Model No. 24001
not structurally checked.
The first S-joint, developed by Momentum Engineering with Architecture 00:/. It employs two bolted fins with S-joints between pieces. The S-joint itself is designed to maximise the quality of connection between the two pieces, but in fact in this configuration most of the stuctural work is done by the bolts. As a result, this version is very heavy on bolts, and can certainly be improved upon. Note that recommended bolt-set spacings are shown.
