Neighbors keep smoking downstairs and they won't stop, trust me I've tried everything. And the landlord won't make them stop and the authorities won't make them stop because the city I live in is like a third world country. I need to filter the air. It comes from the vents and cracks around the edges of the floor. What do I do? Please help. I do intend to move but it will be a while before I can.

>>1594182
I'm guessing he means most of the other 60% is caused by things outside of your control, like spreading bushfires. Though I'll admit including bushfires would skew the average a lot. Either way it says nothing about the absolute chance that your house burns down for any reason, which is probably a more useful statistic in this case.

>>1594309
From what I've seen on /diy/ the other 59% if that is electrical fires and the other 1% might be wildfires if you live somewhere liable to catch fire.

Well if you're building a new home you don't have to worry much about electrical fires either, because your wiring will be up to code. I imagine it's mostly older homes that fall to that.

So I have a small project going on /diy/

I'm basically going to make a 60A 1p 250v power hook up point like for an RV, but for a Shipping container or other large equipment to run in my yard. But mostly for the container, because if it just plugs in, it's portable equipment and doesnt need any bullshit codes.

So my current plan is to run out the house distribution panel, down, under the house and out the back through conduit, then buried conduit for 15ft or so over to where it will come up against a post to the box and plug next to the container.
I currently have almost enough quadplex either 2/0 or 1/0 Aluminum with a bare ground.
I'll have to make a splice point under the house somewhere and run more wire, but there is a large watertight box where all the power splits off down there already.
I also bought a socket and plug 60A pin and sleeve. 460P9W and 460R9W.
I also have some SO cord laying around that may be 4/4 but if not, I'll pick up 15ft of that.

I'm just not sure what I should do for the plug box out back, if I need a switch, and what enclosure I should use. I'm also not sure if kernies wrapped in tape is the most ideal connection method for 2/0 in an enclosed distribution box, but they've been doing fine on house drops for a hundred years or so.

Other then that, does this all sound mostly correct and not housefirey? Anything else I should do? Any tips?

Mostly because I got a good deal on the 60a plugs, but also because of some of the equipment I want in the future requires 60A. I was going to run 100, but I was looking at $250 for a plug and socket instead of just $100

>liquid tight the last meter
This is what I'll probably do,
Either that or put a street 45 out of the top of the back box and bend some pvc into a 135. I need to watch my cable length though because I only have so much quadplex.
Found it laying next to the street one day, so I rolled it up and took it.

>>1595007
Nominal is a desired voltage. But when you load it down the resistance of the windings start to pinch the voltage (among other things). So substations use auto tappers to adjust and try to maintain the "nominal" voltage. Pf correction also changes this. Utilities try to stay within +/- 3-5% of nominal.
But there is nothing constant about utility signals. The voltage and frequency drifts with network load, synchronization, pf correction, filtering, etc. It's why 240v plugs are rated 250 and everyone measures "around nominal".
If you share a can with your neighbour measure both hots of your panel while the wife and the neighbours wife are both running the stove and the dryer. In some places it'll drop around 110 or less. For those with monster power bars it's annoying af because it cuts out the load on undervoltage. In large a metropolis the street bricks can pound alot more amps so they don't notice the drop as much.

If you go with the 135 choose a wise position for a cleanout or 2 or you'll be sorry.

I'm looking at a house, but when checking it out it seemed they used plywood in some rooms instead of sheetrock.

It's older from 1976. When I viewed it they were in the process of moving out and it seemed like they are selling due to medical issues. It also seems like someone there had a mental illness (dramatic post it notes on DVD cases from ex lovers, KISS style platform shoes next to the their gym equipment, holes in wall from punches also lots of sport related injury braces and neck collars)

Also one room had a wall with plywood and a small gap they used spray foam to seal the gap.

This house has a massive yard compared to the area along with 3500 sqft.

What sucks is I live out of state and can't go check it out that often. the wood around some windows was rotted and can be knocked away with little force

Ideally you want your lead screw to be in tension broheim, get some alu extrusions.
>>
>>1594862
>lead screw with a "1/2" diameter be sturdy enough

Kind of irrelevant for a 3D printer. No weight and no forces at all. Half inch could handle several hundred kg. The only problem with tiny leadscrews would be vibration if you use small screws with high rpm. I used a printer (~500mm) today with 4mm screws because it's older than the chinesium 8mm standard screws. Use whatever you can get for the least amount of money. Big screws add a lot of intertia which limits your acceleration unless you use bigger motors.

Ur funny. I'm a fucking engineer. I work with the girls on the tools. I don't just send them off to a job blind all the time I design it, buy the parts and show them how to build it. Believe me after watching those chicks like a hawk for years I have nothing but confidence in them. If they need a screw it gets charged to a work order I have to answer to and I've yet to see them run over 1%! But then they are a good fit for the job. I can show you female engineers who use their tits for promotions but aren't worth a damn and that *is* cancer. Last one we fired fucked up 3 million cause she can't use excel.

>>1594924
>google
>be honest

OK I will. If google was 95% male it wouldn't make a lick of fucking difference because even guys act like sjws with a political agenda and that's the problem with jewgle, not gender. The affirmative feminist/immigrant/native/lgbtq/everyone's equal action forseen upon the land has given an avenue to these jaded, antisocial people with a chip on their shoulder, to become the cancer you describe.
Microsoft is a male dominated company and look how metro /Windows 8 came out, or the massive bullshit that is win10, the crazy 180 with Linux... Those sjws failed hard by pushing political leftist shit onto the masses and it ain't stopping even when fur (or bullets) fly. Instead it pushes them harder.

So I don't think the problem is women. Its people with the bad agendas, groups whom starve for control, power, and inclusion, no matter the cost, under the guise of being progressive or social justice oriented or cause its 2019. You and I have every reason to be raged about this because it is a cancer, but gender and equality is only a smoke screen. It's just bad ideas by angry people whom acquired a touch of power but think their shit don't stink and that their opinions mean something.

Some time ago I tried an experiment, to see if my regular office chair with generic tilt control would feel better if I locked it at a permanent 110-120ish degree angle, so I stuck a couple bolts in the mechanism, went full retard with hot glue to keep them in place, and for a while it worked and it totally feels way better than having the chair at 90°. Due to the nature of the mechanism the bolts are eventually prone to slip out, not immediately though (last time took weeks).
Do you think there's any way to make this system permanent?
>can't you just lock it?
No, usually reclining chairs are fully designed for that, with generic chairs you can only lock them in place, tilt them without locking them, and adjust the amount of tilt you want.

>>
>>1591018
You can also try cutting a notch in the side plate so the bolt doesn't want to slip out, but then you may have to go up a bolt size to get the same height.
>>
>>1591018
if you have even a rudimentary system of drilling you can place a second hole for the tilt lock at the desired position.

Cut out a wooden wedge and glue it in place. Sould be sufficient for this application.

Use this instead of hot glue. They'll never come out again.

Seconding this, use a generous amount and it will be permanent
