Opening a glass jar with a metal lid is easier the greater the temp difference between metal and glass. metal expands reducing contact patch and friction making it easier to open. Glass has little to no movement it is a amorphous solid, read liquid.
When she hands you the jar rest your warm hand on it and start talking, seconds count, I recommend self aggrandizement.

Rub your wood screws in fireplace soot/gunk, decreases resistance letting you drive deeper and is an anti-rot agent. Similar stuff pumped into pressure treated wood.

The screws allow the lighter to be used as a bottle opener. They also help make the lighter denser than water, so you can use the lighter as a fishing sinker.
You can partially unscrew one of the screws to allow the lighter to stand upright on uneven/non-level surfaces.
If you put the screws around something like a railing or a rope or chain of adequate thickness, the screw heads will prevent the lighter from being easily misplaced or stolen. It would be a similar concept to the pens on chains that you might have seen in some grocery store counters.
In a DIY emergency you can remove the screws and use them to screw things together.
In a water emergency you can remove one screw and drink the contents of the lighter.

It literally explains that it works better with some metals and not others in the fuckin loctite instructions.
It’s a common myth/misunderstanding that it needs an oxygen-free atmosphere to cure. It doesn’t *need* it to be oxygen-free, but it *can* cure in an oxygen-free environment in the presence of metallic ions.
This is the same effect as “japan driers” which are metallic additives that polymerize paint faster. Usually poisonous metallic salts, cobalt based for example.
And yes, nail polish works well, too. If you wait long enough.

I didn’t snap a pic, but I actually began doing it to a little 4” pittsburgh pair of cutters like that. Unfortunately, it was the nippers from that <$10 6pc mini pliers set, the ones with the black and green grips. Those pliers were so awful straight out of the box, the end nipper jaws weren’t even or straight and they struggled to cut 8”L generic cheap zip ties even with decent hand strength. Plus the rubber grip starts slipping around when you get past mild gripping effort.

And after grinding the front, I tried to sharpen the jaws but it’s difficult to get a good angle and I struggled to get the thing to cut small zip ties any better than before.

The CA stuff? Doesn't that activate and harden because of ambient hydrogen in the air? It's not oxygen, sure, so it does harden anaerobically, but that doesn't mean you can just leave it out, because hydrogen is in the air.

No, anon. Threadlocker undergoes anaerobic polymerization. That doesn't mean you don't need oxygen to cure it, it means that oxygen will actually prevent it from curing. Being trapped between threads with the majority of the air squeezed out is what gets you that anaerobic environment necessary for it to cure. What actually catalyses the reaction and starts the curing process is contact with a transition metal. This is why most threadlocker either won't cure or cures very slowly with certain materials, such as Stainless Steel fasteners in Zinc or Aluminum. It's also why it's important to clean your fasteners if you want your threadlocker to work correctly.

Want to ruin a bottle of threadlocker? Squeeze some out onto a piece of copper, then suck as much as you can back up into the bottle. Now put the lid on and marvel at how the whole bottle cures through in a week. If you leave the lid off, it won't cure as quickly or thoroughly.

This has been on my mind for a looong time.
Build a small solar powered drone that serves as a comms relay. It builds up potential energy by flying to a high altitude during the day and slowly ascends during night. That way you don't have to carry a massive amount of batteries to survive the night.

I would not build this because It is illigal to fly your drone higher than 200m where I live but this would be a fun project nontheless for SHTF situations.

There are many problems with this. Not least of which is that air gets thinner as you go higher. This means you need more and more power to get less distance. And you will generate less power on the way down.

Second, long distance solar drones are gliders. Turning in a circle like that is going to lose you a lot of lift/energy.

Third, your communication equipment needs power and is going to be heavy if you want to use it for more then just a toy.

>> No.2864772

>>2864734
>I would not build this
You can however do the math. Find out how much energy (Ein) it would take to get to a given height (H). This should be available if you read papers about long distance solar drones.

Then find out how much energy (Eout) you can extract on the way down. This will give you your efficiency and allow you to calculate the weight and power of you payload.

One thing to remember, as >>2864746 points out, that getting to 2xH won't take 2xEin. It will take Ein + df x Ein (where df is your density factor). And you will only get Ein+(Ein/df) energy back out. In other words, the higher you go, the more energy you spend and the less energy you will recover on the way down.

And it should be pointed out that there are far simpler ways of storing energy as potential energy. And if this is for SHTF, simple should be your guiding light.

Yeah but that would also decrease drag on the prop and the airframe which in turn would negate the effect of lost efficiency.

>Turning in a circle like that is going to lose you a lot of lift/energy.
Also the sun does not look like my pic. Quick question: Imagine how you would have felt if you had no breakfast yesterday.

>your communication equipment needs power and is going to be heavy
Nah I would use LoRa which is low power and very lightweight.

>>2864772
I very much like your approach!
Lets say the whole thing weighs 1kg and the airframe achieves a glide ratio of 1:48 with a glide speed of 8 m/s.

Now lets say the time between sunset and sunrise takes 12h. During that time the drone would glide 5400 meters and would drop 900m.

During the day the energy required to get the drone to the required 900m before sunset would amount to 8826 jules of energy or in other words it would use 735 W/h on its way up.

The solar cells I have, produce 60 W/h of power so I would need ~13 Cells to get to 900 meters.

Seems doable to me.

At 8 meters per second, it would take 11 minutes and 15 seconds to travel 5400 meters.
In 12 hours, it would travel 345.6 kilometers

Welding is join 2 pieces of metal by melting them and they fuse together as they cool. I very much doubt you are doing this with copper pipe. You are probably brazing them, which is where you melt a 3rd metal and it cools and joins 2 pieces together. This is also called soldering and is what is normally done with copper pipe.

The secret to a good braze is a clean surfaces and flux. For copper pipe, you very much need to empty the pipe.

Because those specific videos you posted, Todd’s trying to see if a linesman plier will cut through a socket adapter, which is sort of retarded. Some of his videos are informative, but typically with cutting tools, most people want something that will cut well for a long time, not a tool that will cut through something absurd once without snapping in half but have a super dull cutting edge by the third time.

If you watch the more recent end cutter video, or like the mini bolt cutters, the stuff where he starts going through drill bits and hex keys with tools that are made for cutting that stuff, you can see how the Knipex steel starts to shine.

On the Cobras and other pliers, they feel the same as cheaper pliers when you go to grip pvc or copper, but by the 100th use and you want to grip something made of steel, the cheap tool is going to slip and slide while the tool with proper metal and hardening still grips great.

Knipex makes pliers since 1882 and they make only pliers, they have great quality for a fair price (in Germany) i know there expensive in the us. they never disappointed me and always are great in quality and performance.

Dewalt or Irwin are not Pliers producers there are general tool brands, idk if they make the pliers themself or buy them form somewhere else like knipex or NWS, Look at this pic they all look suspicious similar made in Germany by NWS . Nowadays the Milwaukee pliers are made by someone else Maybe they are Taiwan or Chinese now, idk if they are good or crap, so why would i buy them if i can buy knipex i have CGP Knipex pliers which were made before 1942 from my grandpa and they still work fine.

I don't understand that Brand love that exists on /diy/ anyways.
I wouldn't buy Screwdrivers from Knipex since they buy them somewhere else to complete their assortment i buy PB-Swiss, Felo or Wiha.
but i don't buy Pliers from Wiha since they buy them from Taiwan. and i don't buy wrenches from Wera (those are shit) their screwdrivers and Bits are on point. but they are not a wrench drop forge company that is what Stahlwille does since 1862 and is great at.

Those NWS Irwins were a real limited thing a few years ago. They weren’t cheap either. Wish I would’ve grabbed some when they went on clearance after that little partnership ended. NWS isn’t sold much at all in the states so they’re quite expensive where you can find em. The regular Irwins are all good enough, not cheap crap, but they’re made somewhere in Asia and not really a premium brand. Just another brand owned by Stanley Black & Decker for mid level tools.

My main 10” channies in my go-bag are the Kleins made by NWS, but those weren’t sold very long either. They found a USA manufacturer more recently and I never bought them but they don’t look as good as far as shape and ergonomics and sharp teeth.

Well if you’re in the US, I’m sure you won’t see much NWS because there’s like one website that sells them and the Amazon listings for it are mostly Italian and such. Knipex actually sells on and off at US retailers and has a big Amazon storefront.

Whatever NWS was manufacturing for other companies, I haven’t seen it. Those Milwaukee NWS pliers must be quite a few years old, especially since Milwaukee has its own US factory these days for their more premium pliers.

I have a feeling the “Made In Germany” stamp on the Klein pliers I have wasn’t a huge selling point for their customers. Klein and Milwaukee can sell their USA tools for a premium price because so many union sparky guys love seeing that American flag.

Didn't see a dedicated pack out thread but figured this was close enough.

Long story short, new job assembling 98% of the time bikes from kiddie snap togethers to $400 mmountain bikes. This is a traveling job that is being outsourced almost exclusively at walmarts. So all work is done indoors, no rough terrain. I don't need a shit load of tools but I do need to be able to fit about 4-5 impacts and a bunch of wrench sized specality tools and general wrench and deep wall socket sets. From my SUV I have to move a 40lb bike rack, 6ft folding table, 2 gallon air compressor, and my tools. Typically in a shopping cart so I am going to have to lift this thing in and out of a cart.

I do not have a done of cash and I have to buy a bunch of these tool to be able to handle all orders or I have to decline a bunch of work since I'm lacking equipment. All I know if my oversized tool bag is just really a pain in the tits to transport all these items. I can make it work but it is messy and disorganized.

To the point of this rambling of a post. Given the low pimact nature of the job, working indoors, and the importantance of mobility and weight. What are your thoughts on the HART pack out system? They got the 3 piece deep tool, medium tool, and see through organizer on sale for $74 at walmart right now.

Denali is Amazon’s private label tools by Skil, sort of like how SATA is Amazon’s Gearwrench.

Some of that Denali stuff is too good of a deal to pass. The Skil tools tend to be pretty good DIYer tier, and then the Skilsaw branded stuff is heavy duty. I snagged some Denali glass/tile bits because they were so cheap I couldn’t not buy them. I have the Milwaukee version with the smaller 5 sizes, and with limited use, the Denali ones don’t seem too bad, and I normally hate cheap consumables but these are definitely better than chinesium no-name.

Also for Denali anon, if the battery went bad, keep an eye on sale at Lowe’s. They have that Skil 12V/20V on sale/clearance for real cheap pretty often and if you could snag a 20V drill/circ saw kit with a couple batteries for $79 or something stupid, and the batteries work on that Denali, that’s a nice beater or loaner tool set.

That guy screaming about altitude is dumb as hell. Planes are most efficient around 30-40kft just under the speed of sound.

That said you're not going to get 8-16 hours of gliding at night, especially if you're switching your engine to be a generator and automating the flight.

Big boy planes usually have a generator like this for power failures but they're also trying to land immediately. It only very slightly effects their optimal glide angle but that's not very good anyway.

Also, probably common knowledge to non retards but I'm not part of that group, you can buy 6x strength vinegar at the hardware store way cheaper than the piddly watered down stuff at the grocery store. I spread salt around the sides of my house then pour buckets of the stuff to destroy weeds without using glyphosphate and it works wonders. Keeps ants and moles away too.
It's a 100 year old postnpier, the previous owner planted bushes all around then wondered why he had so many ants. Now I have bushes on the other side of the driveway and side path, and nice weed&ant free lava rock around the house. Much nicer.

Useful my ass, good way to fuck up the port. Cables aren't expensive, neither are the plugs and crimpers.

It literally doesn't help, I carry a bottle of clear nail polish with me just for this.
