to thickness the back while waiting gluing other parts.
The back is a damn dense wood which is very hard to plane.
I think this process will take some time.

Now more planing and scraping time.
Thicknessing this wood is a pain in the ass.
It is very taxing on the tools too.

Next I close up the box with clamps to mark the position of the back braces.
I insert my arm into the box with a pencil to mark the position of the back braces.

Glue the back seam reinforcement made from spruce off cut.
The pieces are glued using the radius jig to give it a pre-curved shape
The other 2 back brace are also glued to the body rim.

Next I shaped the back seam reinforcement to a nice curve profile.
Also I check that the reinforcement is at the right place not interfering with the back brace and end block when the box is closed.

After using chisel and plane I also sand the back seam reinforcement
