frenchdungeon -> mechanised bondage (12/1/2010 11:39:27 AM)

good i got your attention...

i realise its a subject often repeated here, but i am not talking bdsm furniture ready available in various fetish stores, i am talking about the odd and
unimaginable contraptions, the perfect bondage machine, be it real or fantasy

as much fantasy right now, i would love to built a large frame of metal with hydraulic cylinders in all corners, to help stretch the sub, like some kind of rack table, except up-right, suspended by the ankles

would love to hear what most here could imagine or come up with



Termyn8or -> RE: mechanised bondage (12/2/2010 11:59:00 AM)

I thought of things similar but not quite what you were thinking.

Something that would make someone like a marionette, control motion, not just prevent it.

Wrote a story along those lines a few years back, futuristic scifi, super heavy on the kink. If you want to read it lemme know, there is a link [because I've been published :-)].

It would have to have safety links to avoid breaking the sub.



Termyn8or -> RE: mechanised bondage (12/2/2010 11:09:23 PM)

You'd be surprised, maybe, to find that safeties and other limitations are better implemented in the hydraulics than the mechanics.

For example the pump and pistons could be sized to really limit the force applied, and failsafes for that (just in case) would involve pressure releases that are a simple piece of metal of the correct thickness and hardness. Hydraulics is better and more reliable, especially in a sealed system. That's why it is used for the brakes on cars.

Hydraulic pumps (electric anyway) stop operating in a power outage, as do electromagnets. Better than tripping around in the dark trying to unstrap someone. I have given these things some thought and if anyone has ideas I am up to discussing them. It doesn't matter if you trust technology, it matters how. Things that must happen.

For example some indulge in the very dangerous "sport" of selfbondage. The only unequivocably acceptable form of guaranteed release is ice melting. And that's only good in warm weather. It still doesn't guard against absolutely any happenstance, like a fire or WW3 or anything like that, but neither does anything else.

Thing is, people will do it. Should you ever even gag someone who is bound ? Hell no, things could happen. But sometimes the bold go, and the rest do not. But those who do should just know what their doing. Rely only on the laws of physics. Nothing else is as near to foolproof.

And all read those words :

"NEAR TO FOOLPROOF". Near is the operative word here.

+1 on the hydraulic failsafe effectiveness. Never used it in bondage, but I have played with home 'eco-friendly' heating/cooling systems and waterfalls that had hydraulic elements, and they seem to just have more available ways to shut them down.



curbisub -> RE: mechanised bondage (12/18/2010 8:19:53 PM)

Sounds good, sounds like something a Chriopractor uses to make the spine longer as he adjusts their spine/hip/neck joints.



Buzzzz -> RE: mechanised bondage (12/21/2010 4:07:42 PM)

lookup Gord on fet... He is very good with that stuff



xssve -> RE: mechanised bondage (12/25/2010 12:20:51 AM)

I've been building up a collection of parts, I have the mechanism from one of those chairs that rises and tilts to help disabled people stand up, its driven by a worm gear and an electric motor, and several of the rams from an old, articulated hospital bed including the controller - these are also electric, worm drive rams that telescope, though very slowly.

I really don't have room for anything elaborate though, I was actually thinking of using them in a fucking machine, to adjust for angle, depth, stroke length, etc., but I'm leaning more towards RC car servos, small, but wireless and strong enough for what I have in mind - industrial servos are nice, but very pricy. I have a DC pancake motor out of a small golf cart for the main drive, so it would be variable speed.

I think the rest will come in handy, once I refine the design and figure out something a little more compact and portable.

I bought the chair lift at a yard sale, and salvaged the rams and controller from the bed out of the Salvation army discard bin, but I just removed the hardware and threw the frame away, it might be a couple of years before I get around to doing anything with it, and I have plenty of angle iron from other bed frames laying around to fabricate a frame.

One wouldn't want something that would dislocate a joint or anything, I'm thinking more in terms of positioning, the wormdrive rams are very powerful, but very slow moving.

Even the low end electric beds like this are pricey, but I see them at thrift store now and then (this one had a broken frame joint, missing a rivet basically), and you might check salvage yards, or look for old hospitals being torn down, you can salvage all kinds of crazy shit.

Other mechanisms worth investigating are the footrest mechanisms on old Laz-E-Boy recliners, or the frames of hide a beds, etc., you can often find them simply abandoned, or in the salvation army discard bin - helps if you have a truck and a place to take them for disassembly, they're usually riveted rather than bolted, but a cordless drill or angle grinder and a decent socket set and some wrenches, and you can break them down pretty fast - the hard part is trying to remember how they go back together, as they're springloaded, lol. Watch your fingers too, they bite.



Termyn8or -> RE: mechanised bondage (12/25/2010 4:52:22 PM)

They bite ? Sound kinky.

The things you're talking about are not hydraulic, but that doesn't mean it can't be done, by any means. For safety's sake maybe spring loaded scales. Ha, suspend-a-sub, and it weighs them too ! But the point is real brute force should be avoided whenever possible. For example you could use a garage door opener type mechanism for suspension, but for stretching it's a whole different story. You can't tell just how much force you're applying. Even strong bungie cords as a "vehicle" for the force would be good, you can see how far they've stretched.

They should just drop us off at a landfill and we see what we can find. Mechanisms from recliners, sofabeds, imagine the possibilities. In a throwaway society, there is alot to find.

More later.

hausboy -> RE: mechanised bondage (12/26/2010 9:14:44 PM)

I see a trip to the emergency room in someone's future....

well.....job security for me! carry on...



xssve -> RE: mechanised bondage (12/29/2010 3:10:02 PM)

No, I would avoid hydraulics- messy and difficult to calibrate, with electricity, you can always just pull the plug, with hydraulics there is going to be residual pressure to deal with.

Stretching I do by hand, though I do have designs for some spring loaded devices, but these designs tend to be user controlled, the springs are for retraction rather than expansion.

The exception might be these plate hangers I found, one of which I've modified into a labia spreader - it has spring loaded hooks around the outside of a wire circle that grasp the plate - I reversed the springs and hooks so they pull outward rather than inward, but the springs are pretty weak, not much stronger than the ones you find in retractable ball-point pens.





windchymes -> RE: mechanised bondage (1/1/2011 8:48:04 PM)

I find all these ideas pretty darn hot :), but rather than using anything motorized or hydraulic, maybe just stick with ropes, pulleys, weights, etc. that are controlled manually, so you don't have such a risk of something going horribly wrong mechanically and orthopedically.

If it's a mechanical look you're going for, or just extremeness (I made that word up), you can bolt someone permanently (until you remove them) to the floor or wall or onto a Sybian or something like that using metal pipes, bars and other hardware. Check out devicebondage.com, they do a lot of that kind of stuff there.



SpaceSpank -> RE: mechanised bondage (1/2/2011 12:55:41 AM)

Actually, with the "manual" control pulleys and ropes system you can still do lots of damage if you don't know what you are doing. They allow you to pull/lift far more weight than you normally would be able to... so if you set up a "serious" looking pulley system in order to make it look big and menacing, you may just wind up dislocating something before you realize it.

No matter what the system is, manual pulley/lever systems, springs, hydraulic, pneumatic, elctric servo's, mechanical crank/drive systems or any other funky getup you can imagine... make sure you research what you're actually putting together and how to limit the movement AND the power both to acceptable levels for use.

You could have a gigantic mechanized beast of a rig, with giant steam pipes, huge gears and a lumbering diesel engine. Something that would strike the fear into the hearts of anyone being prepped to go into it... but if you have it set up right, it's all show, and wouldn't even be able to rip a piece of paper apart unless you wanted it to.



Termyn8or -> RE: mechanised bondage (1/2/2011 5:28:14 AM)

Steam pipes ? LOL.

Anyway, safeties are a big concern no matter what technology you use. And it can't be a simple breakaway. I had a rig that would support my entire body weight, but I know a couple people who could just break it with no problem. What might pull one person's arms and legs right off of them wouldn't even hold others.

I like the idea of those spring scales, then you can see how much force is applied. If she weighs 200 lbs., you have that figure, but then how much force to apply ? You have to know how strong the sub is. I see a big mess. I used to be able to break handcuffs, the real kind. I know people who can probably still do it. You could lay a quarter ton of force on them and they would probably say "Ho hum". But others would be torn to shreds.

Ever see a skull saw and comtemplate it's design ? It drills through the skull and then stops the moment the resistance stops to the feed (pushing) force. Marvelous, but I think in this case something that detects the dimension changing and stops, would act too late anyway, after the arms are pulled out of the sockets or something. There is no way to pre-predict at what force the damage occurs.

Anyway, somone mentioned a sybian ? MUA HA HA HA HA

I envision a type of horse, like a mechanical horse. It has a saddle and a hole, the "member" comes through the hole. But that is jack shit, this is where it gets diabolical. When she sits down, you pull a lever that is not accessible to her, which removes the footrests that she used to climb up on it. Also, in the design there is nothing on which to hold on, to lift one's self off the machine. And of course the foot rests are out of reach.

Bondage without a single strap, manacle or anything. She can't get off it. There is nothing to grab and nothing to step on, and you control the "member". A crankshaft assembly underneath drives this invention from hell (that's where I got it) and the "member" is inflatable with hot (or cold) water, variable in size, stroke and speed of course. Most of that part of the mechanism can come from an old sewing machine. I need someone to envision what I do and help design and build the "horse", the frame, etc. of the appartus. Many subjects must be found to test it. To see if they like it, and little beknownst to them, the security.

MUA HA HA HA HA HA.

Understand what I want here. No straps, not even a seat belt. But totally inescapable. You can't get off of it, there is nothing to grab, and your feet don't hit the floor, or anything. the saddle must be designed so a pushoff is impossible, no mater the strength of the "rider".

I have a good part of this design in my mind already, but there are a few details. Some might say it is impossible, and to them I would like to say "Well stop over and try it". Find out.

And when they beg to get off of it, then they get ten minutes after that, just to prove who is boss. Of course that is agreed to in advance.

I got a lathe, drill press, a small milling machine, a bandsaw and a MIG welder. I know where to get stock in this town. Aluminum, even higher alloys. I was thinking of making some really kickass chastity belts and rivaling other manufacturers, but I never imagined surpassing Neosteel. They have decades into it, and I haven't even begun.

Going out looking for scrap is a drag. I had a neighbor, we called him Eureka because he was good at finding things. One day he has this aluminum in his trunk and it is nice. It wasn't extruded but it was nice straight pieces of about the right thickness and the right width for,,,,,,,many things. He didn't want to give it up. I had to give him ten bucks for something the scrapyard would pay $1. If that !

So I can just go to the scrapyards. I know that game. I could make a deal where I pick out what I want and then pay what New York is paying, and get the material cheap. I am fairly well networked in this town and I know I can cut a deal somewhere, absolutely.

In metal restraints of any kind, in fact any restraints, to find the state of the art, look to Germany. A few of the top producers of restraints are there, and their prices are, well if you have tio ask you can't afford it. Tell ya what, I am going to give you a searchword, use it and look at what they have, and this stuff is supposed to be humane ! Of course that does not concern us.

The searchword is : Segufix

The problem is you can't buy it. I have found their stuff on eBay from time to time, but not all of it. You could fake some credentials and get it, but then, could we not just build it ? Make it ?

SpaceSpank -> RE: mechanised bondage (1/2/2011 9:18:34 AM)

The only problem I see with that design is that if they can sit on it, they have something they can put their hands on to lift themselves off. All they need to do is lean forwards or backwards (or even too far to the sides) and they will simply slip off the device and go crashing to the floor.

There's really no good way to do it without some form of restraint to keep them on top. Unless the member you are talking about is going in very deep and never moving out, it's always going to have a time it "runs shallow" and they can simply fall over if nothing else is holding them there.



Termyn8or -> RE: mechanised bondage (1/3/2011 8:24:09 AM)

I think it's Ripley's that has that chair that once you sit in it you can't get up unassisted. It would have to be something like that, which uses gravity. I haven't worked out the details, and it probably won't be easy. I do think it's possible though.

If I try and fail I guess I would have to some straps or something on it :-)

xssve -> RE: mechanised bondage (1/7/2011 8:27:57 AM)

I always thought the ultimate would be on of those frames like you see at fairs and the like, the zero G simulator sorta thing, with Two concentric hoops, that rotate in opposite directions, the "rider" being suspended in the center, and can be put into any position, 360 degrees in any direction - I can't remember what they're called.

That would be fun, although you'd need a really big room to put it in.

Most of my designs are similar to this, rocker type things, the sub would be bound more or less in a fixed position, but you could tilt them forward or back, up and down, spin them in circles, flip 'em over, etc.



Termyn8or -> RE: mechanised bondage (1/7/2011 2:39:00 PM)

I believe the word you were looking for is gimball. It's was used with the old gyroscopes for navigation before they were replaced with the laser gyros which read directly, and also on better quality (phonograph) turntable arms.

But now that you mention it, ve might be able to fint uses for ze device yes ?

I'm well aware of this, the point I was making was having the human factor of being able to cease activity immediately as opposed to having to shut down a machine.



Termyn8or -> RE: mechanised bondage (1/9/2011 12:08:51 AM)

They are all machines really. A lever is  very simple machine. A pulley is a form of a lever.

Let's say we build a contrasption out of hydraulic cylinder(s) etc. rather than the pully or a simple lever, but in this case the pressure is appplied by a hand pump rather than an electric pump. That makes it no less a machine, just like the simple lever or the pulley.

A simple pulley gains an advantage in force by placing the fulcrum closer to the load, and this is of course at the cost of distance. A compound pulley, like an engine hoist might use a compound pulley, which does exactly the same thing as does pushing hydraulic fluid into a larger piston from a smaller one. A floor jack does exactly that.

I simple riding crop is a fine example of the principle in reverse, where the brute force is traded for distance. The fulcrum is pretty much at your thumb (or somewhere on your body), and is close to the force. The stinging, welt producing end is the load side of the lever. Just like in a gearset or transmissiom, you can trade either way, but the amount of actual work (by scientific definition) does not change. Just like in electronics, a transformer could step the voltage down, for example taking 120V from the wall at one ampere, and dividing it down to 12V, but at ten amperes. In some cases the transformer is worked the other way, say the 120V is converted to 1,200V. In that case one ampere in will only get you 1/10th of an ampere out, but at ten times the voltage. Power (watts) is the product of volts amd amps, so the actual power level has not changed.

This is a constant in all simple physics. You don't create nor destroy energy, you just make it more usable for whatever purpose.

The principle by which any machine works has little or nothing to do with it's safety. It is by design that things are made acceptable for use ( EEEK ! ), not the specific medium which transfers the force.
