So I moved into a House in Philadelphia and really need to rework eletrical circuits in this 1950's house.

However, I reviewed a DIY video just to get sense of the work involved and first thing mentioned was get a permit first. I felt okay I will do this.

Start looking into it and the cost alone explains why this house probably never has been updated.

The kicker is there's a cost to get the permit then the cost to hire someone to do the work.

What I am looking to do is re work the main panel, and set up separate smaller panels for each floor. Just the way I've experienced it on a ship.

The main panel has the HiGH amp breakers for all the smaller amp breakers down circuit at the smaller panel.

Though I figure I cannot do this I then settle for a much easier solution.

Don't touch the main panel and just pull out all the old wire add some new outlets and rewire the switches.

But even then this enters into a no go area cause I don't have "MuH LicEnceSe".

My background is Eletrical Engineering, Marine industrial Electrical systems, and I had also done a HV safety course for my Job with the FED.

How much can I get away with?

The only thing I would be unsure on is if I disconnect mains to then hook over to the new system would that be noticed by the power company?

Howdy /diy/

I know this will come across as rediculous and larpy, but hear me out regardless, please.

I'm a moderately successful individual who got buck wild lucky from 2010-2015. I inherited 2 houses from both my grandparents. I bought 1000 bitcoin with some of the money I made off selling my grandmas home. Totally forgot about it and then saw one day that it was at 700 something. Back in those days I was financially illiterate and had ZERO experience trading the markets. I watched the price fall down to 575 and I was overcome with panic and sold everything....the rest is history. Made a cool 346k AFTER taxes.

Go very depressed when I saw price at 19k. But whatever. I invested my sizable net worth in a number of good investments that paid off. I was lucky, spoiled, and put in my fare share of work to make my net worth grow.

Now I am 42, retired, and live in the forest.

I am planning on building an elaborate network of underground tunnels. I want all the entrances to be concealed on the outside, and also have concealment to other tunnels from the inside. It will be a doomsday/fortress/refuge for when things turn to shit.

But ultimately, I just really wanna make some cool tunnels. I love tunnels. They are spooky, safe, defensible, and they are AWESOME.

I dug tunnels when I was young, used to build them in straight lines then put the soil on top. Well those tunnels were no-go zones after the first rain. Then they became raccoon dens, and thus, we never went back in them again.

Now obviously I would build these tunnels to an extremely high standard. But as for now, I'm just struggling to find relevant information on how to build a good tunnel. I also want to include rooms and storage/mechanical rooms.

Any of you boys got some good tunnel info? Let me see it! Cheers.

Also, tip to help setting it without ruining a wax ring(although they are $2 or whatever so no big deal if you have to use an extra).

Mount the bolts to the flange with no wax ring and dry set the toilet. Push down on the toilet and while applying pressure to the floor, see if it rocks back and forth or not. If it’s perfectly stable, set the toilet with the wax ring and you are good. If it rocks, position shims until you have the toilet solid. Use rock hard shims, non of the soft plastic shit, and only insert enough of the shim to stabilize the toilet. You can trim off excess shim with a razor knife. Set the shims where they need to be and then reset the toilet with the wax ring. You got this.

My preference is bolts with rubber washers for each side of the tank, and nuts for under the tank and under the bowl. Feels rock solid.

As far as the closet bolt tightening goes, it’s a feel thing but in general if you’re using a nut driver, you can fee when you shouldn’t be turning any more. Crank it down a few tunes and if it feels like you can’t go any further, you’re good. Almost impossible to break anything with a nut driver unless you have gorilla strength or the flange is falling apart.

>> No.1881505

I don't think I'll need any shims. Its not a super old house that has had a ton of different renovations. Current toilet is unshimmed and the floor is linoleum, I don't think there is anything hiding underneath.

So I assume using a nut driver cuts down on the amount of force one would use vs using a wrench. I guess I would have to trim the closet bolts down to use a nut driver, correct? Bit of a stupid question, not sure if I have any nut drivers.

>> No.1881528

My nut drivers have recessed driver shafts so the bolt actually slides up inside the nut driver. You can bottom it out but it’s rare. If you don’t have a driver set I would just use a small crescent, mini channel locks, or 1/4” drive deep well socket, something light. You honestly don’t need to worry that much abo he breaking the toilet as long as you use some commons sense.

You can mimic a general rodent distress call by sucking on the fleshy part of the back of your hand between thumb and forefinger with slightly pursed lips -- I wonder if that's similar to what you're talking about with your fingers.

I don't hunt but I'm an amateur wildlife tracker and you can usually get a fox or owl to turn their head in interest that way.

>> No.1881513

That's not exactly how I do it with my fingers. I use the side of my middle finger facing my thumb, get it a little wet and suck with pursed lips at the point between my middle and forefinger, mostly on the middle finger. Long and loud at first, getting quit and slower, to mimicking a rabbit dying. They come out of their holes to see what kind of danger is happening. Your method can make the sound of a rodent pretty well though.

Hi all.

I'm about to install an attic fan, but I've got an interesting dilemma, brought to you by the "We Build Shitty Houses" team (aka, whomever built my house 23 years ago.) The conundrum is this:

There are two attic spaces, separated by a wall. One space is accessible by an attic ladder. The other space is completely unused because it's only accessible via a small (maybe 4' x 4') hole in the separating wall, apparently made by a toddler wielding a mattock. Regardless, I need both spaces to be cooled by the attic fan in order for there to be any sort of efficiency here. The attached image shows the layout of the attic, as well as the two approaches I'm considering.

My concern, described in the image, is that if I take the easy route (option 1) and install the attic fan near the power source and in the accessible space, the majority of the cool air pulled in from the other gables won't be equal. IE, the majority will come from Gable 1, and the accessible space will be cooled, whereas the less accessible space would only be marginally impacted. Thus, I'm assuming I need to take Option 2, which would be more likely to pull equally from the other two gables, cool the accessible space, and still pull the cool air through the toddler hole into the inaccessible space.

Does anyone have an opinion on this? Is option 2 the right route? Or am I overthinking this, and option 1 would work just fine?

Thanks in advance!

First off powered cable vents are no longer allowed in many areas. Check code.

Second and the reason they arent allowed is they do nothing. They certainly dont pay for themselves with conditioned air savings. And often just pull cool air from conditioned space because of cracks and gaps and insufficient insulation.

If you insist on putting a gable fan in, I doubt much air will be pulled through the other 2 gable vents because roof vents/gaps etc and soffit vents/gaps.

The radiant heat from the roof on summer daywill over come any fan. Spending money on a powered system wont change the temp and will only pull in conditioned air.

Put in a compact ladder in the other section of attic while you're there

>> No.1881270


I get what you're saying about the radiant heat. I'm considering taking the fan back and instead buying some radiant barrier and putting that up in the rafters. I think this is especially relevant as the ducts for the upstairs HVAC are all up in the attic, baking in that radiant heat.

But would I really have to worry about the fan creating enough negative pressure to actually draw cold air up from the house? Cracks and gaps in the ceiling aside, I have two huge additional holes in the attic. Those gables are almost 3' wide by 4' tall. Wouldn't it be a sort of path-of-least-resistance thing?

As for other vents, I have soffits, but the house wasn't built with ridge vents. It's something I'm going to have put in at the point that I have my roof replaced, but that's much further down the road.

What climate zone are you in? How leak tight is the duct work? Is the duct insulated? Depending on these answers a radiant barrier may make sense. Generally, climate zones 1 and 2 in the US are where you get your money back in radiant barrier. If you have tight duct work that's insulated, the radiant barrier probably won't make much difference. If the duct work is leaky, the radiant barrier would be much more effective than a powered attic fan.

>> No.1881446

I honestly would just consider rolling out more insulation on the floor of the attic first, always do the easiest fix first

Their grips are still my favorite of any brand of pliers. I have no clue what they use, but they have the best combination of a little sticky and soft but not that shit that gets tacky after a little oil and they’re comfy without being all fat like some comfort grips.

The marvel of 442 and 440 channellocks is their ability to have their handles so close together. It gives a great opportunity to really grip onto the fastener; pipe or so on. Knipex pliers are great; I have a pair of 12 inchers myself, but their handles don't close as far. They sacrifice the handle so that it can be shorter and the jaws can open much further. But when you're working to really grip onto something, you want to have as much leverage as you can. We use compression fittings at work where you really have to tighten each coupling/connector (takes more time to install compared to set screw)

I don't bother to carry them my pair of 12 inch knipex alligators to work because those pliers will walk off. It's not that the equivalent knipex costs more; the alligators (which lack the button), cost as much as regular channellocks. Meanwhile; 442 is exceptional for pipe work.

I cut the tips of my plastic handle off, just when they bend inwards on my channellocks. That shit is what I use to knock out Raco's 4s boxes with. Way better than needle nose; which I've also lost as well. I can also use them to ream my conduit with. People talk about using their linesman as their hammer, but I believe the 442 or 440 channellocks weights slightly more. I've yet to do a full measurement. I knock with either the ends of the handles (which have the exposed tip) or the back of pliers.
