I've made a complete setup, which I'll walk you through here, in order to show the considerations, and preparations, which are necessary, in order to get a 'well-working' self bondage session.
Of course there's a tight connection between the type of self-bondage, you'd like to make, and the necessary preparations, but I've made up my mind, to make a walk-through, on this one, and then let you modify it, to suit YOUR preferences.. *S*
The self-bondage-session, I've picked for this, is the one you could call "Selfbondage with vacuum-cleaner stimulation".
1/ If you'd like to use a timer-switch, to start and/or stop the action, plugging the timer-switch into your wall-power-outlet, would be a pretty good place to start - along with controlling, that the time shown by the timer i actually correct.
In order to find out, if the timer will actually shut on, and -off as desired, you simply set the timer, to start i.e. your vacuum cleaner five minutes after plugging it in, and to (subsequently) turn it off again one minute later. In this way you'll find out, if the timer is performing, as you'd like it to - and don't forget to turn on your vacuum cleaner, prior to plugging it into the timer...
2/Next, it's due time, to place the keys, which will let you release yourself, and to 'set' the candlelight-delay.
As you'll see from the picture above, I'm using my candlelight-timer, which
you'll get more information about, if you click here: More.
The ring, attached to the sewing-line, to the right of the picture above, is an
important detail to remember, and I'll be comming back to this a little later.
As you'll see from the picture, I've set the line to burn through - and release
the keys - approximately 30 minutes from start. (I know, that the candle will
burn, at approximately 2 centimeters (close to one inch) per hour, which gives
me the result, that 1 centimeter = ½ hour. If the result will turn out to be a
delay of exactly 30 minutes, I cannot say, but it will be pretty close).
I've bound the sewing-line to the blue chain-link, on the crossbar, on my timer-candleholder, and have placed the crossbar, at such a height, that it will give me app. ½ hour's delay, upon which I've let the clothespin grip the line, just below the crossbar, to prevent the crossbar from sliding upwards - which would probably move the sewing line out of reach of the flame, when I attach my BDSM-Keys to the other end of the line.
Prior to burning through the sewing line...
-and after...
At 'the other end' of the line, there are a few details worth mentioning, as
well.
First of all, it's important, that the line will be able to 'move
unobstructed.
that's why I'm using a short piece of chain, with a key-ring a either end, to
avoid having the line running across the (rugged) edge, (and you should
also notice, that I'm having one hook, for the sewing line, and another one, for
the rope, carrying my handcuffs).
At the picture above, right, you can see how the 'safety-ring' which I tied to
the sewing line earlier, prevents the sewing line from just 'slipping through'
the key ring, at the chain, which would leave the keys, with the sewing line
attached to them inaccessible on the floor - where I, with my wrists locked in
the handcuffs, tied to the ceiling ring - could not get at them...
Now, the safety-ring will secure that I can pick up the keys, from the floor, by
dragging them up, by use of the sewing line.
3/ Here I've set the chair, on the floor, below the ring, with the vacuum
cleaner hose bound to the back of the chai, in order to keep it in place, no
matter what.
For this purpose I've made use of a couple of shoelaces, purchased ijn my local
Tiger store, from where I tend to re-supply, at regular intervals, at a very
cheap rate...
My regular visitors might have noticed, that I've modified the seat of my camera
chair a little, in order to allow 'full frontal access', and have been giving
the seat two layers of "Hempel Classic Varnish", which has completed
the project bondagechair.
You should - by the way - make sure, that you turn the 'vacuum cleaner exhaust'
in a direction, where it does NOT blow out the candle - which would be a
disaster. Please remember to make certain, that the airflow out of the vacuum
cleaner travels somewhere safe - away from the candle..!
4/ Finally, it's the handcuffs, which are going to get into place, and here's a few things, worth remembering as well:
At the 'top end', through the ring, I pull the rope through the ring, one end
from either side, and tie a reefers knot on them 'across' the rope, coming up
from below - like I do, when tying the panty-knot.
Doing it in this way, it will be impossible to pull down the loop of rope,
getting at the knot, when being locked inside the handcuffs, which is the exact
point !
At the lower end, of my rope loop, I pull the rope through the chain between
my handcuffs, pull them through the loop, and let the loop tighten, which will
make it absolutely impossible to remove the rope from the chain, when I'm locked
into the handcuffs.
As you'll see from the picture, at the right hand side, I have made certain,
that I can get enough 'room' to unlock the handcuffs, when the keys are
released.
By the way, do NOT use 'hinged handcuffs' for self bondage, it's impossible to get out of them, keys or no keys, I have tested it !
5/ Finally I place the stimulation-device as well as the rope, in a place,
where I'll be able to reach at it, when sitting on/(in) the chair.
Now I'm just about ready, so I light the candle, put on the sausage-board, sit
down in the chair, tie the stimulation-device into place, attach the vacuum
cleaner hose, and control that I've remembered everything...
...prior to locking my left wrist into the handcuff, turning the vacuum cleaner on, (or let the timer do that) upon which I lock my right wrist into the handcuff...
-and if you'd like to see the video, then click this picture: 
Well, I re-discovered why it's a bad idea, to let the handcuffs 'carry' the
arms - it hurts - quite simply.
That's the reason why I got the idea, for the 'self-bondage-handle', which in
effect, is a piece of wooden stick, app. 12" long, with a hole through the
middle.
This allows for the 'handle' to be placed just above the handcuff chain, allowing me - being locked into the handcuffs - to hold the stick, reliving me of the strain to my wrists, while being locked in the handcuffs..!
