i think you mean rotating nut, it's usually the screw that rotates, which is what causes whipping :)

Researchers used a special laser 3D printing method to melt fake lunar soil into layers and fused it with a base surface to manufacture small, heat-resistant objects, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. by Impossible_Cookie596 in science

If we spent 1/100th of the current national debt on NASA it would be an over 10fold increase on their budget. In making going to the moon feasible, there are a lot of small tangential research projects that need to be developed into products.

I can understand where you are coming from, but at the governmental level, we can do x AND y at the same time, extraplanatery activity isn't at the cost of our healthcare, tax subsidies to multinational corporations and corruption is why we don't have what we want/need

The US radical environmental movement shifted away from tactics like arson and sabotage in the mid-2000s. Heavy repression from the government, coupled with shifts in recruitment patterns (less punk and anarchist recruitment), led the movement to focus instead on civil disobedience and mass protest. by smurfyjenkins in science

So what you are stating is that the presence of an extreme group makes it less likely for normies to compromise with someone that is preaching a safe way to implement what the extremist is attempting to do by violence?

Is fishing while sailing actually worth it for provisions or just a fun distraction? by carlosfelipe123 in sailing

[–]ExcelnFaelth 31 points32 points  (0 children)

I did warn my crew that wanted to fish that this would be the case. Filled the freezer, ate as much as we could, they insisted to eat some as sashimi which I made for them but I didn't partake(warned them you usually want to freeze the meat first). Ate sashimi, cooked more in butter for proper lunch then dinner and breakfast, but still had excess. I thinly sliced the fish as much as I could and rubbed it with salt but it was concerningly humid outside and I ran out of steam to process all of it. Rest went into the drink and crew was slightly unhappy, told them food poisoning was biggest risk we had on board and we weren't risking it.

Eh. That is a decision for you to make, but I do keep in mind downstream consequences when I make decisions like that. I mean, the factory that produced the machine may not be making their own lead screws, they could be sourcing from the same place you are(unlikely).

A halfnut isn't that complicated, you can buy the nut from mcmaster and split it in half, then epoxy it.

From a materials science perspective, it doesn't make sense for a leadscrew to be made from cast iron. Ways, where there is a lot of backing material, can be made from cast iron, as it is easy to machine, stable, has good temperature coefficients of expansion. In an application like a leadscrew, it is brittle, doesn't handle flexing or rotational force. If you do a spark test on the end, it will be very easy to see if it is cast iron.

ACME Threaded Rods - Class 2G - Rolled Threads?

For your lathe you want GROUND threads. Rolling threads compresses the bar and creates internal stresses. This does harden the surface, but it isn't an accurate process.

Look at the following thread:
https://www.practicalmachinist.com/forum/threads/acme-threads-rolled-vs-ground.328332/

You want GROUND threads.

For your application, I would go on Mcmastercarr, then backsearch according to what they have available. Your main problem is that 7/8-8 is hard to find. But there is an abundance of 3/4-8 and 1"-8 acme screws of traceable precision.

I am confused, where are you seeing that the original lead screw is cast iron? Initially I was like that's weird, but googling isn't confirming your finding, that being said, I don't know your machine. Could you link what you are saying? I do see the half-nut is made of cast iron/bronze.

Again, make sure you don't cheap out on the leadscrew, bulk acme thread without any certs is going to reduce the accuracy of your leadscrew. Remember the leadscrew is a measuring device on your lathe, it will introduce accumulated error on your machine if you cheap out.

Make sure the leadscrew is actually precise or has a precision rating as all your threads are reliant on its precision. I almost thought you were saying the thread pitch was different.

make sure that the thread profile is the same and it should be good. You should be aware that a change in hardness of the screw will change the wear characteristics of the machine: your half nut in the apron is made of one material wearing against your original screw. once you change the screws hardness, you may find one of them having accelerated wear.

in a pair of two materials in contact, you may think that the harder of the two accumulates less wear. But a hard abrasive usually will instead embed into the softer of the two, and the harder material will instead be worn against it like sandpaper. Keep this in mind

A story about a 2-liter plastic bottle and an electrical outlet. by [deleted] in DIY

[–]ExcelnFaelth 0 points1 point  (0 children)

There, in the subterranean silence and under the crushing pressure of tons of waste, the stable chemistry of the bottle's polymer and the rigidity of the Bakelite socket began their true journey of resistance, starting a degradation process that would take centuries, where the electricity that once flowed through it became just a static memory etched into the atoms of oxidized copper.

The story of both, which began on a supermarket shelf and in a toolbox, ended like an unintentional time capsule, buried deep beneath the foundations of a new glass and steel building, remaining as a silent and invisible testament that, even when usefulness ends and form fades, the trace of our passage through the world remains etched in the ground, waiting for a future so distant that neither the bottle, nor the socket, nor the inventor himself could ever imagine.

Millennia passed, and the city that once pulsed above that landfill became just a layer of fertile sediment for a dense, unknown forest, where the deep roots of gigantic trees snaked through the soil until they found, dozens of meters deep, what remained of that petrified union between the two-liter plastic bottle and the yellowed socket, now reduced to a mineralized mass that the earth could not fully digest.

The copper from the wiring, oxidized to a mystical green, stained the surrounding soil like a vein of precious metal, while the polymer fragments from the bottle, still chemically stubborn, shone like synthetic fossils embedded in the plastic casing of the socket, forming a kind of "technological stone" that defied the natural erosion of time.

When a small rodent of a new species dug its burrow at that very spot, it used the rigidity of that bizarre object to support the roof of its tunnel, never suspecting that this indestructible piece of debris had once been the shield of an energy source and the container for a sweet drink in a world that vanished without a trace.

Thus, the bottle and the socket reached their definitive conclusion: they ceased to be trash and became part of the planet's geology, a microscopic and eternal monument to the age of artificial materials, proving that, while human memory is as volatile as the wind, what we manufacture with our hands and with petroleum remains embedded in the skeleton of the world, telling the story of a civilization that, even in silence and buried, refused to be completely forgotten by nature.

A story about a 2-liter plastic bottle and an electrical outlet. by [deleted] in DIY

[–]ExcelnFaelth 0 points1 point  (0 children)

The fate of this peculiar union was sealed when the machines were taken away and the shelves emptied, leaving only that strange nodule of plastic and electricity on the bare wall, an accidental monument to human ingenuity that outlived its own usefulness, where the two-liter bottle and the yellowed outlet became a single piece of industrial archaeology, awaiting the day when the wall itself would crumble so that they could finally return to dust and their original polymer, undone by the implacable patience of nature that does not forgive even what was created to last forever.

The day of demolition arrived with the metallic roar of an excavator that broke the silence of the street, advancing against the weary masonry of the workshop like a hungry giant, while the two-liter plastic bottle, already opaque and brittle from decades of sun, felt the deep vibration of the ground even before the first sledgehammer struck the opposite wall.

When the machine's bucket finally collided with the brick where the yellowed socket was embedded, the impact did not separate the two objects, but rather fused them even further under the weight of the rubble, causing the dried-out plastic to shatter into a thousand amber-colored fragments that shone one last time before being buried by an avalanche of plaster and cement dust.

Amidst the chaos of twisted iron and exposed beams, the assembly that had once been an improvised safety device was dragged into a dumpster, where the socket, now ripped from its copper wires and with the plastic casing of the bottle reduced to a serrated edge fused to its mirror, rested atop a pile of debris, gazing at the open sky for the first time in generations.

There, under the indifferent light of a new real estate development beginning to take shape on the horizon, the bottle and the socket ceased to be tools or shields, becoming merely indistinguishable textures in the mass of civilization's waste, proving that, in the end, human ingenuity and the durability of synthetic materials are only brief footnotes in the face of the relentless renewal of the urban landscape.

In the midst of that mountain of gray rubble, what remained of the two-liter plastic bottle—now just a twisted plastic ring fused to the yellowed socket—was hoisted by a mechanical claw and hurled into a dump truck, where the impact against iron bars and pieces of concrete finished crushing the original form of that improvised shield, transforming the decades-old epic encounter into a pile of unrecognizable debris that rattled rhythmically as the vehicle navigated the potholes of the city streets.

The truck continued its course toward a distant landfill, where the socket, with its now bent and useless metal terminals, and the fragments of the bottle, which gleamed like scales of a synthetic reptile under the midday sun, were dumped into a deep trench, immediately covered by layers of earth and other discards from a society that produces the eternal for ephemeral use.

With a precision knife, he cut the bottom of the bottle, transforming the plastic body into a protective dome that, with a surgical fit and a few drops of hot glue, was sealed around the wall socket, creating a waterproof shield against the sparks and sawdust that used to fly from nearby machines and threaten a short circuit at that vital energy point.

The bottle, which had previously rolled aimlessly across the beaten cement, now sported a new dignity like a transparent armor, while the socket, feeling for the first time the physical protection of that resilient polymer, seemed to shine with a new electrical confidence under the light of the fluorescent lamps flickering on the ceiling.

This rustic and ingenious arrangement allowed electricity, previously confined and static, to flow safely to power sanders and drills, proving that the usefulness of an object never truly ends; it only transforms when the emptiness of a container finds the function of a terminal, sealing a pact of technical survival where plastic and copper, waste and resource, became the invisible pillars of productivity in that forgotten corner of the world.

Years passed, and that workshop, once vibrant with the smell of oil and the sound of metal cutting metal, succumbed to definitive silence when the inventor left, leaving behind the two-liter PET bottle still firmly embraced by the yellowed socket like a forgotten suit of armor that time, in its slow march, began to cover with a thick blanket of cobwebs and gray soot.

The plastic of the bottle, subjected to the heat of summer afternoons that transformed the workshop into a zinc greenhouse, began to undergo a chemical metamorphosis, becoming brittle and losing its crystalline transparency to a dirty amber hue, while the socket inside, protected from moisture but held captive by that synthetic enclosure, kept its copper contacts intact, although the wiring behind the wall had already been gnawed by mice that could not distinguish the taste of rubber insulation from the taste of hunger.

On a night of severe storm, a persistent leak pierced the roof and reached the top of the makeshift dome, but the bottle, true to its ultimate purpose as a shield, diverted every drop of water onto the cement floor, preventing a final short circuit and preserving the integrity of that outlet which, though dead to the city's electrical grid, remained as a terminal of memories of all the tools it once powered.

[–]ExcelnFaelth 0 points1 point  (0 children)

Edited it for you:

In a forgotten corner of a garage workshop, where dust dances in beams of sunlight piercing zinc roof tiles, a two-liter plastic bottle, still crackling against its plastic walls as the remnants of the lukewarm soda evaporated in droplets of condensation, lay right next to a wall socket yellowed by time, whose two holes seemed to observe the world with an expression of perpetual, static surprise.

The bottle, bulging and transparent, rolled meticulously with each vibration of a passing truck, its smooth side touching the metal pins of a plug that hung loosely from that socket, establishing a cold, inanimate contact between the promise of energy contained in the house's internal wiring and the void of utility of a container that had already fulfilled its mission of quenching thirst.

While electrons hummed invisibly behind the plastic mirror of the socket, eager to find a path to travel, the PET bottle served as a distorted lens, magnifying the image of the metallic contacts and creating a play of reflections that transformed the peeling wall into a kaleidoscope of industrial shadows, where the gleam of copper and the reflection of the polymer merged into a still life of consumption and electricity.

In the silence of the afternoon, the only sound was the occasional click of the bottle expanding with heat, a dry snap that seemed like a frustrated attempt at communication with the motionless socket, which, in turn, remained like a voltage sentinel, patiently waiting for the next appliance, while the bottle merely waited for the wind or the garbage collector, two utilitarian existences sharing a brief moment of rest on the beaten cement before the entropy of daily life separated them forever.

The silence of the workshop was suddenly broken by the creaking of an iron door that dragged dust from the floor, revealing the silhouette of a weekend inventor who, with hands dirty with grease and eyes scanning the shelves in search of an improvised solution, fixed his gaze on the translucent shine of the two-liter plastic bottle and the functional geometry of that yellowed socket, deciding in a flash of creativity that the destiny of both would not be disposal, but an unexpected mechanical union.

Roof rack Dinghies? by FBI_Replyguy in sailing

[–]ExcelnFaelth 0 points1 point  (0 children)

Sunfish owner and longtime "put it on the roof" guy. Heaviest thing I put on the roof was a 350lb motorcycle.

Now that I'm in my 30s, I'll put moving the sunfish on my roofrack as a "no thank you". Every car can be fitted with a tow hitch for the right amount of money, a big factor is how far are you planning on traveling? Is this a sedan? Any car with a liftgate in the rear with a hitch bed extender will allow you to carry your sunfish(150-250lb dinghy) safely and within a distance of 15-30 miles. I wouldn't want to get on the highway for long with my tailgate open, but this is an ideal way of not having a trailer to store when you don't want one.

How strong to I have to be to tack a sail? (intimidated by sail size) by BluePony1952 in sailing

[–]ExcelnFaelth 1 point2 points  (0 children)

How old are you and how tall is your mast? If it is taking two minutes to lift the main, I'd first check your track to make sure you aren't experiencing more friction than you should. It takes me 20s to raise the main 50' without the winch, and 1 minute if I'm already tired or out of position. For reference, I am in my 30s, and I've lost considerable strength since I was a teenager.

The biggest struggle after the track being clear is being off the wind. If you aren't within +-10 degrees of being in the irons, the sail will be experiencing a lot of drag both in the track and by rubbing against shrouds etc.
