Easy spanking machine

Post by Selfsub »

Has anybody mabey thought about building a spanking machine using the old motor/mechanisim from a car wiper.
It should be easy enough to just go pic up one from your local scrapyard.
I saw cars like BMW and Audi usually have "faster" wipers so the motor or mechanism on them should give you a nice enough spanking.

A wiper from a motor car might be able to whip, but lacks the power to put the force behind a spank.

Wiper motors tend to be in the range of 120 RPM, which means they are too slow to effectively whip, cane, or spank. The are,m however, quite reasonably powerful at around 40 in-lbs torque, and make a decent if slow fucking machine.

Don't you need like a load and unload mechanism to really hit? Planning a better post when I have time. :roll:

It's an interesting design problem. As Shannon says, there are two requirements, a fast stroke and a slow return. The stroke is "explosive" - hard and fast.

A simple rotation can't achieve this so you have to use a mechanism or motor control. I have seen people suggest a cord fixed to the end of a desk fan blade, but whilst this might be fast, it isn't a strong force and anyway a lot of whipping on the same site will be very unpleasant (and not in a nice way!) and could easily break the skin and seriously wound.

You could use a motor to wind up a coiled spring or tension a bungee cord, then have some kind of release to let the tension swing a whip. Stepper motors could provide both slow and fast rotation, but powerful stepper motors are not cheap, and would need expensive driver control. I did make quite a good machine using a DC motor supplied with about twice its rated supply voltage, pulsed to rotate under full power for about 240 degrees, then speed-controlled for a slow return to a parking position ready for the next stroke. A more modern method may be to use the type of electric motors used for model aircraft - these can be VERY powerful but again not cheap.

Solenoids (electromagnets) don't work - their force is inversely proportional to distance from closure, so maximum force is applied when the armature is touching the core, which means acceleration is lowest when separated, and the effective stroke just doesn't happen with enough force.

There are some interesting "cam" configurations which might work but need some complex design.

Pneumatic rams are worth considering, but you need a decent compressor and they aren't exactly quiet in operation!

I hate to be a bore, but by far the best method is to find a nice, friendly and sadistic Dom(me) :twisted:

I just thought the OP was planning to attach something to the wiper arms to provide the instrument. It would be a trick to house the motor, transmission, linkage and arms to do that. Even still, you would get this :

Still, it did spawn at least 1 new idea, so thanks for posting.

A Jennynator? :idea:

I could have a whole army of them, and conquer the world! :whip:

Muahahahahahahaha!!!

(megalomania is fun :mrgreen: )

Jenny (the real deal).

Thanks for the input guys.
It seems that it will not work.
The idea of the fucking machine does intrigue me thou.

Perhaps not with a windshield wiper motor, but a motor from a discarded cordless drill is at least as easy to come by.
And that definitely works (YouTube link).

That's what I was thinking.
