Can I use discarded street stones as bricks to build up walls? Or is there something about them that make them improper for that usage and only good for flooring?
>>2890864Or you could put rigid insulation against the block wall, and run whatever utilities in that, like in ICF houses
>>2891066It's not uncommon.I think brick is overrated as an exterior cladding material, at least in northern climates, since the mortar erodes with freeze-thaw cycles and needs to be re-pointed.
>>2891165Thats why the cement block is supposed to go well above ground level
>>2890380>because americans are too stupid to build a wall straightchecks out
>>2891066i like the mesh holdy system, anyone used it before?
I made a spoon, fork and spatula in juniper wood (pic not mine).For the finish I sanded them by hand with 200 grit sandpaper, they came out pretty smooth, but then I washed them and the water made the wood fibers stand back up and out.Is there a way to get a smooth result that stays smooth after contact with water ?
finer sandpaper, then coat with beeswax
>>2890611>>2891083just use tung oil, wipe on a few coats and let it air dry and polymerize
finish of any kind on cooking utensil is disgusting
>>2890612>>2890809These are correct. The grain is going to raise when wood gets wet. Period. If you want it smooth after it gets wet you have to sand again, then again, possibly a fourth time as well. Scraping works better than sanding, but will still probably take a repetition. This is basic woodworking stuff, sad that so few seem to know about it here now.
the key is to cut the finish rather than abrade, scrapers and special knives are made for this.
Picrel: Lego Minifigure head storage (small)Storage seems made of polyethyleneGap's about 5mm wide, 15mm deep; central part is about 15mm higher than the outer bottom of the box.Was thinking using hot glue, but it's a tricky location, and temp might melt storage box plastic.Silicone probably wouldn't last long.Hoping to achieve a smooth non porous surface.
>>2888557Cover it around with tape.
>>2888993>small parts get stuck thereTake a piece of cord (cotton rope, whatever), cut it to the circumference of the gap and pack it in.
>>2889798I want something that lasts; foams/anything porous won't make it.>>2889845Center part is about 1.5cm higher than the outer part>>2890705Not really what I'm looking for, but thanks anyway
>>2888557I had this exact problem with the brick shaped containers. Just tape over it, it's held for years now without issues.
>>2891219Like I've said, this box has the central part higher than the outer one by some 1.5 cm; it's not like the brick boxes.
I'm thinking of becoming a tradie. How is it as a career and how difficult is it on your body?
>>2891114I don't know
>>2891114There's no way of knowing
>>2891114>How is it as a careerDepends on where you work. Climate, people, etc. >Will it fuck your jointsProbably. Depends on your willingness to use safety and health equipment, and the field. Working on plumbing under a floor is going to be worse than hanging drywall standing up, unless you take certain precautions
The sheer amount of people who dismiss earplugs just because they tried it a few times without actually knowing how to put them in is staggering. They are just doing it wrong (just like the pic).I just love the feeling when they slowly expand inside your ear and just like that - all the sound is completely quiet!
>>2888187>immediately mentions vaxthere were studies done, proving that being exposed to loud noises for far too long reduces IQ, and now, I have first hand experience of it being true
>>2886035i dismiss them because they are gay
>>2889350takes one to know one
>>2886920Wind noise is something else, it's just the fact that you're sitting there exposed to 80+mph wind as you're going down the highway, it's a persistent loud roar. It is definitely the main contributor to my own tinnitus, an occasional gunshot-without-earpro or a concert are certainly tiny chips of damage, but an hour a day for years of loud roaring noise when commuting catches up to you quick.Loud pipes aren't even as loud to the person on the bike, it's significantly worse to be next to someone with loud pipes than be riding something with loud pipes, like it is physically painful to be riding next to a straight piped two stroke.
i love ear plugs. when i pull them out they are caked in wax. i like to eat it off the plugs.
I want to build a drill press for shits and giggles, me still not owning one and hopefully turning into a soft mill later on.So far i got a working 3d printer, rods, nuts, concrete, all the boring parts and pic rel in 750W version. Just ordered linear rails for Z. However i'm really starting to struggle with english here. How do i get a drill chuck on there, as in, what parts am i missing and what are they called? I thought the motor would be the spindle when doing a direct drive, but the spindle is just a mount? And when looking for something like a drill chuck adapter, google greets with a plethora of morse tapers, which is great i guess?Given that even chatgpt can't grasp what i want to do, i'd appreciate some help on the necessary vocabulary.
>>2890662>>2890664It's a 750W AC servo. I'm sure it'll do fine and if not, i'll throw in a planetary (or rebuilt the whole into aforementioned lathe). Sorry for the tiny picture, i was only slightly frustrated when opening the thread.
>>2890583Will the motor bearings take the axial load? Many do not. And that's why the motor drives a spindle with a belt. Spindle has bearings and an advance mechanism designed to take the load.
>>2890582Just cast some iron in your moms backyard Then scrape your box ways flat If mori seiki can do it so can a neck beard with a 3d printer
>>2890582If you go on eBay, you can buy fanuc motors, fanuc drives and a fanuc controller for pretty cheap And if you call fanuc and ask for tech support from their Cnc department they give free advice You can build your own mill or lathe using their controls especially with the kits from eBay where they have the frame, ball screws, linear rails and z axis assemblies

What is the best option? Im thinking butcher block. if butcher block, what's the best epoxy to seal it with? I've used tung oil in the past for stuff like this but it's a real process to get saturated. >OMG you can't put hot pots on wood counters! Trivets have existed forever and I'm putting a 6 burner range in, I think I'll be ok.
Has anyone done pour in place concrete? What did you use? Any regrets? Any tips?
>>2890812I wouldn’t go with oil. Yes bars exist but oiled wood (‘uncoated’) bars are from times before acidic cleaning agents, you’ll remove the oil finish whenever you spill dish soap or tomato paste or put oxalic acid cleaner to remove a stain. Which basically means you have to oil it after almost every use in the first year until the oil completely saturates the wood. And in fact bar/inn keepers would do this after every shift (rub the bar before closing)
What's wrong with Formica? Durable, piss easy to clean, requires no actual maintenance, soft enough to reduce its impact on knives and glassware, and a white surface will instantly telegraph if you need to clean the counter or have had a spill
>>2891018>pour in place concrete?My brother did. Turned out nice. But getting there was a mess.> pour> let set> several steps of sanding/polishing that were just messyI asked him if he'd do it again. His response: "fuck no"
>>2891130Yeah idk I think my best idea is just do plywood temporarily and figure out my layout and then get granite/quartzite. I'm likely going to build my own cabinets and buy doors because I want 42 inch height bc I'm 6'4 and I'll just use the cost savings for stone
I can't find an answear to my issue anywhere.both of my earphone cables got fucked up so i decided to basically connect 2 diffrent cables together to somehow keep them alive, cables are both 2 pin 0.78 but WHY THE FUCK ONE GOT 4 WIRES AND ANOTHER GOT 2Im going fucking ape shit rn, i already cut the cables and wtf do i do now. Ohhh and i plan on just twisting right wires together and covering them with some silicone i found. Please help me, i definitely cant afford newer ones:C
I'm assuming there are two audio channels, a ground and another wire for some kind of control button or other additional feature. That's what I've found repairing my own headphones.
who cares how many wires there are, just connected them how you need.I googled 2 pin 0.78 and you can find it's a cable that has 2 channels. just solder the ends together if you only need 1 channel.
>>2889703>I can't find an answear to my issue anywherewhat a dummythe answer is right in front of your faceyou just connect wires in sequence until it works as good as it canwith only 6 wires, there are just a few combinations so you can try them all in 3 minutes
>>2889765Don’t do this OP. You’ll electrocute your ears and never hear again.
>>2889703There are three standard types of headphone wires:TS: a mono audio line and ground lineTRS:left audio, right audio and ground lineTRRS: A left audio, right audio, ground and microphone line.
Are there any books, online tutorials, etc., that talk about how to build structures that'll last for a long time? Going into detail about what is the best kind of stone and brick to use, the fundamentals of building a roof that won't collapse with mere time, the right kind of wood and how to treat it to prevent decay, so that the structure will be livable for centuries afterward and won't come down barring human interference?
>>2890986I guess start with where you want to build first, the type of environment, then work from there.Or just start with learning masonry. You're talking multiple skills over a vast number of specific trades.The thing is, you don't learn any trade through a book, but by actually doing it. If I could read and memorize every book on auto mechanics....I'm not a mechanic until I actually get under the hood.
>>2890986>build structures that'll last for a long timeDepends on how long. I don't think concrete foundations will last longer than old school mas stone ones, because rebar will eventually always rust and become powdered iron, then you have a problem once the first earthquake hits. You're still looking at hundreds of years potentially though.>what is the best kind of stone and brick to useWhatever is locally available, provided that the stone is not too soft. Worked pretty well historically.>the fundamentals of building a roof that won't collapse with mere timeImpossible. But ventilation definitely helps mitigate rot and whatnot at least. The roof on my village house has stood for over a century now.>the right kind of wood and how to treat it to prevent decayAlways oak, everything else is a meme. Especially pine. Wood's resistance to rot is dictated by it's density and lignin content. Oak and chestnut win n both categories,. everything else is just plainly inferior. Density = structural strength too, but that's less relevant because you can build a strong frame, floor or roof structure with pine just as well. Can't expect it to last as long, however.
I'm making various body armors. Here is my current setup:Torin Gray Porcelain TileSingle layer of 18oz fiberglassTorin Gray Porcelain TileSingle layer of 18oz fiberglass24 layers of 18oz fiberglassAll surrounded in 2 layers of 18oz fiberglass and cemented with 1 layer of 18oz fiberglass.It survived 10 rounds of M855 from a 20" barrel at ~30 yards.
>>2891032Anyway, the point of it was not just its effectivity, but its simplicity and easy of diy. It was just a matter of laying some 3 layers of tightly packed small steel balls in a mould, then pouring the pe plastic, or vice versa. It was pretty much just this. I think it also mentioned cylinder (magnets like) shaped steel, but that's pretty much just all about it.
>>2891032I think the patent was by some Israeli. It was from 8ch pol (dark grey background theme. That I definitely remember lol).
>>2881384One method for DIY body armor I've been curious about for some time is using epoxy resin with glass fibers mixed in and suspending steel or ceramic balls in the mixture. The only down side is high quality epoxy can get somewhat expensive but maybe the glass fiber filler and steel / ceramic balls would displace enough volume that it wouldn't take a large amount of epoxy to form a plate. Another downside would be making it curved. If you pour the epoxy in the mold with the backside of the plate laying down, the front of the plate will become flat and only the back of the plate will be curved. You could make the mold so the bottom of the plate is pointed downward which would allow both the front and back to be curved but then you are doing a deep pour and have to worry about bubbles.
>>2881408The problem with steel based armor is the bullets tend to fragment and create a bunch of spawling that can be dangerous. The plates need to be encased in something to capture the fragments but I've haven't seen many commercial steel plates that do a good job of this. I recall seeing one steel plate that handled capturing the spawl pretty well and used a type of polymer coating to mitigate the fragments. But that plate cost almost as much as many ceramic plates so that kind of defeat the point.

Apparently Japanese people have these in every house. How hard would it be to attacha small electric waterpump (like 50 kW?) to the water supply line and then just run a pipe under the toilet seat? Self ass cleaning toilet would be neat.
>>2889610You know you're not supposed to "shit" in the bidet... right?The toilet won't hurt you...
>>2889625You tell me this now?!?Jk, it's just one of those attachments. I like it, but my balls seem to be right in the cross hairs for how i normally sit. Also, i fucked up and accidentally shot toilet water at me. Needed to take another quick shower.
>>2889617they aren't cheaps and add to yearly expense and wastea bidet will reduce yearly costs and produce less waste
>>2889557It's a tank from an old water heater. 40 gallons, not 80 (my mistake). The tank has had the insulation & wiring cut off / heating elements removed / holes plugged and is run directly from the well to the bathrooms, so it's potable water. I couldn't remember if it was inspiration, tinkering, or just not wanting to throw away a broken water heater as this was all done 20 years ago but it solved the moisture issue so I'm happy.
>>2887853>ike 50 kWbro you're going to die but most likely the electric safety should trigger if you try to draw that kind of powerlawn mowers are an order of magnitude lower in power demand and the rule here is that 10KW is enough to heat a house during peak wintersurely you meant watts?not the first time i've seen this mistake and the other day i came across watts an hour. i guess it has a meaning but most likely not what the authors intended
this wood was absolute junk. some of it is on it's 3rd recycle use. the vertical supports were from a single, severely split & slightly rotted 2x8. the shelves are a recombination of leftovers from the shelving, trim & finish work from our house construction. about half of the screws were reclaimed as well. the red/white checkered cabinets were removed from a remodel job. we installed them 2 weeks ago. had to do a little Welshman's engineering to move the electrical outlet over 3cm. extremely sturdy, able to stand on them. I "stair stepped" the corner shelves for maximum storage surface area.Part of the wife's Solstice gifts. I will definitely see booba.
>>2889942theres been a few gooseneck trailer deals ive regretted passing on but i dont need that much deck often enough to justify storing something that big. goosenecks do tow and back so much nicer thoughi really want to upgrade my tilt trailer to a split deck 14k but most are lomger than a whores dream. nobody really makes a 14+4 split tilt. plus even though it hurts to pay the rental house, it honestly pencils out about cheaper to rent a specialty trailer for $125 the day i need it rate than tie $10k up in one
>>2889921where is here?
>>2889942this is ridiculous feel like that telehandler should be hauling the pickup and it should just pick it up and place it on the trailer
>>2890158>this is ridiculous feel like that telehandler should be hauling the pickup and it should just pick it up and place it on the trailerIt would be right at the lifting capacity, but it could probably lift the pickup. Lol. Main reason i hauled vs roading it home was because I had to go through a somewhat populated city to get it home... Very next week I roaded a sprayer home at 17mph for close to 60 miles. That was way more rural and less traffic though. Also would have been tall and awkward to load on a trailer.

Hey /diy/, My current job involves a lot of designing and building control systems for machines, something I came into the job knowing nothing about. I've done a pretty good job of getting up to speed, but I'm constantly finding out about better solutions and hardware and best practices that I wasn't aware of. Given that I have no formal education in automation, does anybody know of any good resources for learning more about the hardware side of things? I'd like to step my game up. Picrel, a cabinet I designed for one of our machines.

Building an ICS and OT network from scratch using VRF-Lite for a +200 skid manaufacturer, 0 to 80 done in six months. I'm a department of one for all office and dirty work, and have been for nearly 3 years. I'm also the GMRS guy, the surveillance guy, the desktop programmer guy, the CAD guy, the aerial lift guy. I dedicated myself to learning and honing these skills to be better than anyone else in the room. Finally passed 30 a few months ago.I'll be debt free in 2.5 years and a father. I'll own a wooded plot and cabin in 3. I'll replace this 98 Corolla in 5, God willing, with a 2008 Corolla or whatever is a good deal at the time. After that, who knows.
>>2875731>there was some guideline document for cabinet layouts (I think by Allen Bradley) that’s widely used but as far as I know never became a standardIs it this? https://literature.rockwellautomation.com/idc/groups/literature/documents/td/1711-td001_-en-p.pdf
To address contemporary needs of the contemporary Anon, I wrote a sequel to the critically acclaimed "solarshit" guide. I present to you: heatshit. https://rentry.co/heatshitIt mostly focuses on how not to fuck up heat pump installs, but all the principles apply to condensation boilers, too. Also explains some basics about central heating components, so it might be useful just to learn what various parts are doing, or not doing in your system, even if you have no interest in heat pumps.
>>2886331Yeah, you put 4, 8, or 16 of them in series. Ready-made LFP packs are considerably more expensive, hence /diy/.
>>2885731What the fuck? Are those that cheap these days? Just around 200 € for a approx 12 V setup, nice!
>>2887090Prices have dropped massively in the last 2-3 years. You do have to give it a BMS, that's another $50-ish for a 12V pack, plus wiring and fuses, but still. Or you can get A-grade cells for $60/kWh.The ultra budget chang drop-in batteries are also pretty cheap, you can get a 3.5kW 12V one for about $500, but they are much more mystery meat than buying these cells, and it's still over twice the cost when building a big 48V battery.
>>2885309There are YouTube vids of that reflective material sealed onto a frame and vacuumed.Those mirrors are far superior.
>>2884207Final-ish version achieved. As it turns out, putting a bypass around the UFH pump was totally pointless since the pump is non-blocking to relatively low flow speeds (expecting up to 6L/min there).More or less settled on the heat pump, a 9kW LG Therma V monobloc, will be ordering it probably next week, after I get this distribution manifold hooked up. The 9kW is oversized a bit since our target heat loss is around 7kW-ish, but I've seen some numbers suggest on the Therma V that the same physical size models probably have the same kW low-end modulation and only their peak power is different, plus for weird market reasons the 9kW model is cheaper than the 5 or 7kW models. Also probably won't have warranty coverage since /diy/ install, but fuck warranty when you can buy a whole another heat pump for what it'd cost to buy from an authorized dealer and get it installed and configured by authorized servicemen.
