Fucking Machines

Why are we not getting any input, (no pun intended), from women on this. I know that there are female engineers out there who could design this devise to please women.

I would certainly welcome any comments from the ladies ---- what do you want -- what don't you like -- how can I make my design do a better job

I would wish i could built something like that for my future girlfriend 😄

I built one for MYSELF.... BLUSH. Harbor Freight's best reciprocating saw ($65), a home made adapter that attached an old saw blade to a 1/4" pipe nipple running inside a 2" plastic pipe with a plastic pipe union as a bushing at the far end. The plastic pipe has two shallow cuts to accommodate the saw foot plate, and aluminum brackets attach it to the footplate with bolts & nuts. Any flanged toy can be used with a ring above flange tied to a 1/4 " floor flange screwed onto the end of the pipe nipple pushing under the toy foot. The total cost of this beast is under $90 AND you have a good saw to use too, but for solo use I need a 3 amp variac (New $65) to control the speed independent of the trigger (which I cannot reach when I'm DOING IT). If you use it ON someone, your finger on the trigger might be enough? Hope this gives someone IDEAS? ENJOY! I do! :-)

Try adapting a dildo to a saw-z-all -- one of the large reciprocating saws ----- or to a sabre saw -- both have variable speed -- unfortunately only short strokes---- but still very effective

I have not made or used one, so I cannot speak with any authority. I did take a Hitachi Magic Wand vibrator and attach a dildo to it--even made one that would be an enema nozzle. What I found was that while the vibration was pleasurable at first, after a little bit, it did not do anything for me and was a clumsy thing to use, so I gave it up. I have found that vibrators generally feel nice at first, but do not really do anything for me.

I'll say this just one more time. Stay away from high speed machinery like saber saws, drills, jig saws. Use a speed controller, not a variac. Forget the windshield wiper motor and it's dc power and home position switching. Forget the linear slides...just one more thing to align and get right. Use a small speed limited motor and ground the frame or someone is gonna get hurt.

Evidently switchable was awake in high school physics class. Take her completely correct advice about gear motors.

And, yes, I have built these and they worked very smoothly and quietly. They are a fun toy for the right recipient, but they are not the main event.

Sabre saws and drills already have speed controls built in --- saws will operate at speeds as slow as one stroke per second --- The wiper motor and it's pulse width modulated speed control give very slow speeds and produce full power at slow speeds -- some thing many AC motors cant do --- the switch in the F-machine -as I mentioned - is for an added feature I haven't described and not necessary for a basic machine --- by the way I used to work in a research center and build many different types of lab scale machines to test some of our screwball ideas -- also have some patents for the machines

You are missing the point. Saber saws can operate at low speeds, although 1stroke per sec is much too fast and a half inch stoke is too short.

The prob with saws and drills is that the can easily hit speeds that damage. One small move of the speed control and we have 10 strokes per sec. That's why we build machines inherently limited to safe speeds.

One writer wondered what the girls want. They want safety and pleasure. They want noiseless toys. And above all they want things to be controlled and a guy who will keep them free of worry.

Keep the windshield wiper motors in the car, keep the draw slides in the toolbox. If you are going to play with this stuff, do it right or find someone who can. Don't expose your honey to a danger she knows nothing about.

And keep your 110 volt power under control -- use only 3 prong cords and outlets -- as you said - ground the frame of the motor--- remember 110volts is very capable of killing

Unless you have access to a good hipot tester **STAY AWAY FROM LINE OPERATED DEVICES* It is just that simple. Connecting the ground wire to the motor frame is not safe. I have run across many outlets that are wired backwards or have defective grounding. Even if you run a GFI protected cord that can let enough leakage current into you to kill you before it trips. Run it on batteries and be much safer.

The motor thing, in general I tend to agree that you are best off not pushing a baby carriage with a tank. That is the device should approximate the load. But, if it is just a difference of speed, that should be able to be effectively controlled. This gets back into electronics design, but it is quite easy to figure out the "range" of the speed control you want to be working in and create a circuit with fixed resistors and or a trimpot, and a small value pot for the operator to adjust that will just accommodate that range. If you are building a PWM controller from scratch you can also limit the range in software.

Adjusting stroke is harder in these systems and a bigger concern. I have been pondering this for a while and I think when I build my machine I am going to use a DC motor that drives a wheel with holes in it for different degrees of eccentric so the stroke is set by the eccentric that you are on, and the reciprocation rate is set by the speed of the motor. There are also possibilities for using electronic (lead screw based) linear actuators, but they tend to be expensive and (generally) have low reciprocation rates. Also, I suspect that most of them are not built for continuous duty. Still they may be worth looking at for some aspects of the device. Perhaps setting the overall bias of the stroke or the angle.

I have also been pondering linkages to allow rotation and vibration, as well as heat and perhaps even spurting. And a computer based control system that tries different things and learns what you like, and can also pace a session so it can start out slow and slowly build up.

Sadly I have hundreds of projects in the fire at any given time and this is one of the many. I *do* ponder it, and I *do* have a lot of pieces for it. If you are around the Ithaca, NY area and have an interest in helping to build this or are a female and have an interest in testing this.. Please drop me an IM!!!

I have tried it once with a good friend but the dildo kept popping out which was a great shame, what i would like to try is the VENUS 2000 on a very load speed for a long period of time :-)

This may sound strange. I like to ride a Sybian while on my period, especially if I am cramping badly. The vibrations not only simulate my clitoris, but also heighten the cramps. The mixture of pain and pleasure is incredible, especially when someone else is controlling the speed. Before I mount the Sybian, I like my legs bound, so that my ankles are tightly pressed against my upper thighs, giving me no where to run once on the Sybian. In addition, I really enjoy having my hands tied and suspended above me. In this position, it is almost impossible to dismount, making it quite a turn on for me and my partner. I have done this with both men and women, but prefer the ladder because they seem to relate to the predicament and take full advantage of my bleeding exposed pussy. Just a couple of week ago, I was at party and met a redhead girl willing to give me a Sybian ride, even when I told her I was on my period. We immediately went to the host's basement, I stripped, removed my tampon, and then she bound me straddling a Sybian. I am typically dominate, but it felt great to let her control the speed of the vibrations. I was entirely helpless to dismount, as she kept cranking up the intensity, blood dripped from my over simulated pussy, running down the sides of the Sybian (had to clean it thoroughly, afterward). I came at least four times! Too bad I didn't get her contact information, she was relentless. :-)

Most machines are simply reciprocal, being driven by a crank similar to a bicycle or engine crankshaft. This would cause the back and forth motion to be sinusoidal, which isn't very natural and which makes me wonder if it doesn't get a little boring after a while.

Here's one I've not seen before that uses compressed air to pneumatically thrust the toy into the recipient which seems to me to be much more natural and potentially exciting. Even though this is a pro porn scene and the receiver could be faking, she appears to be having a wild time.

... the pelvic straps seem less like BDSM restraints and more just to keep her pelvis in alignment with the machine, which given the eventual ferocity of the thrusting, is probably a good idea.

That compressed air job looks LOUSY. That is a terrible fucking motion except for a handful of strokes to break up a rhythm. I haven't seen anyone fuck with a stroke like that for more than a few strokes.

Her fake moaning is annoying and her pussy also looks dry as a bone in that video. You can tell by how much drag there is between her skin and the dildo.

I have posted about it before and have been fucked by the Cathedral (or is it Crystal Cathedral?) both anally and vaginally several years ago, and I'll tell you NO MAN can compete with it for stamina. That thing can do me for hours and I wouldn't be bored.

Radio: The problem is 99.9999% of all of the air cylinders I have seen are simple single or double acting, they go all the way in or all the way out. Actually an awful lot of them are just single action and use a spring for the return. There is no way to make a nice fucking motion with this type of arrangement. I have worked with servohydraulic systems over the years. That would be the cats meow, but they are expensive with big E. Just the servo valve will set you back around a grand. There is a lot of stuff that is required for that kind of a set up. I think for your average home shop type who has a little to splurge, an electronic linear actuator, which is a reversible motor with a lead screw, is the way to go. You can do different speed and depth thrusts. For the poorer DIY home builder types you are probably looking at a motor driving a disk or arm with an eccentric like a locomotive engine. If time is worth anything I think the linear actuator would get you a lot closer a lot faster. If cost is he consideration you should be able to piece the motor/arm/eccentric together for nothing if you have a decent shop and do a lot of curb watching.

The thing I want to do that I believe is unique is have a feedback mechanism. I want to make a smart toy.

I built one using a truck wiper motor and a ball bearing drawer slide--- variable speed --- about 6" stroke -- could make it variable stroke length ---- fits in a plastic tool box --- also added a special tease feature --- whole thing cost about $75

I have a friend who has one. She loves it. But she did say that you need to use a lot of KY. She told me that she was used to just laying back and letting it do it's thing. She had it mounted on a heavy table and she would position herself sort of lying on a recliner chair. She was using it and she started to dry out and it almost tore her.

. . . you need to use a lot of KY. . . . she was used to just laying back and letting it do it's thing. . . . she started to dry out and it almost tore her.

Absolutely, if you aren't less than 20 years old with an unlimited supply of juice, laying back for an hour getting fucked by by one of those machines will definitely dry you out. Keep a squeeze bottle on hand so you can squirt some lube where needed as you are impaled. 😁 You don't even need to stop the machine, just apply it to the labia while it's running.

Actually, K-Y is a little pasty for this and diluting it with water to thin it out or using a less viscous lube is much better.

I would love to try one of big well engineered type machines you see in some porn, I would love to be restrained and mechanically fucked "against my will/ with protest"

Where have people tried this ??

@molliewhite, being restrained and fucked by a machine is one of my fantasies too. Here's a link to some free video samples of fucking-machine porn:

If it's like hogtied.com, you get four free looks and then it's pay to play.

I have never been around one but with the right playmate it could certainly be a lot of fun. Unfortunately, the good ones are expensive. Strippers say the best is ShockSpot and I've been personally informed they'll spend good money on one.

I haven't used anyone, but I have seen very much videos and pics.

As I love forced orgasms, I want to use them on someone very much.

To simulate fucking machines, it would be useful to verify electrical TENS devices by placing electrodes on vagina, belly and butt, legs. It is my advice. I have been using that on myself. But I am a man wanting to be sissyfied. So you should enjoy that on yourselves.

I actually built one. A heavy duty low speed drill, attached to a bar that works like a wheel with a pin, hinged to pvc pipe through another pvc sleeve. Then I used a heavy duty variable speed dial switch to control how fast it goes. It doesn't look very pretty though, but it fucks!

I've used it about 10 or so times on a few different partners and it's worked pretty well, both vaginally and anally. It's noisy so it certainly doesn't sound sexy, and a couple women couldn't get into it at all. But others did and it was like I had an 'orgasm on a dial'!

I am thinking that a stepper motor would be the way to go to create motion. To control the speed just step it faster. You would have a home switch for the back of the stroke and either have an adjustable position stop switch for the end of the stroke or just vary the number of steps. Stepper motors are cheap and have full torque at slow speeds. You could make it simple with a timing circuit and a few chips or a little computer like a raspberry or arduino.

I have a fucking machine and love the feel of a big dildo penetrating my ass over and over. Cost a bit but have enjoyed using it over the years. Great for anal or vaginal play and when you get it set up just right, it will milk the heck out of you. If you want to get a feeling of a guy penetrating you this will do it. It cannot replace the feeling though of his hot cum filling your hole and the erotic effect of it dripping out of you. Nothing quite like the real thing but does great as a substitute.

I use a normal muscle massager or a vacuum cleaner. You will be surprised how fast it works.

I have noticed my local sex store is now supplying these new tools. wondering if it is worth the investment

OMG that looks like such a rip-off! First, while I don’t have a pussy, I haven’t known any woman to say that ‘spinning’ a toy is sexually stimulating. But second, even it is is her thing, $250 for a super cheap ass drill and plastic adapter and a vac-u-loc dildo?!? Surely those could be bought for less than half that.
