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.Helpful links:https://sites.google.com/site/diyelmo/ (archived)http://www.engineeringtoolbox.com/
Some friendly suggestions for posting:- First ask Google, then ask /diy/. Your question will probably be better received if you do so.- List available resources (tools, materials, budget, time, etc.)- Try to use pictures and explain the goal, if possible- Be patient, this is a slow board; your thread will be around for days.- Share your results! /diy/ loves to see problems solved and projects completed!
I'm interested in learning mechanics and shit and working on cars. I've heard working on lawnmower engines is a good place to start. But I really don't know what I'm doing.What am I supposed to do, take an old lawnmower off the side of the road and fiddle around with it until I've pulled it apart? Then what?I'm guessing I'd want to try and fix broken ones. Anyway as I say I've got no idea what I'm doing and no idea where to start. Is there some guide out there that can hold my hand and tell me what to do?
>>2792697It’s all “Fuel, Air, Spark”. Start with that theory.
>>2792700I... don't follow
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?
>>2792494>smaller chinese attachmentsCeramic cutting blades shatter to easily. Grinding bits are tiny with glue leaks from production (anesthetic issue but it matters).Drill bits (my main use) is of inconsistent quality, haven't dared taking them to steel yet but are still already losing the 'bite'.Bits might come loose in a bag. Then again this was $15 excluding battery and charger. Wouldn't recommend it for anyone knowing they'll use it regularly.
The 4000 series seem bad, they threw out a ton of those at work since they all seem to die.Turns out they are retarded, and I fixed 4 of the 10 by just swapping brushes around, still probably bad odds if you are buying new.
>>2792592good to know. I'm retarded so I better stick to slop.
>>2792597The 4000's are slop. I pulled my other dremel out of the trash with all of the accessories doing a moving job 10 years ago too. I would get one of these side switch models, not necessarily this but I think this design is better engineered than the 4000 since it's the 4000 has a giant plastic transfer bar to actuate the switch, where as these probably are just right on the motor.
>>2792628My man
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. What happened to trying shit out? That's what the OGs did in the early 1900s and it looks a lot more fun than how we're going about it today.
>>2790308That's fair. You can't model absolutely everything in a system using math because the real world has so many variables and it is constantly changing. There still is value in using mathematical models to get the fundamentals of your system in order though just like there is value in considering other sources of inspiration in your design. Engineers aren't mathematicians, but we can use their results to improve our designs.
>>2777290At home I fuck around and find out. At work I run the numbers and do it the boring way, mostly because I need to justify everything. Plus if something doesn't work right, I can look back and compare numbers. When it's a serious project at home I might do some math but not always. >t mechanical engineer
>>2777503>which has terminal Boeing mentalityyou mean they're indian or they want to fill the glider with people and crash into the ground while pocketing the difference?
>>2790644this. it's not black and whitewhen you get paid for minmaxing and have to explain your choices then yes you better do the math
>>2789365That is true for the upper third of the towers and the main structure without the actual sacral half circle. The foundations were already in place when they finally got around to continue it after 500 years.The guy was simply experienced and knew what had worked in France on other churches. That being said it is not without flaws. The main columns along the pews are sagging slightly inward due to having to support the high vaulted ceilings and are actively being monitored. They are simply a bit too thin for their job.Regarding the foundations he went quite overboard with them extending down a dozen meters onto even older churches and made from layered sandstone and granite piles. Which happen to be just flexible enough to make the church quite resistant to earthquakes.All in all a mixture of experience, conservative rules of thumb and an anality to keeping walls straight over their whole height.
Trade Jobs Are DYING OUT...https://youtu.be/6DRm86qmXbs?si=BXi150ZR0VYKCqdQWhy is this so ???? >inb4 >yea low pay is going to be one of the main factors.https://www.npr.org/sections/ed/2018/04/25/605092520/high-paying-trade-jobs-sit-empty-while-high-school-grads-line-up-for-university
>>2792605Nobody wants to put forth any effort to get started or earn their place. They all want the highest paying job off the bat with as close to as zero effort as possible. Oh and they will only put in a maximum of 40 hours a week, not one second more.
>>2792606Yeah, you can find crews to do certain jobs like paint, roofing, framing, whatever. You just do sales and own the place, take all the profit and never touch a hammer.
>>2792606>>2792610And this is why most general contractors become contractors. Because they don't want to do the actual work themselves.Don't confuse licenses with certifications.
>>2791862like what exactly? driving a monster truck at a mine? not too many and normally go to retarded family of company execs and owners."US Navy frigate behind schedule due to staffing shortage at shipyard!" Pay is absolute shit, like when you factor in a few factors, its at or BELOW fast food, with less advancement.I've done construction in Silicon Valley and even on a Public School job with Union Contractors they will use unskilled Illegals to do electrical work on major remodels, and have the real Sparky show up for two days when it gets inspected.
it's not that hard to understand. our parents who were in trades and knew how hard they were working told an entire generation to get some higher education, so they don't have to work so hard. that's what we did. now that sectore is oversaturated and trades are dying. now you can see a reversal starting to happen - I'm pretty sure our kids will get told to get into a trade.but at the same time trade work isn't really attractive when you could get an physically easier job.>>2792082>This isn't "taking advantage" it's just parts of the job that have to get donethis entire sentence, while there is truth in it, shows a core problem. coworkers are tasked to teach new people. often times they have no interest in that, lack any teaching skills, are annoyed that they're tasked to do it or various other reasons. "let them do the dirty work" is one of the worst ways to teach new people. the dirty work has to be done too, I get it. but start teaching the new hire on day one so they become useful as quick as possible while sharing the dirty work. this way the new hire not only feels appreciated but sees that cleaning up and hauling shit is everybody's responsibility. this way you create a much better environment.so as a boss you need to look out for people who want and CAN teach new people too. and preferably not just one dude but multiple
What would you do to your house if money was no object?
If that pic is inside your house I'd say you've already maxed out the potential and can spend all that spare cash on sex, drugs, and rock and roll.
>>2792436buy neighbors house and demolish it and turn that property into a gigantic fenced off back yard and get a big hot tub and make a small skatepark and learn how to shred a half pipe. and put a slide from my bedroom window into the backyard.
>>2792436tear it down, including the foundation, and build a house that has a floor level with the ground.who the fuck thought raised ranch sounded like a good idea?
>better bathroom and kitchen ventilation>turn bathroom into vintage style wetroom while preserving the original fixtures>all new floors>dew proof metal roof>solar array>perimeter fencing>side deck from the sunroom>2nd basement bathroom>buy as much neighboring property as possible
I'm a bit of a fag and would like to create my very own kintsugi necklace.The plan is to buy a few cheap ceramic/porcelain pendants, broke them and repair them using cheap chinkshit sets from amazonHas anyone tried it? Is it possible to do something decent with it?
Hurr durr shipping container homes are a bad ide-https://www.youtube.com/watch?v=NAKY7OWP3rA
>>2789754Basements are good for tornados
>>2791204>have an outdoor service panel on your pole with 240 and 120Vnot a bad suggestion, but what if there is no pole, and the utilities are burred?
>>2792589Then you pay for the standard connection to your permitted outdoor power panel. Those have holes on the bottom too. Trench to your location etc per code which you checked when you got your power arranged with the company. Normally a licensed electrician inspects either and stickers it then the power company activates their meter after plugging it in.
>>2789592$128,000 pretty sure you could build bigger, better framed house, without the weird issues, and still have money left over to buy a couple Containers for storage, or put two on ground with 20ft between them as basis for 2 car garage, with upper elevated patio on the big roof.
>>2792620128 is retarded. Containers are for gearheads to make shops of or to use as singlewide rugged MH. Artfags should be gassed.
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?
>>2789659Whatever you do, always start at the highest point. Bits are very heavy and it's hard to push them up hill
>>2791328>wireless sucks and for something actually reliable and high distance enough it might cost far moreBest to ask /g/ and of course on real tech sites, not just 4chan, because campground wireless is a solved problem.
I just put in a LC singlemode fiber run b/w my house and garage. I used a $120 black and decker edger that can cut trenches and direct buried the fiber into the yard. How long will it hold up? who cares! I think I'm like $250 all in on all the components including SFP+ modules and a new switch on the garage side.
>>2791975Based edger trick
>>2791975>How long will it hold up?Not very long (3-5 years) because fiber is sensitive to moisture and at that sum total you didn't spend enough on the fiber to get direct burial rated outdoor cable that'll protect the fiber from moisture. Moisture will turn it opaque enough to fuck up the signal eventually. If you spend about $30-50 more next time to get that sort of fiber, it's probably going to outlast you (barring some sort of digging accident where you sever it).

Is Idaho hard for people to get? I'm in Idaho but I'm testing for my general next month and still need to put up an antenna.
>>2792533>you're correct that they use the same math we've had for basically centuries.I also remember, in second grade, how school taught us how pilgrims brought antenna math to the new world, hundreds of years ago. They didn't have metal ships, but they had centuries of antenna math.
>>2792617>he doesn't know the Romans had wireless power and radio transmittersngmi
>>2792617The first antennas were built in 1888.1800s 19th century.1900s 20th century.2000s 21st century.Therefore, "centuries" of antenna math.Fag.
>>2792583Idaho is on the other side of the country for me. I got them, but I had to switch to a vertical for SSB and it was terrible trying to confirm my callsign and state with them.
And why do (((they))) insist on calling it hydrochloric acid ?
>>2792527Quit responding youre the pawn faggot
>>2792537implying there isn't a purpose for the options field
>>2775660It can be made by combustion of a 1:1 mix of hydrogen and chlorine gas. There is glassware for this purpose.

Degreelet here and no I am not going to post in the SQTDLGBTQ because fuck jannies and I'm not gay.I want to chop this tree down. My plan is to rent a chainsaw and start with cutting the limbs down away from the house at the top and work my way down.Is this an actual a good approach? It's not particularly high but at it's highest it's definitely a long 25ft thin branch that exceeds my roof line.
>>2792317>he doesnt use an axedo ou also piss sitting down? i bet you call your shit "poop".
>>2792307the ever increasing tree haterspeople just like roasting hot treeless backyards these days
House next to us just sold. New owner hasn’t moved in yet, but they’ve chopped down all the trees in the backyard. People are fucking weird
sorry, but all these tree haters deserve to be chopped into pieces
Exactly how insecure does one have to be to not piss sitting down?
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.
>>2792179>>2792193just literally use your fucking ovenset it to lowest temp and prop the door open
>>2792179If it's something with a low level of water like a carrot you can just toss it into your freezer and it will freeze dry over time. For better quality freeze drying you just put it in a vacuum container with some desiccant which will suck the water out of your produce.Pro side of freeze drying is it preserves better, nutrition wise and texture as well as being faster.
>>2792179Spend 6000 on a Harvest Right then let us know how it went.
>>2792540that is not the /diy/ way, i bet you just BUY things when you need them, don't you? jesus fucking christ.I've tried that method already, made a lot of successful jerky, and it takes >6 hours and costs way more in energy than a dehydrator would.>>2792536pic rel ... if it's that simple, then holy shit, I'll have a jerky making machine up and running in 10 minutes.

>permanently lubricates any metal or plastic>lower friction dry than oil on uncoated metal>improves any oil or grease used with it as it wears>used by NASA on space shit>industry standard coating procedure is just sandblast the part then blast the WS2 on at 120psiIs there anything special about media blasting with half micron particles or will a $100 blasting cabinet do it well enough? I haven't been able to find much about doing this at home, let alone on a poorfag budget. If it's as simple as it sounds, you should be able to coat every moving piece of metal you own for a few hundred bucks. It'd be an excellent application for household stuff like locks, hinges, and tools, and even better for lawnmower, motorcycle, car, etc. engines.Is there something I'm missing here or is this one of the most based materials ever?
>>2792596Never heard of it until this second. Sounds interesting. Will be watching this thread for more info.
>>2792608>twice the load bearing capability of oil>half the friction of oil>chemically inert>works at any temperature>half micron coating thickness won't affect any tolerances or clearancesThe Standard for application calls for a check for adhesion by wiping off any excess and putting on and pulling off a piece of tape. That gives me a little more confidence in trying a cheap setup so I'm probably gonna give it a try anyway.
>>2792596I've never used or applied it but I do have a lot of media blasting experience and between that and reading up on it I can say that the size of the particles will be a significant issue using generic media blasting equipment, as will the need for scrupulous cleanliness of both the work and the blast media. Regular media blasting is not a clean process.Even shooting media in the 220 grit range creates issues with clumping and even dispersion, and even the tiniest bit of moisture in the air makes this exponentially worse...microscopically fine powders would require lab grade drying equipment at a minimum and I doubt they are using typical nozzles and delivery.Also you need to separate any base material displaced by the process from the recovered media as you go, which is less and less simple as your particle sizes get smaller...and unlike typical sandblasting you can't have any stray crap in your blast stream since it's a lubricant application rather than just a textural process. So crazy filtration/separation requirements.Add in the fact that at least some of the descriptions use a two step blasting process; one to open up the surface at a microscopic level with a similarly fine media and another to impinge the lubricant powder into that microscopically textured surface...and both materials need to be kept 100% separate with scrupulous cleaning after step 1.FWIW I found a site describing a process using a tumbler and impact media as a sort of ball mill to hammer the powder into the surface of bullets...note the detailed cleaning prep process and need to keep the media clean...also consider that the lube needs of a projectile and something like an engine bearing are vastly different.https://www.bulletcoatings.com/guide-applying-tungsten-disulfide-bullets/
>>2792630Also you need to consider consistent air flow and not just PSI when sizing equipment; 120 psi doesn't sound like much but to keep that pressure up with an open nozzle requires flowing LOTS of air which is measured in cubic feet per minute, and the demands increase exponentially as the nozzle size increases-"Working at 100 PSI, the recommended compressor sizes are: #2 1/8-inch nozzle: 20 CFM #3 3/16-inch nozzle: 45 CFM #4 1/4-inch nozzle: 81 CFM #5 5/16-inch nozzle: 137 CFM #6 3/8-inch nozzle: 196 CFM #7 7/16-inch nozzle: 254 CFM #8 1/2-inch nozzle: 338 CFMThis one will run a 1/4" nozzle->88 CFM@ 125 psiComment too long.
