Peachtober day 9: Rope

[image description: a black and white watercolor and pen illustration of several rope-and-pulleys, like those found on a sailboat, stretched across the page, with a view of the sea in the background. a pale human figure is falling from above, suspended as if cut cleanly in half by the uppermost rope, which has a large fraying knot tied exactly where the figure's core/stomach would be. /end i.d.]

Description

Cottage scene of family, a man, woman, three children and baby, seated round a table in the corner of the room, writing a letter. On the right, the man, dressed in brown breeches, white shirt, and red waistcoat and neck tie, sits with a received letter in one hand, a map of South Australia on the table before him. The children are gathered closely together, intent on writing a letter on the table, the boy on the left holding the pen. The woman sits slightly apart from the group, her head turned slightly towards them, with a baby on her lap and a dog at her feet. She is wearing a green dress with a red apron, and a white bonnet. The baby attempts to pull a sock onto its right foot, copying its mother. Behind her, to the left, is a large black kitchen range, with the glow of a fire, and various toys and ornaments lining the mantlepiece. A bird sits in a cage attached to the wall next to a window on the right, pots of geraniums and cups lining the window sill. Sheets hang from a pulley system across the ceiling.

Here's my latest progress on the winch in place pulley setup. I opted for 10lb test 0.12mm diameter PE fishing line (orange color) as the output that will interface into the first pair of downgearing pulleys of my archimedes pulley downgearing system. This turn in place pulley achieves 2.77:1 downgearing ratio now. The motor shaft reels in 32 inches of string that is 6lb test 0.08mm pe fishing line (black) and after the downgearing pulley, the final amount of orange fishing line reeled in is 11.55". That's a much more manageable amount of runout for the archimedes pulley system to deal with to keep it more compact. The archimedes pulley downgearing system will add an additional 16:1 downgearing to this which brings me to a total of 44:1 downgearing. The motor itself pulls at .5lb pulling force so after 44x that increases to 22lb of pulling power. After mechanical disadvantage is factored in, I estimate the finger can curl 5.5lb ideally which is about the same strength as my finger. So that's perfect and VERY strong IMO.
