Electromagnetic self-bondage locking stocks by Eric Oops

These self-bondage locking stocks were made by Eric Oops (NL) for miss Nina and based upon the electro magnetic door lock and timer method.

Details:

  • 4cm thick wood, about 115cm in length and weighing approximately 3kg.
     
  • The magnet is a Hekatron door magnet 24v DC. It has got 686N (80kg) holding force, so you can’t get it apart.. even when you put your weight into it. It’s connected to the wall outlet through a currency converter (from 220v AC to 24v DC) and an electronic timer in between. The timer can do a countdown from 24h to 1 minute.
     
  • The magnet was put in the middle because there was enough space. Placing it on the side (at the opposite side from the hinge) wouldn’t look that good and it would be more vulnerable. The way it’s mounted it’s that the subside is completely flat and no cables can be reached.

The stock must be fixed to a stationary object with a chain or rope shorter than the power cord (to prevent pulling it out or tearing apart).

But actually it’s quite easy to make.. you do need some tools.

I’ve started with 2 pieces of timber, cut at the right length. When you push them together and hold them in place with something (like the hinge will do later on) you can easily cut the holes with one of those hole-drill bits. The size of the holes is of course custom made for your own ankles and wrists. It does take a lot of sanding and moulding before it fits you.

The pieces of timber on the side act as stabilizers when closing the stock.

Getting the magnet in right does take a lot of measuring.. you want to have a bit of tension on the magnet when it’s locked. When it’s higher than the stock it doesn’t close all the way, when the magnet is placed to low, it won’t lock.

By the way.. just buying one of these magnets is also a good start.

  1. I want some! I am thinking of a way to be mounted spreadeagled using four of them while a fucking machine works away on me…

    Yeah, that would be interesting. You need a constant lubricant supply, though.

    Hi Eric Oops

    Very clever design and simple too -- I like it.

    You’ve obviously put a great deal of thought into this -- location of magnet had never even crossed my mind!

    I’m interested in your comment that 80kg holding (is that what they call ‘sheer force’) is enough. Did you try the same magnet for other SB purposes? I’m thining about using one as a single (final) bondage point securing my last free hand (possibly in a spread eagle) and could I pull my hand free (i know i can lift +80kg with both hands, but could a ‘snatch’ my arm free from an 80kg hold?

    brilliant stuff

  4. I am working on the lubricating mechanism for my fucking machine. I am using a windshield washer pump but my problems is getting the lube out of the tube in the right places. I do not really want to drill holes in the dildoes, but I may have to do that

  5. Patrick, what fucking machine have you got, BTW?

    Actually, you can use enema dildos. But they are not as long as you may need. Another possibility is to make a DIY dildo with a tube inside. For example, like here: http://www.likera.com/eq/plugs/diy-plug-1.php

    Idea: Would it be possible to put one on either side of the neck hole of a pillory-style stock?

  7. Of course it’s possible, but why? One should be enough, I think.

    i am an engineer and into self bondage so i thought a good project like this would be a good idea. i have used the magnet off a door thanks for the idea

    ps i am dyslexic sorry for spelling errors

    Good idea and nicely thought out but if used for self bondage there are some possible faults.

    1). Those cheap electronic timers do fail sometimes. This is easy to overcome, just use 2 timers in series, they won’t fail both on the same session.

    2). There are lots of ways that such an electronic timer can be set wrong. AM/PM error would only add another uncomfortable 12 hours, but what if the clock is set for the wrong day?

    3). the clock can be accidentaly set in “always on” mode instead of automatic. then it won’t switch at all.

    For some time I have used 2 different timers, an electronic one for precise time control and an mechanical one to eliminate any kind of user error.

    Still wasn’t happy with that setup though, so I bought a timer which is impossible to set wrong. It has one big dial which is labeled from 1 to 16 hours. If the timer hits the 0 hour mark it turns itself off. My backup timer I made myself and is completely electronic and it has multiple safeties built in against failure of internal components of the timer.
