This is my version of the "Capstan Hammer" of the Flying Dutchman (cf. https://www.youtube.com/watch?v=9gp73EZdObM)
if you want to see the mechanism in action visit https://imgur.com/a/g2uad because I cannot upload more than 0,1 MB :/
The most challenging part was to construct the inner part in such a way that it rotates along with it, but can also be lifted and falls down abruptly. In addition, the mechanism should be kept so small that it can be installed in a normally dimensioned ship.
Although the rotary movement of the hammer during lifting is not exactly the same speed as that of the capstan, I am still quite satisfied with the result.
