Just finished the Midship Capstan.

The capstan consisted of a timber mounted vertically through a vessel’s structure which was free to rotate. Levers, known as bars, were inserted through holes at the top of the timber and used to turn the capstan. A rope wrapped several turns around the drum was thus hauled upon. A rudimentary ratchet was provided to hold the tension. 

I found that I may have needed a bit more room on the deck but that’s ok.
