How do I connect a con-rod to a rod without blocking the rod's axis? · Hardware · basis: Design values; Ø3 dowel (ISO 8734) stub pin, 623 con-rod eyes from the con-rod kit on this site

Notes

A small block on the rod end with a Ø3 dowel pressed 4.5 mm into its side: the con-rod's 623 runs on the 7.5 mm that stand out, beside the block, so the rod's axis stays free.
The tube yoke has a Ø3.4 passage above its Ø5 socket: in the beta the Ø3 displacer rod runs up through the power piston's tube rod and out of the top of this yoke to its own rod yoke.
Both hold their rod with an M3 grub.
