The sketched version is my third version of this concept. This is how my second version looks like:

Difference between this version and the third version will be the tube at the side, which is now moved to the back of the ytong nest.
The pieces of plastic to make the ytong expandable are attached with gypsum.

I am still experimenting with this setup. During the weekend i will make the third version. If this concept proofs that it works, then i will make more nests of the same layout.
Any suggestions, advice or ideas?
