I managed to put my folding mechanism together and pinned it up on the back wall for storage.
Mark Hastings machined the mechanism for me on his CNC and then offered to put a 10mm drill
through the centre of the pins so I could use a tool to remove them easily should I ever need to once
the boat is finished. Interestingly that hole through the pins reduced the weight of all the pins by 1kg.

Small savings add up.
