	Mechanical engineering is not my thing, which is unfortunate because I enjoy making stuff that is used and should not fall apart. In my trail of destruction lie bendable garden tools, fallen shelves, and bicycle trailers tipping their loads in the rain and at night. I once tried to find myself an evening continuing ed. class on engineering, but to my surprise this isn't how it works—nobody wants their city's bridge designed by a punter who picked up their math on odd nights out and a couple of video explainers.

	The ceiling lights became a subproject: old halogen bulbs burn out too quickly to keep lit, and their spotlight focus never illuminated much to begin with. Random LED flood bulbs can be had with the same socket, but they were wider. A bit of bent telegraph wire later, it was possible to make clips that hold the new bulbs in place after ahem throwing out a few of the landlord's parts. The flood bulb also seems to cast better light by reflecting off of the walls to get around the humungous new obstruction.

If you don't have a little door like this, it will provide insight, it's low risk—and you might lure a family of Borrowers.

	I was surprised to find that Berlin working-class life doesn't typically include luxuries such as an electric clothes dryer, as fundamental to US citizenship as pre-sliced cheese or cable TV. What one does instead is to take up half a room with a tin pot drying rack, which folds down only to leap up again and mock me as I unfurl it later the same day.

	I ~~live with four people of varied ages~~ and ~~our laundry is a legitimate mini-job for tax purposes~~.		[[File:Final use.jpg\|thumb\|''by Adam Wight, 2024'']]
			I was surprised to find that Berlin working-class life doesn't typically include luxuries such as an electric clothes dryer. The washers, dryers and laundromats I have known were always beloved, but only more so in their absence.

	~~Winter makes this whole deal all~~ the ~~more challenging since cold plus damp equals mildew~~; ~~heating a room is expensive~~; ~~the windows are drafty... and waah did I mention that winter~~ is ~~long cold and dark, best endured from behind~~ a ~~protective shield~~ of ~~fidgety little indoor projects~~.		The mischief one gets up to without a dryer strains the imagination. Strings, fans, hidden rooms; carting sodden rags; dry cleaning…

			What follows is a story of one such adaptation.

	~~For this reason and other factors~~, it's taken me a few years of building up courage to try a clothes elevator. The problem seemed harder than it is, at first: unattainably mathy with so many different angles and lengths to consider... the idea stagnated and each time I ~~sketched it came out obviously wrong and incomplete. The turning point was to learn that pulleys simply change the direction of force, and this direction can be constrained or constant~~.		But still, I blame elitism.

	In other words, the rope's travel is equal but opposite as seen from either side of a pulley. If the pulleys stay put it gets even simpler, and all that's happening in my case is that downwards pulling force on a rope is rotated by 90° at the ceiling, and then another 90° so that it's acting upwards on the load. This is just the fancy equivalent of a 180° turn over a single pulley [img].		For this reason and other factors, it's taken me a few years to build up the courage to try a clothes elevator.

			The turning point came once it was clear that a fixed pulley simply changes the direction of force, and this direction can be either constrained and dynamic, or constant. I like constant.

Anyway, it's cold and dark out by this time, and I'm doing something of ambiguous legality and ethicality in a public place, let's not sweat the small things. I unscrewed the sticks that remained, tossed them into an innocuous getaway stroller and walked back home, hunched over my prize.

	The slats ~~are~~ perfect: hardwood at roughly 2.5cm x 1cm x 1.0m. Beveling the business edges and sanding to 180 grit or so leaves the wood smooth enough for cloth to slide over but rough enough not slip. I forgot to sand the ~~sticks~~ before assembly, it ~~gets~~ unwieldy.		The slats were perfect: hardwood at roughly 2.5cm x 1cm x 1.0m. Beveling the business edges and sanding to 180 grit or so leaves the wood smooth enough for cloth to slide over, but rough enough to not slip. (I forgot to sand the slats before assembly and it became unwieldy afterwards. Hopefully dear reader you will remember if the time comes.)

Bending whatever metal strapping around the pulleys is fine and leaves me free to use any type of bolt appropriate for the mysterious ceiling. The axle should have been simple, let's not discuss how overcomplicated I made this out of a misplaced urge to use up old junk. Just a safety note that if you too choose to hang anything unusual above your head, please make sure that it can't loosen with time.

	By a stroke of luck, I found that the bathroom ceiling included a few metal studs, which I trust to give hints before catastrophic failure, unlike the ancient concrete and plaster powder everywhere else in the apartment. And even luckier, a strange little access door provides a clutch of extra metal to anchor to, all in the spot directly above a door jamb where I planned to anchor to anyway. If you don't have a little door like this, it will provide insight, it's low risk—and you might lure a family of Borrowers.

	The ceiling lights became a subproject: old halogen bulbs burn out too quickly to keep lit, and their spotlight focus never illuminated much to begin with. Random LED flood bulbs can be ~~had with~~ the same socket, but ~~they were~~ wider. A bit of ~~bent~~ telegraph wire ~~later,~~ it was possible to make clips that hold the new bulbs in place after ~~ahem~~ throwing out a few of the landlord's parts. ~~The~~ flood ~~bulb~~ also ~~seems~~ to cast better light by reflecting off of the walls to get around the humungous new obstruction.		The ceiling lights became a subproject: old halogen bulbs burn out too quickly to keep lit, and their spotlight focus never illuminated much to begin with. Random LED flood bulbs can be found having the same socket, but the overall radius was much wider. Luckily, the design lent itself to a bent bit of telegraph wire: it was possible to make clips that hold the new bulbs in place after throwing out a few of the landlord's light parts. These flood bulbs also seem to cast better light by reflecting off of the walls to get around the humungous new obstruction, whereas spots would have been blocked by the rack and clothes.

Which is great, except that when full it can add up to much more weight than is comfortable to lift.

			A block and tackle system was straightforward to make from two pairs of double pulleys, which I boringly purchased at the big box like it is the waning tail of the Industrial Age, and provides something between a 3:1 and 5:1 advantage.<ref>The jury is still out on this. Eyeballing it suggests a 5:1 ratio, but there's still much I don't understand. When I put a luggage scale on the ropes, it reads a 30kg pull before the multiple pulleys, and a 10kg pull for the operator, which is unignorably close to an exact 3:1 ratio.</ref> This part of the junk needs to run smoothly and be unlikely to explode, so I have no regrets about my retreat.
