Battering Ram

[Cork]

best way to make one?
Lockpicks are great for getting in certain doors, but sometimes you just gotta smash the fuckin thing in.

What are police ones made of?

How could i make an effective one using materials from my local hardware store (home depot)?

Any input appreciated :D

There was a show on hacking that featured a homemade. I can't find the link at the moment as I forget the name of the show. They took a large pipe, PVC maybe? and filled it with cement after they drilled a handle into it. Simple enough.

I don't know how you're going to inconspicuously lug the thing up to where you want to get into though...

lol, ill figure that out later

ACTUALLY i just realized that on many tv shows the FBI or w/e just kick down locked doors.... i am an athlete and have strong leg muscles, how much force do i need to kick it down? A battering ram would be better either way anyways, but still..

its gotta be flat and heavy obviously. but it also has to be rigid, such that the more of the momentum will be converted to force (reduction of impact time). steel tube filled with cement sounds fine i reckon. cement is around 3100kg/m^3, so a 0.7x0.1mm cylinder will be around 17 kg. assuming you let it swing like a pendulum first to build up momentum, and you lunge forward on the actual hit such that the pendulum is at the bottom of the arc(where the velocity will be the highest), i would guess that it would be moving at about 2m/s. a conservative value for impact time would be 0.05 seconds, if its a hard material like concrete, so youll get an impact force of about 1360 Newtons. which sounds like enough to at least loosen the screws on the lock

but in the end its a battering ram, an invention thats been used for a long time to wreck shit. im sure you could figure it out.

I'd suggest buying a manual pile driver like this:

and filling it with concrete to get the weight you want. Battering rams and pile drivers are both made for whacking things with a large impulse force so it's ideal.

If you want to go fully DIY, find a chunk of thick walled metal tube or bar stock and weld handles to it. The thinner the tube/bar the better as the impact area will be reduced, increasing the force put on a given area.

Weld handles onto a 4"-6" x 20+" steel pipe and then fill the pipe with cement.

Empty a fire extinguisher, take of the valve, fill with sand, weld handles on, put a bolt where the valve used to be, stop sand coming out. I never had a problem taking an axe to a door and destroying the hinges.

Honestly just go to some abandoned(or not) house and try it. Aim for the right of the knob. Just remember to kick forward like a muay tai push kick.

mount that shit on a car and ram the door

mount that shit on a car and ram the door

Best advice I've heard. Or maybe a truck, amirite?:)

mount that shit on a car and ram the door

dude thats great but the target door isnt in a position to drive up to. Theres a concrete staircase and i like my car. alot.

Im strong enough to lug a ram up there and bust the door down, i just need help making one lol, i have no idea where to get concrete other than stealing it from a construction site. Thats another matter altogether, lol

It probably wouldn't be as easy, but a sledgehammer or axe would probably work.

Ok how about this. drill 2 holes in the door near the lock, pass a chain thru the holes and attach to the towing loop on your car. then drive in the opposite direction of the door. Hopefully it will rip down the door or at least rip the lock away.

Theives have used this method to steal ATM machines.

This is what happens when I leave my post for a week to get my schedule on track.

Anyways, why go through a door when you can go through a window?

...that method would work, but it's overkill for the average front door. It's a bit like using a wrecking ball to smash a window. ;)


uPVC doors can flex a surprising amount and absorb a lot of the energy of a battering ram - they just bounce back rather than crack. That's why they have three or four automatic deadlocks to prevent someone from bending a corner up and getting in. You need to actually break the uPVC frame away from the house rather than try to break the lock...impulse force doesn't work.

However, I haven't seen that style of door much in the US (well, on US TV shows anyway) so the typical wooden door wouldn't offer much resistance.

[Sal, a man-deer]

Just kick the door down.

[Nereth]

The thinner the tube/bar the better as the impact area will be reduced, increasing the force put on a given area.

On the other hand, some shitty doors (especially interior ones) can get a hole punched clean through them without breaking open.

So you don't want the door itself to yield and reduce the instantaneous force, it's counterproductive.

I'm sure you understand this, I'm just saying it because unqualified statements like "the thinner the better" tend to make people give themselves free reign, he could have ended up with a very long chopstick ;)

thin on one side, wide on the other :thumbsup:

I've been burgled, and the professionals use a crowbar (http://en.wikipedia.org/wiki/Crowbar_(tool))

[Sentinel owl]

Yes. Leverage beats momentum, in this case. Also, if you must insist on battering, aim for the side opposite the hinge. Don't aim for the middle. You're really trying to bust through the WALL frame, because that's what will be the weakest spot.
