Board: /diy/
"/diy/ - Do It Yourself" is 4chan's imageboard for DIY/do it yourself projects, home improvement, and makers.
Welcome to /diy/, a place to:
Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.
Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

I did my first casting today, I'm totally a foundryman now. My first two melts earlier in the week I made some ingots, just melting soda cans. >>2783890
Yesterday I made my first flask from a spare fencepost, and some greensand from sifted playsand and a mix of sodium bentonite and calcium bentonite. Yard marking calcium carbonate as parting powder, worked great. Designed a little ashtray in Fusion360 and turned it into a pattern. I did a pretty bad job but I was impatient and really wanted everything ready to do this casting today. Rammed up fine, might've been a little dry, but just barely. Worked out okay though, very happy with the result after a brief cleanup.
Do you scrap? Stack? Do you sell signs on Etsy? Do you sand cast? Investment casting? Do you like huffing zinc fumes and snorting silica powder? Show me your furnace, show me your castings.
Sand and jpeg compression don't get along.

Is there like a way I could vacuum transfer it? I have an old shop vac and a leaf blower/sucker combo thing. I was thinking maybe if I just don't put the shop vac base on, or the leaf bag, one of those might work to like spray it into the bed. Or maybe that will just destroy them.
Is there something like that? I'd buy one. Otherwise I could rent a loader but I'd also have to get it delivered and picked up, that gets kind of pricey. how do i make my room better?

greetings,
i bought a second hand mower and its giving me somewhat trouble.
First of all, it never ran right since i bought it a few weeks back.
filter and plug were replaced. I had to change the throttle as the plastic one broke and since it never ran right it obviously needs a carb readjustment.
The manual says adjust throttle cable (green circle) until the screw (missing, red circle) touches the casting. Since the screw is gone i have no fucking idea what the factory setting here is for the governor tension.
Step two would be to lean the engine (screw orange circle) until the revs drop and then turn back half a turn, but if i lean the engine with full throttle it will rev way past 4000 rpm an i know this is not safe to do
How the fuck do i readjust this? what is the proper order here? Also, how does this thing choke itself when cool?
The engine is a 185cc 3hp L head >acquired a decent set of quality tools by now
>Even own a drill press
>barely get any use because appartement retard and there's no space for anything
What else can I do besides working on my bicycle, disassembling kitchen appliances for scrap metal and do the odd car fix on the fucking street because I don't have a garage either?
I can't move so I considered buying a small plot land and build a shack there but then I will get my tools stolen by a crackhead if I move it there, won't I?

Go away Is it gay as a man to order sewing kits online so I can repair my socks DIY style? All the darning tutorials I see online are made by women. I want to do some stuff and I need a rotary hand tool. Some stuff includes maybe hitting a PC case and some wood.
what do I get? >holds the world together >commercial brewing legal advice edition What's the weird crap above my curtains? I've been training tae kwon do for some time and I saw that there is a necessity of recreating some sort of detection on the armor. To give more context, in the major competitions, there are sensors in the armor that are responsible for detecting contact and the amount of force applied. I'm wondering if I can replicate it with an arduino and want tips on this.
What I've found so far is that it is possible to use FSR sensors, but they are not good for measuring a scale of force. So I should be able to use load cells with an Arduino and a HX711 amplifier module.
Any tips on doing this whole project? Hardest part for me might be inserting it all inside the armor. 1. Can I put up drywall on this box or does the bottom need more support than the 4 corners?
79in long (6.6ft), 24in wide (2 ft)
2. Do I need support for the drywall all the way to the edge to the wall where the railing is coming out of
(14.5in long gap) I broke of these pic related stoneware mugs and am thinking of doing a faux kintsugi thing. However, I also want to be able to microwave this thing, so JB Weld is out, epoxies are apparently out (temperature issues and potential fuming or whatever when exposed to enough heat), and superglue was never practical to begin with.
Unless someone has any better ideas, I was thinking of resorting to a cement mixture of some kind and sorta painting on my gold (mica) pigment onto the cracks and then figure out how lacquers work. how I stopped that nigger from stealing my wrench. can i replace a 320x240 54 pin lcd with a 640x480 54 pin lcd ? What would be the cheapest way to accurately cut this shape out of a 3mm (11 gauge) piece of steel, without access to expensive machinist tools?

There is no defined starting point, grab a book and start reading or buy an arduino off ebay/amazon and start messing around. There are a plethora of examples online to get started.

Sure, there's plenty of mass production brands out there at the stores.
Those work OK if you're dainty with them.
But does anyone know where one can get heirloom quality hoes?
Hoes that can take a real man working the dirt with them I want a geodesic dome addition on my house. I want size picrel. I know this is masochism.
Question is how would you go about this? I was thinking metal frame with premade adapters at the corners to properly angle the whole thing. Pair that with premade triangle panels in wood frame with glass installed. I think this glass part is where the money will end up. A place for anything to do with Welding.
Post your welds, ask questions and discuss sticking metals together.
IDK I just want a place to talk about welding. Do they literally just blow warm air over the food?
some of them cost over £500. I already have metal boxes and hot wind isn't exactly hard to attain. How horrible would it be to live under somebody running 4 of these 24/7? I'm trying to imagine what life is like for my neighbor right now. I want to do stuff like pic related, clearly starting with something smaller and work my way up, have some space, have not too much money but I have time.
I don't know anything about stone, how do I start? Just buy a hammer and chisel and carve away? How much will it cost to have this ceiling replaced? Hate mould But like what is this yellow discolouration on the ceiling? Mould?
Coldish climate I want to construct a similar design (an "invisible" chair that makes you look like you sit in the air) and I need the name for that part. It's a thing that would link two metal bars together, allow them to fold, but stop at a 90 degrees angle. How would you call that part? Do you know where I could find it? Why cant it be at ground level? I'm not an engineer, I just like to make stuff. Naturally, lots of the content I watch often happens to be made by engineers (or engineering students), and seeing them go about making things sometimes makes me wanna kms. You've got a team of 5 dudes making a rc car, each bro i would assume assigned with his own task, trying to calculate every single thing that could possibly be calculated around said rc car before they ever dare to assemble the real thing. Listen I get why the methodology exist and I'm grateful for it, I don't want our buildings or bridges or commercial airliners to be eye balled, but following this workflow whilst trying to create something new is grating to watch.

I have bought this set a couple of years ago for a great discount, is this hair clipper a good model which should last me years?
The hair clipper is a Wahl 09243-2616 and doesn't use a battery Hey yall, I've been thinking of starting a commercial vent hood cleaning business with a couple buddies being that we all have restaurant experience. I'm already thinking of chemical costs and basic shit like scrapers/ an LLC, any suggestions or tips about anything I'm not considering?
General diy business thread if nothing else I want to get an electrician or HVAC apprenticeship, but I can't take a pre trade course. What are some ways I can teach myself so that I can show I have some idea of what I'm doing? What would be the best method of supplying wired internet to multiple buildings over say 10 acres of land spread out?
Not necessarily the cheapest nor the highest bandwidth, just running wire to different spots that are going to go through one isp bill? For the last couple years, I've been keeping one of these with gas in it in my garage, like it's no big deal.
I'm starting to get the idea (Googling and skimming through some of the links) that's a really fucking retarded move, and I'm having trouble coming to terms with that.
I'm hoping people here can convince, me it's not that stupid or it's not even bad so I don't feel like a total fucking jackass with these mistakes like I do all the time. for leatherwork, you need a very dense material to tool (draw) and stamp on. We all have little granite slabs. I make luggage and messenger bags almost exclusively so that little slab is just top small. 2x3x8 slabs of granite are reterdedly expensive.
here are a few factors I'm considering.
1, my house doesn't have a concrete foundation so reverberation will just always be an issue. I want to get as much force transferred onto what I'm working on as possible.
2, I have read that a work bench the size I'm going to make will weigh 100s of lbs.
3, even the best concrete tables eventually Crack, sometimes within a year.

I dont want to pirate it unless its only option. Hello, I'd like to build something to keep my voice very low and allow me to train silently (or with less noise at least), do you have ideas/encountered stuff like this already ? Ideas of materials ? I was planning on using pillows and blanket, any idea ? Birthday was a week ago. Went ahead and got a new pair of boots out of the attic that I've been hoarding for a while. Got tired of my socks getting soaked every time I got in water up to the sole of my boot. Probably still wear the old ones when I'm not irrigating and it's dry, or at the shop to get a bit more wear out of them... Fringy things on the new boots were cut off on day 1.
Any tips to keep the soles from cracking around where the leather stitches to them? That seems to be the placed where water intrusion starts. Should I put a fat bead of urethane windshield adhesive on my old ones and see if I can waterproof em again?
Also workboot thread. Post em up. I am tired, I don't want to deal with hunting shit anymore. I just want to input money and receive stuff without it being a knife fight over some old junk worn out machine that'd been out of production for 70 years and I have to get raped to get replacement part on ebay by some other boomer.
Are chink mini lathes viable to get running well without needing another lathe or a mill to fix the brand new machine you just bought? I just want to make small steel items, maybe up to an inch in diameter but realistically 5/16 or smaller diameter machine screws. Hello /diy/ quick question: why not put your meat birds in a cone upside down and decapitate them with like a cigar cutter mechanism? Why bleed the animal out while it's brain is attached and it panic when I could depart it's brain from body and bleed it's body anyway? Heck I could fill a bucket with warm water and clove oil and toothache herb to Chuck the head in so it doesn't feel the passing seconds of residual brain signal.
Unrelated garden picture. The design for this thing is so compelling, but most of it is a gaming thing. What features would you have built into it for doing real things with it while having your hands free?

Anon other tips? 
In short: What modern material is the opposite of carbon fiber? Looking for an extremely high strength:weight ratio, but in compressive strength and not tensile.
I've made a number of bows using various woods before, familiar with the process generally. However, one thing that always stood out to me is the lack of innovation in the field. When it comes to bow construction, the back (ie the side facing way from you) is always under tension. In traditional style composite bows, sinew is used. Carbon fiber has replaced this for obvious reasons.
The issue is that I am completely unaware of anyone looking into what would be an ideal material for the belly of the bow (the side you see facing you). This side is under compression when drawn. Some research suggests that phenolic resin has been used successfully by custom bowyers, but surely there are other materials that would surpass it in compressive strength:weight ratio.
For reference, my goal is to build a manchu style composite bow from modern materials.(Pic rel) How to I strip the paint off an old, heavy duty steel PC case? and any tips for repainting it
I have a belt sander, a detail sander and an angle grinder but I legit don't know where to start I'm worried about hammering nails into wires when I'm hanging paintings.

why do people talk shit about briggs and straton engines? it just keeps running what does one do with these items, and why does one buy them while wearing black plastic gloves? 
I live in a small apartment with my girlfriend, and lately I've noticed that one specific corner of my wall, in the living room, is starting to bubble out. I believe it's sheet rock walls with spackle slapped over it, and possibly painted over. I don't know if it's sudden water leakage, because of the stains, but the ceiling itself isn't bubbly or mushy. I don't hear water dripping, and the wall isn't wet when it rains outside. My landlord doesn't care at all.
So anyway, I was thinking of scrapping the spackle away, it's about a 2x2ft section. Then just applying some. There doesn't seem to be any pattern that they used, if you look at the wall they kind of just went crazy with it. I was also thinking of using some sort of sealant where the wall meets the ceiling, it looks like they did that before. Is there anything I need to know before doing this? The spackle is currently so crumbly that I feel like I could scrape it off with my fingers. But I have a putty knife and am going to borrow a shopvac and just scrape it off and spackle it up. Seems pretty straight forward, I just feel like I'm missing something? Do I need to prime something first...or just do it? Post what you've acquired recently and why little paypiggies Hi /diy
With a fella at my astronomy club, we're interested in the making of a binoscope.
(pic related: it's 2 telescope side by side)
There seem to be awesome realizations on the internet, but close to no diagram or advice.
This is a 3 stage project:
1- we'd like to try it out with 2 newtonian telescope (skywatcher 200/1000) since we have the same model.
2- make a small frame that would use these mirrors (2x200) since we're not experienced in the telescope making business
3- scale it up to 2x300 or 350mm.
My biggest concern is finding good secondary mirrors, since they'll need to be bigger because lower on the light path.
Any diyer experienced in the field? So my toilet started moving from its place a while ago and now its leaking shitcumpiss water like picrel.
Tried to move it deeper into the connecting pipe but to no avail, the puddle and smell persists.
Is there a way to fixing this without changing any parts or calling the plumber ?

Hell you could even live on it. 
anons im having trouble selecting ideal transistors for use with an RF amplifier design < 100mhz. It seems that the tradeoffs are just too great- you either have low impedance gain or high impedance gain, and you either have low current and low noise but also poor handling, or high current and higher shot noise. rBB is a big part of this and is rarely documented, because it's usually lower than other noise figures. beta is sometimes very high but this isn't necessarily a good thing. have been reading a bunch of documents
pic related, this shit pisses me off
whether it's nexperia, onsemi, nxp, zetex, or infineon, choices for good transistors designed for HF are limited and most offer shit noise figures or require end users to test tons of models to characterize what the mfg didnt think important
trying to design a loop amplifier based on wellbrook and has:
good linearity from 5nv to 500mV, positive gain from 100khz-10mhz(used a LPF 2nH capacitor for this)
consumes under 100mA(ideally under 30mA) of current, powers off 3-5V bias-T power insert
really good, low noise figure
have had some good results with phemt but biasing them while keeping self-oscillation down is hard
a few good jfet exist, but the square law behavior is not desirable
learning transistor behavior has been a giant pain in the ass and it feels like nobody designs transistors anymore for HF
its all crap they designed decades ago >still trying to make something out of my land
Feels comfy bros What's the most autistic trade/skillset and why is it Robotics/Industrial automation? these are the dumbest mfers, just gaping at you. fuck off, there is nothing to see. So housing is too expensive as it is and I've been feeling ambitious as of late. So more and more I've been interested in taking a task like this. I have the know how and I have family that have built homes before that have taught me the ropes as well as would be willing to help, but I'm not sure about having the time at least right now, so it's more of a future project. People are saying 5000 sq ft would cost anywhere between 400k to 1 mil, so 10,000 sq ft they would estimate as more. 10467 sq ft total living space, fireplace, and basement are in the plans. Planning to build on the west coast, Anchorage Alaska, or in a few options in Russia. Foundations are the most expensive thing to build, so I could take care of that to cover labor costs. Does anybody have estimates for this being viable below 1 mil? Or would you say this is pointless dreaming? I have unlimited sand where I live. I want to make it into Silicon for fun, and maybe if I’m retarded enough I will become a silicon mogul and oust Taiwan. What do I do if I want to purify silica from sand and turn silica in to silicon?
I imagine I could use a panning method with water and a rotating pan maybe? Then add crushed charcoal and put it in a furnace to make CO2 and Si? anyone ever pimp one of these mofos out? I decided to under cut my fireplace to install laminate flooring. It turned out okay all things considered. Anyone have good experiences buying a small lot (4-10 units) of 18650 batteries from a vendor on Amazon or Ebay?
From what I gather, they are all sketchy as hell. Even the ones with good reviews seem suspect. The brands don't matter because they place if full of knockoffs (100% real authentic Samsung!)
tl;dr where do I buy batteries? lucky me I think I developed swimmers ear or something after a trip to the ocean. the ear pain sucks enough but it's also putting pressure on my jaw hinge making it literally impossible to sleep. to top it off I have to catch a plane in the morning so 0 chance to go to the doctor for proper treatment.
is there anything I can do to effectively mitigate for the pain and swelling besides tylenol or am I just fucked until I can make it to a clinic? Looking to get into school to gain a degree in CS but figured that until I have enough money saved up to enter school, I can do the learning (via textbooks) now to prep me for later, so I am wondering;
>1.) Any CS Major or Graduate, what or how would you modify this map?
>2.) Most importantly, I am seeking good college text books that covers these blocks of learning Trying to restore a swede jacket that belonged to my friends husband.
Ordered a special brush from amazon. Seems really stiff like it's going to need a really good brushing.

Thanks Any rock or precious metal or precious stone or any flower or any plant or any wood as dry.and as dust is nutritious with any fruit I had to replace the compressor on this thing after 6 years, would like to extend the life of this one. The thing switches it on and off too quickly, under 5 minutes, I've heard this is bad for the compressor, you should wait around 10-15 minutes after turning it off to turn it back on again. It switches that quick because I have a window open and an exhaust fan running 24x7 for important reasons. It still cools down the room very well. How can I change it's logic and set a minimum time before the compressor kicks in? What are the best /diy/ jobs? I have a blued steel screw that I cannot source a replacement for that the first 2/3's of was stripped, the application is relatively low torque and isn't anything crucial, but it only barely engages and if you try to tighten it, it just disengages from the threads without causing damage.
I dont' have a lathe to attempt to make a new screw, and it is not so simple to just be able to make it out some bar stock that's the correct OD and peaning a head to it or something janky like that.
It could be welded, but it would still present the issue of the new material being very hard to machine without a lathe and tap. Brazing obviously would be more favorable to machine, but I do not have oxy to melt brass. Would it be viable to attempt to use a propane torch and use solder to build up the threads in order to retap them?
Threadlocker, copper wire or teflon tape wouldn't be an appropriate fix due to it being need to be removable. Does anyone know of a fair priced powerstation that can run one of those portable tent A/C units or a swamp cooler? It's got to be expandable and last at least 7 hours. I'd like to DIY a whole solar powerstation rig at some point... it's just... what fucking powerstation do I get How do I disassemble this drain in my shower?
I want to take, I assume, the inner ring out, which is I assume, screws into outer ring. I am a rentoid and have no tools beyond Leatherman at this time, but plan to buy some tomorrow). Applying rotation to triangle plastic just bends it to the point of snapping. The goal is to pull the hair out.
Do I buy pliers and just open them up to meet with inner rings inner edge? I feel it it won't do shit beyond scratch it.
Who the fuck came up with this retarded design? I found a whole set of very old Craftsman powertools that someone was throwing out at their curb. I think they are from like the year 2006 or 2007 so they have 19.2 Diehard NiCD batteries that are no longer made. The two batteries they came with are totally shot. I see on Ebay lots of Chinese companies/sellers offering aftermarket for a fairly decent price.
How do I know how trustworthy those sellers/batteries are? Also some of them offer them Lithium Ion, which I don't see how they would they would compatible even though the sellers pretend they are compatible. Should I get suspenders for my occidental tool belt? And if so, what kind? I'm leaning towards the leather ones with the sheepskin pads on the shoulders. I have really bony shoulders and it's painful to carry a lot of wood on them so i was hoping with the extra padding it might help with the pain a bit. >We're going to test that! Got a sheared bolt head, looking at screw extractors. Any recommendations from this page? Yes I know they don't always work, if that happens I'll probably just drill and helicoil it

>Thanks for the help anons So all I have to do to get a job is to go to a construction site and ask for it, despite having barely any experience whatsoever? Who do I ask to speak with? Anyone have an idea what brand this window is? I bought a house and the retarded clean-up guys busted the glass out of the lower sash. To make it worse they took the sash out and threw it away. I can't find a brand or label anywhere. I'd rather find a replacement sash than change out the whole window. How can I install mosquito netting on a European window that opens inwards? I live on the 4th floor, so I obviously can't install it from the outside. Do pumps create flow or do they create pressure? Are you gothic arch pilled?

I've been looking for the dream property for a homestead, and one has recently come onto the market. Had everything I could want: Attached greenhouse, tillable land, fishable stream and move-in-ready house. A few rooms are in need of an overhaul, but nothing I can't do myself. If this were 2020, I would have already made an offer without a second thought.
However, due to inflation and interest rates, I'd have to mortgage the property, and my monthly payments would be 50% of my current income. I don't imagine rates are going to come down anytime soon, and I've only seen 2 of these Goldilocks properties pop up in the last 5 years.
In contrast, I already have 70% equity in a suburban house that I have built up myself and have numerous creature-comforts that would take some years to replace. Remaining payments on a cash-out refi are ~9% of my current income.

>Buy into the dream now & break the bank? All jokes aside, how do I remove cum stains from a carpet without ruining the carpet? The stains are several years old by now. I've had a mouse get into the apartment via an old-school radiator on a wooden floor, and so I'd like to block the area up in this one particular spot. Pic related is a good idea of the worksite. I have the idea to get a metal plate, cut a circular hole with tin snips or similar, and then adhere the plate to the wood (in two cut sections). I am soliciting general technique tips. Haven't had the actual problem for a while but I want the hole plugged up anyway as a further deterrent.
Is the general idea sound? What's a good adhesive to stick a metal plate onto wood? Is there a preferred metal relative to a certain glue? How can I go about cutting/stamping the plate and getting the hole right? The tin snips I have on hand would produce a crude cut on an appropriately thick material, I think.

I just wanna practice and learn the medium, and figured doing it on my own property gives me the experience and practice. Anyone ever tried making their own perfume?

Thanks for stopping by! lost power for a while took everything out of the fridge but there was food residue or something so it got completely full of mold. how do i clean it? will bleach water kill the mold? Gotta take down a whole shit load of trees on my first (and only, but I’m proud of it) property. Probably close to 50 trees across 10 acres.
How many new trees do I need to plant to offset my destruction? 5 for every one tree taken down? 10? I'm trying to learn how to pick locks because I've always thought it was cool, but mostly because my friend and I have to get into a locked place and I thought the skill of picking locks could be very useful.

I live in a part of the country where the humidity rarely goes above 25%. Will I ruin my apartment if I run it with the windows closed, or should I get one that fits into a window? 
ACK-SHUALLY it's *designing* edition
>What is this and why would I care?
Field Programmable Gate Arrays (FPGA) are how poor-fags (<7f plebs) can design a complex IC and test it out QUICKLY at home.
You could design a fairly complicated IC for a small project and use the FPGA as an ASIC-lite (with a flash-storage PCB) or to use your design to get an actual IC etched yourself or in a group-funded chip print. (Like https://tinytapeout.com/)
The basic process is: HDL -> Yosys -> nextpnr -> FASM.
You can also use vendor software from Xilinx etc, but it is very locked down. I would argue it's more convoluted as well.

Trellis - Lattice ECP5, relatively cheap with more power
X-Ray - Xilinx 7 series, Much more money, but lots of advanced features. Not 100% functionality supported with FOSS.

Are there people who unironically believe DeWalt or Milwaukee to be on par with or even better than Makita, or is that just poorfag cope? No shame if they're outside your budget, they're not cheap, but that doesn't make the tools better Disclaimer: i’m not planning to do anything of this. I don’t suggest trying any of this stuff without proper guidance ,knowledge and preventive measures.
Main questions:
is it possible to make a safe, small scale reactor capable of providing energy for a medium class home? How much would be it’s price ?
How much knowledge would be needed to handle such a device? Would a housewife be able to handle it with newly developed technologies?
And if an accident happened:
How large would be the area of effect?

My parents have an older house they bought recently that was added onto over the years by prior owners who weren't the most professional. Some hacky stuff was discovered, but up till now the hot water heater had worked fine.
Hot water goes out so they call a contractor, he finds the lower heating element is heavily corroded and says its time for a new tank, parents agree. A few things about the old tank and power setup: It went 2x30Amp circuit breaker -15 feet-> emergency shutoff (see pic) -> tank. While the old tank wasnt heating water it did have voltage running to it. I ran my non contact electrical tester over it and got the beeps. I barely know how to use a multimeter but I managed to find 120/240v on the upper/lower elements. So it had power but wasnt pulling amps.
About the attached pic: No idea what caused it but clearly that black wire on the right overheated and cooked off the insulation. After cutting back the wiring to where good insulation was and attempting to reinstall it I noticed the threads that screw need to go into were stripped or fucked in some way. Re-using that box without replacing the body there is asking for another overheating scenario.
Fast forward and the new tank is installed but it too has voltage but wont pull amps and heat water. I disconnected from that emergency shutoff box and direct wired to the new heater. Still not pulling amps. The breaker hasnt tripped all this time. It's clearly letting voltage through.
I dont know what I need to test here or how to best do it. I have basic hand tools and a multimeter, even if I don't know how to use it to its fullest. Help me /diy/ I dont want my parents to be without hot water over the weekend + however long it takes to find a decent electrician in TN. 
Okay, I need someone familiar with electricity to explain something to me.
I went into a room with old lighting with lighting fixtures, that was like 20 years old at least. The light bulbs were those long fluorescent lightbulbs a few feet long and 80w.
I turned off lights in a room, but I noticed one bulb was glowing red faintly on both ends in the dark. I looked at it, and it was for sure glowing red. So, I tried to unplug it. It wouldn't unplug, and was stuck, and I tried to force it and felt something snap but then thought what the fuck am I doing? I might electrocute myself doing this and stopped trying to force it to unplug. So, I went to the circuit breaker, and found the circuit the lightbulb was on and turned it off. And then, I went to unplug it, and it easily unplugged. It was weird how it just easily unplugged when it wasn't coming out earlier when it was still on.
Can someone explain to me what happened here? The issue is resolved now because I've removed that thing and have no intentions to ever try to use it. Is there such a thing as a flat head socket screw but with the socket at the tip of the screw, leaving the head completely flat? I would be using such a screw to mount the fascia of a model train layout.

Show me your work /diy/. I've got to know if I'll be able to making it with less than 20k initial investment. Why did no one tell me about them? They are the best for getting marks off a wall My shower in a 5 year old UK house has worked for years without issue, for the last 6 months it has been losing significant (50%-75%) water pressure after the first couple of minutes of running.
I've removed the shower unit from the wall so I'm just blasting water straight out of the pipes in the wall and have the same issue, good pressure for a short duration then very weak, so the shower unit is not to blame.
The tap on the sink maintains 100% pressure indefinitely. I have another bathroom and the shower there maintains 100% pressure indefinitely, as do the sink and bath taps, so it isn't a boiler issue.
There are no obvious signs of a leak.
Can anyone provide advice on how to find the problem? I'm having a hard time finding information on cement roof sheathing.
Is this just not done in the US?
I'm trying to sheath my roof with cement boards, and then put a metal roof over that using adhesive. Cant find shit for information. I had to push wads of grease 75' deep twice yesterday to clear apartment sink drains. Pulling the snake back out was extremely slow and took me pulling as hard as I could for an hour and a half straight both times. I'm a pretty big strong guy, have great grip strength in particular, but I woke up and can't even make a fist with one hand without my joints almost locking in place with pretty startling pain. My shoulders are also fried. If I had to do the same thing today I'd have to flat out refuse. What am I doing wrong? That was the most strenuous thing I ever had to do for work and I've done some rough shit in the past.
