Let’s build the windlass, starting with the ratchet gear. After studying a number of pictures of the Sultana’s windlass, I determined that the ratchet gear has 12 teeth. I created a 12 sided polygon and added one tooth.
Then I used the circular pattern function to copy the tooth for a total of 12 teeth.
An extrude operation created the final shape of the ratchet gear.
Adjacent to the ratchet gear, I created an octagon, then a second smaller octagon the correct distance away.
I used the loft function to create a shape between the two octagons, then mirrored that shape to the other side.
The holes were added and both rectangular and circular patterns were used to place the holes around the windlass.
And finally, the supports were modeled.
All of the windlass parts were 3D printed.
The windlass pawl and galley stack are connected. Here is a picture of the galley stack. For now, I have decided to omit the white cover on the galley stack.
This is the galley stack 3D model.
And this is the 3D printed part. I used some burnt sienna paint to indicate rusting. (There is no rust in my photo of the galley stack, but it is present on other photos I have found.)
The windlass and galley stack glued on to my Sultana.
