Second Try 'cause of wrong wood :-(

Because Paulownia is horrible to cut with chisels (strange ... I did it somewhen, but maybe just with saws) I had to buy pine.
I choose 28 mm thick pine ... so the tool-chest will have a lifespan of a few hundret years :-)

5 parts Quark, 1 part lime ... waterresistant Glue :-)
