Thanks David. It is really enjoyable process despite of repetitions.
Assembled upper springs bed.
You need to glue a ring from two pieces: inner and outer.
So i bent them and glued together asymmetrically, which gave a little tab to close the ring.
Also spent several evenings to cut bogie frame parts
At this stage i used three (!) different thickness carboards: 0.7, 1, 1.5 mm
