I'm renovating an old house, one of the rooms had wooden deck flooring that was in a pretty shitty condition.

Removed the decks, beneath them is a layer of fine sand and underneath it a thick layer of soil (under the soil is the concrete foundation).
The soil is pretty dense.

My plan was to first remove the top sand and add a layer of gravel (2-3 mm thick).
Then add a nylon sheeting, a wire mesh and on top of that pour concrete 7-8mm thicc.

When it dries up, put a coat of liquid hydroisolation shit then a foil and laminate flooring.

Does anyone have experience with a concrete floor?
Any tips?

dowel into the perimeter bricks with rebar too. though, i'm not sure those bricks are sturdy enough. use plenty of rebar and mesh. tie it all together. make sure the mesh isn't just laying flat on the ground (use little dobie blocks).

Bought a house, and one faucet has black specks coming out of it. I wiped up some on a rag from a clean glass, and a few days later the rag is dried and I check it. The rag smells sort of metallic, like iron or coins. The specks are either solid or they smear, leaving a black streak across the rag. Some of them appear to be slightly magnetic, as I rubbed a stud finder against the rag and some stuck to it,but that might just be false alarm.

I don't know much about plumbing; Could anyone help me to identify what this stuff is and where it is coming from? I have checked the other faucets, and none of them are producing the same specks. This sink is also a black metal fixture, with braided metal going through it (the head of the faucet can be pulled out and directed by hand). My guess is to look in the braided hose running up to the faucet head, but I am not sure what I would be looking for or how exactly to test it. Insights from knowledgeable anons is appreciated. Thank you.

Do any anons here have experience with fixing up old sailboats?

Due to personal reasons living on a sailboat has become a desired goal and i have been working on sorting out the details and steps neccessary to do so. However most of the guides and books worth reading on this subject are hard to find because the market is flooded, it's all behind a paywall and whenever you google something a shitty youtube video pops up. So i am looking for resources you'd reccomend and any tips sailing anons might have.

So far i have decided on a second hand 28-35ft boat capable of ocean crossing, there is plenty of older 30-40 year old boats available but i am worried about the hull condition and am unsure what to look out for.

Work at a marina and learn how to fix everything then you'll be an informed consumer (or hate boating, but the experience is useful). You'll learn better and much faster doing it commercially like any other mechanical and structural work.

As with any vehicle those who know the most are those who fix and maintain them, not those who merely buy them.
>>
I'm a lifelong sailor currently restoring, racing, and cruising 45 year old 30 foot boat. Ask me anything specific.

>>2233802
Is the way to go if you're starting from zero. There is a lot to learn. Learn to sail, crew with other people before buying your own boat. Maybe start with a 10-15 foot dinghy first. Or I guess you can jump right into owning a big keelboat but you will have to accept more expensive and scary fuckups if you don't go in with a little prexisting knowlege.

For specific jobs https://marinehowto.com/ is great. A lot of the sailing/boating forums have been around for years and are full of excellent information if you search.

People have been restoring and cruising boats for thousands of years so there is an huge knowledge base out there. But that also means there are right and wrong ways to do everything. Generally DON'T HALF ASS SHIT. The sea is unforgiving, whenever possible, do it right the first time. Shit is expensive. Boats can be had cheap, but storing and maintaining them will cost more than you think. Like, if you want to restore your old shitty project boat and keep it in acceptably good/safe/seaworthy/maybe even fast condition, and stored somewhere easily accessible, you're likely looking at $10k/year in parts, upgrades, marina fees, and consumables. This is still WAY cheaper than what people spend on "nice" boats and if you use the thing it can be totally worth it. But boats ARE expensive.

Now is kind of a bad time to buy a boat, prices are very inflated since everyone bought used boats during as pandemic projects. If you can wait a year or two the bubble will probably burst and the market will be flooded with excellent options.

not sure if this is the right place for this but i think antique tools is /diy/ related. i found these two ring things in a box of old stuff from my grandparents shop. i think they’ve got something to do with Leatherwork or a Ferrier since grandpa like to collect those types of things. can anyone help?

Leatherwise, the only thing I can think of is an inskirt rigging ring for a saddle. Wrought iron seems like a terrible choice for saddle hardware though. Whatever it is seems like a poor design anyway, the least retarded use for that object I can think of is to screw into the end of a pole.

Weedkiller is essentially roundup. You need to buy genetically modified grass that will survive roundup.

A lot of people don't seem to know that genetically engineered crops are modified for one thing only: to survive roundup.

Not that there's roundup on your lawn, nothing will ever grow unless it's genetically engineered grass sold by Monsanto.
>>
>>2234789
>hasn't heard of selective herbicide
>doesn't understand genetic engineering
Not all weedkillers are glyphosate anon. Folks who spray lawns use something like MCPA which is broadleaf specific, as in it'll soak into the big fat leaves of thistles etc but not harm grass. There's some interesting science behind it worth a read. Even if it was roundup, it's not barren forever you fool

You're just as retarded. If you knew anything about engineering, you would know that Fe2O3 deposits are very porous and potentially flakey, which entraps air and water, even when the rod is seemingly surrounded by concrete. A tiny bit of oxygen is all it takes to further rust the steel and create new routes for oxygen along the surface of the rebar and the rusting process continues. Clean rebar won't trap air on its surface as the concrete is poured, so it won't rust as quickly.

Also vibrating the surrounding concrete thoroughly is probably more important for preventing future rust.

>you dont even need rebar in a foundation if you have a floor system
This is unbelievably dumb. Floor structures are never designed to take that sort of shear force, but that's not the point. Rebar spreads the load so that transverse point loads or varying UDLs don't split the slab. And have you ever heard of reactive soils?
>>
>>2233330
Little bit of rust is fine. It may be even better as some suggest. Gl hf
>>
>>2234605
This sounds very logical from a chemical point of view.

One question, how do you explain that all rebar seems to rust to some degree if this is standard practice?

I found this in the basement of the place I just moved into. I brought it to the attention of the homeowner so I'm hoping to hear back from them about how they're going to address it.

But I'm posting this thread because I wanted to hear from you guys, what should I look for in terms of the job that they do to make sure it's done right in terms of removal and prevention of new growth?

My mum has a bladder rainwater tank under her deck. It's a terrible system, but not my choice unfortunately. As part of various stormwater upgrades, I need to replace the inlet to the tank. This is a standard uPVC part which is glued to the (reinforced) vinyl of the bladder and secured with a hose clamp. I'm not sure what adhesive I should use to bond the the bladder to the uPVC socket.

Is ordinary solvent cement for PVC pipes okay, since the bladder is presumably some sort of PVC (not uPVC though)? The manufacturer provided me with a small quantity of repair adhesive for patches, with no datasheet but a warning that it contains cyclohexanone and xylene. The pipe cements I've seen contain MEK and cyclohexanone but not xylene.

Pic related is the inlet on another one of these tanks (not installed yet).

I will, but this thing holds 5000 litres of water and that inlet has quite a lot of pressure when the tank is full, so it needs glue as well.

My girlfriend bought a plain lamp with no wiring and she asked me to wire it. I bought a lamp kit at Lowes but the problem is that the standard male threaded 1/4 ips "nipple" that connects the lamp socket to the lamp body does not fit into the female threaded 3/8 ips of the lamp body. There is hardware, called "reducers" that can reduced 3/8 ips to 1/4 ips but it would cost me like 10 dollars to ship for a piece of hardware that costs $1.

My question is can I used standard plumbing reducers, or do I need to stick with "ips"?

if those parts are live to begin with something is seriously messed up, you shouldn't need to insulate the top of the lamp from the bottom like that. the only place there's any current is inside the wires and the interior of the bulb socket, both of which are far away from the part OP is talking about

I know this sounds like an extremely stupid question, but I'm ignorant and I want to learn. No matter how much I Google, I can't find information on if a laptop motherboard should heat up when connected to the charger when it's out of the laptop.

I just replaced the charging port of a Lenovo laptop here (first time doing this kind of repair), and I decided to try if it was working, so I plugged in the charger and the battery to the board, and the charging LED lights up. I don't see any sparks or smoke, so I assume it went smoothly.

However, the GPU and the chipset heat up for some reason, even though the laptop is off (I haven't assembled it or anything, just plugged in the charger and the battery for this quick test). Is this normal, or I dun goofed? Does it go away if I assemble the laptop?

It's a Lenovo Y540, one of those with a 230W charger.
