Fortification and trap building

>>29812741
>Trap building
Two words: Hormone Therapy

On a serious note, a lot of houses have built in shelters and there are companies that will build bunkers for a price. As for less expensive means, just get sandbags and the same steel they use to make targets and do what you can with that.

>>29812794
That gave me a good laugh thanks

>>29812741
on a related note, would it be possible to make fortifications out of something like Quikrete?

If anyone uploads the do/k/ument there's a fair amount of information on trap making in there. For fortifications it shouldn't be too hard to find old military manuals online, and at its most basic it's hard to go wrong with "dig a hole and put shit in front of it. Pic somewhat related.

>>29812741
Also what sort of setting are you in? Urban, woodland? I have some old documents about OIBUA

Yes, the info exists. No, I don't know if it'll get you on some list. If this thread is still up when I get home from work I'll post some titles I have. I think most are out there as scanned PDFs.

>>29814907
>>29814442
That's fucking nasty looking simple but brilliant. My only question is would the bolt actually function like a firing pin?

>>29815913
I guess it depends how much pressure is applied and how quickly.

Personally I like a design I saw at one point of a shotgun shell rigged to a mousetrap and tripwire. Trigger the tripwire, the mouse trap activates smelling a bolt into the firing pin. Best part is that you can run the wire so the shell is at head height if required.

I like pic related but with an outer wall, basement bunker with underground shooting range hallway/escape tunnel.
The ground floor should be a garage/workspace.

>>29815913
Yes, this would work. It´s pretty much like a slamfire shotgun. You don´t need that much force to trigger the primer

a common method of fortification if you can't afford a true caste was the tower house. I'm sure you could update the concept a bit to withstand small arms, and make it a bitch to attack with larger weapons.

The plans for my property are currently being drawn up.

>Two acre plot.
> nice victorian house (no fortress)
> Basement lined to protect against EMP with enough space fir 8 bunks as well as food and water supplies.
> Two entrances into basement one inside house, one 100 ft away
> whole property going to be walled in and backed by a berm reinforcing it.
> rainwater collection is going to provide water as well as two wells on the property.
> space to start farming, fruits, vegetables, small animals, bees.
> there will be a few trees on the property but they will be taken down in a SHTF scenareo to clear line of sight.

If SHTF I'm gathering together a team of trusted friends and family to move in and live here.

I have Topo maps and aerial photos of most of the surrounding areas.

Should we need to i am planning on bulk buying sandbags, we will dig a trench system into the berms to allow movement and fire positions as well as bunkers on the corners using the mud we dig to fill sandbags.

Check out insulated concrete forms. Several bags of quikrete along with a cement mixer from harbor freight gets you solid monolithic concrete barriers anywhere from 4"-12" thick with little skill and minimal time.

If you never served but someday want to build cool SANDBAG BUNKERS someday then remember:

There's a castle in Wexford, PA (just outside of Pittsburgh) that was built as a residence for a couple of wealthy Society for Creative Anachronism nerds (a head and neck radiologist married to a child psychiatrist). It's kind of neat, but not quite /k/ prepper-tier.

Would you not also need a mold and some way of moving your now monolithic concrete blocks?

ICFs stack together like Legos. You put the forms together where you want the wall and pour it there.

>>29819876

8 inches of concrete requires an average of 30-35 rounds of concentrated fire from an M16 to penetrate.

>>29820035
A .50 bmg can do it in one, a 7.62x51mm can do it in 10, that's from army field manuals

If you have a concrete wall less than 10" thick between you and someone with belt fed fury you cave concealment, not cover.

>>29817019

>someone drops a bomb on your shit

>>29817019
Fortifications are virtually useless without the manpower to secure them. All these paranoid prepper fags building their mini forts out in the woods would get reckt y even the most mediocre band of misfit bandits.

>>29820169
People forget that cannons killed castles. And they also forget mortars and simple rockets aren't stupid hard to fabricate ie IRA, SYRIA, ETC....

>>29820309
Hell even lathing out a cannon from bar stock isn't hard anymore. Also it's legal and counts as a black powder weapon so no taxstamp...

>>29819876
Can you make the walls whatever thickness you want?

12" thick concrete walls with stone masonry for the base with a little log cabin on top like >>29816719 but built on a budget would be cool as fuck. I wonder how much it would cost.

>>29816159
>$150-200
Yeah in fucking 1959.

Considering cinder blocks are at their lowest $1.99 each, rebar is a quarter a foot and you need it every ~6", and a 12x12x7' shelter (without the blast baffle) would take 380 cinder blocks, ~700 feet of rebar, 11 bags of mortar, 1.7 tons of sand, 7 cubic yards of concrete....

>>29817427
>Electronic spare parts shelter


Can you post more pictures? How much did it cost you?

>>29820520
Still a one paycheck job, good point though.

>>29820563
One paycheck job?

Maybe if you mean "this will use about what I get paid" not "I can pay for it with what's left over from one paycheck after I pay all my normal month to month shit", but you're still looking at about $2500-3000 depending on design.
>minimum of $760 in cinderblock
>minimum of $620 in concrete
>minimum of $175 in rebar
>around $100 in mortar
>however much roughly a cubic yard of sand costs, probably at least $100 delivered
>tool rental or purchase (I know you don't have the tools to do it all)
>around a hundred bux for the lumber for your footing form

>>29820702
What if you used >>29818398

>>29820810
Still need the rebar or the concrete will be brittle. They're a pretty solid choice if you've got access to a work crew and a truckbed-mounted crane or large backhoe.

Good luck moving a sheet of 4" thick, however-many-feet long by however-many-feet tall backed concrete by yourself or without major machinery though. Shit's not light.

And 4" of concrete isn't enough against most rifle rounds, heavy magnum pistol rounds, or any form of explosive.

Also quikcrete is *garbage* for suburbanites to patch the thaw cracks in their driveway in 10 minutes, it deteriorates rapidly (there's a reason people have to patch their driveways every spring) and has basically no structural soundness.
>it's also about twice the price of regular cement and a truckload of gravel
Its only advantage is it doesn't require a cement mixer.

>>29812945
You could use it like sandbags.
>Stack sealed bags
>Drive rebar through them for stability
>Spray with water to harden
It would work, but it's expensive as fuck

>>29821031
you will never get proper saturation nor will it cure properly because of it. you're going to have hella weak spots everywhere.

>>29821031
You want a bunch of rebar and wire mesh.

First dig a pit.
Pour a foundation on rebar and mesh leave rebar ends bent poking up around edges.
Once cured fill the pit in with dirt on top your slab.
Weld more rebar to the stubs around the base of the (now) dirt mound.
Bend the bar over dirt mound into a dome and add wire mesh.
Leave spaces framed up with wood temporary for windows and doors.
Pour concrete and dig out the dirt.
Put dirt on top, plant stuff.

Creosote isn't that good for you either. Which is a shame because it smells so fugging good

My idea was to get 200 odd acres of heavily wooded, mostly flat land which is cheap as hell where I live. Cut a small track in that you can barely get a pickup into, just far enough that you're hidden from the main road, and then cut a winding foot track in the rest of the way to keep people being able to get near in vehicles. Clear a decent sized area in the middle, then dig a 5' deep trench around it, heaping the earth on the inside. Anyone advancing has to now climb a 10' obstacle, while you have a nice berm to hide behind. Then plant blackberry bushes in the bottom of the trench as a natural spike wall. Then I'd build some a cabin with a hidden cellar in the protected area or something.

So wild idea time regarding fortifications.
Ballistic futon chairs/couch cushions.
Steel plates and ceramic tiles epoxied in layers of heavy cloth, covered in foam and upholstered to match your decor.
Still comfy to sit on, sure they would weigh a lot but its not like your going to be running around in your pillow fort of the apocalypse.
Just set it up (maybe folding support legs and velcro straps to keep it up and together). Then you can hunker or stash the senpai while you operate.
Pic related style with wheels on one end could let you set up a hardpoint with ease. Just flip it on its side zig zag like. Bunker. Couch cushion sized ones alone could be placed in good spots quick like below windows or edge of doors making that spot your crouched behind cover not concealment.
Unless you already have stone/brick walls but this is for the apartment/suburb home crowd.

Cant afford a safe room? No space for a bunker? Not any more!

Here's what it looked like before I started painting it. It's about 20 feet long with about 5' 5" internal height. Steel skinned and lined with with wood with a small plexiglas window in the back. My ultimate plan is to wall it off with steel reinforced cinder blocks and use it as an arms room.
I got it for free, but trucking it to my house cost me a pretty penny.
