The Dreams of an Inventor in 1420
- pontifier 9y agoThat last image with the spheres seems like one of the most straightforward... The sphere is in 2 halves, the long U shaped piece with the barbs ties them together. The clasp at the top can enter the U shaped piece before it is inserted into the sphere. The tuning fork thing is the key. insert it through the 2 holes in the bottom and the barbs on the U shaped piece are bent back so the U can be removed.
