For some time I’ve looked through different videos that more or less show details
on fucking machines, and have picked up bits and pieces here and there.
The result is my own working DIY fucking machine. Though, it must be said
that it’s a prototype, noisy and no beauty.
You might find your own way to assemble it.
Have fun!
Below I’ll describe the different parts and possibilities.
Motor
I’ve looked for geared electro motors with around 250-300 rpm, but most of the available are too small and not strong enough.
My choice was a 12V wiper motor. It’s not expensive and is powerful enough to do the job. It’s a little noisy, but not too bad.
Wish: 268 Nok
Speed Controller
You need a way to adjust the speed. This one I chose because it comes with a box for the electronics and is cheap. This controller supports any DC-voltage between 9 and 60 volt, and should handle any motor in this range. If you plan to make a remote-control, please note that the switch carries the power to the motor and a remote cable can’t be a signal cable; the cross section is to small.
Wish: 113Nok
Power Supply
As the motor is 12V you need a 12V PSU. There is no info enclosed with the motor, but my PSU delives 3A, and that’s not enough. I recommend a 5 or 6A version.
Wish: 96Nok
Assembly
Depending on the way you assemble this, you might need an extension for the motor shaft. I used a 8mm joint nut 25mm long. That enabled me to easyily mount the rotating arm with an 8mm screw.
The length of the arm gives the stroke length, and you have to be able to easily adjust that.
On the end of the arm you need a ball joint. My choice was made for a 8mm threaded rod.
Then you need a shaft joint for connection to the stroking shaft. Also with 8mm holes and set screws.
The bearings for the shaft need to 
be mounted so the joint doesn’t crash
into them whatever stroke length you might choose.
Wish: 186 Nok
This really is the noisy part of this machine. I’ve seen this done with
rails for drawers, which might be better.
Let me know if you find a better way!
As the shafts are 30cm you need to extend them.
My solution was an length extension for drills (100Nok). To fit the shaft I just mounted it on a drill and sanded the end down until it fitted.
Now for the fun part …
The “normal” way to connect the tools are with air tube connectors.
Wish etc are selling sets with these things, and is easy to fit the female end to the shaft with tape etc.
The male part for the air tube 
connector can be mounted on a vac-u-lock adapter or simply a flat plate for suction.
Other Connectors
Hi.
Ive been making my own machine , taking bits of this one and my own ideas. Ive bought the wiper, motor controller and power switch. Im not very electrically minded and im having trouble seeing how its all connected together by the pic. Could you describe what wires go where for me please?
Thanks
Hi!
That depends on what kind of wiper motor you’ve bought.
If it has only 2 wires, they has to be connected to the controller blue and green wires.
(Marked with motor on the controller.)
As this isolated from any electrical ground, it doesn’t matter which goes to which cord.
And on the controller switch, when switching between I and I, the + and – are swapped to the motor to make it rotate the other way.
The powersupply has to be connected +(normaly red) to +(red) on the controller. And -(normaly black) to -(black) on the controller. That should be all…
If your motor has 3 cords you have to look for info on internet, or just test by connecting the motor directly to the powersupply and se how to connect to make it run.
Hope that was what you needed?
Thanks for your reply. The wiper motor i bought has a male connectorwith 5 ‘prongs’. Christ im terrible. Its connected to the wiper by 5 wires. Green red yellow white and black. Unless i can connect to the wiper with a female connector, i’ll probably have to cut and strip the wires from the connector on the wiper and wire it up to the controller?
Hi. I just replied but it hasn’t shown up so hope im not repeating myself here.
The wiper motor ive got has a male connector with 5 wires soldered onto it. Green red black yellow and white. Unless i find a female connector, im guessing i’ll have to cut the wires and connect to the motor. This is all covered in a clear plastic type silicone.
Hi!
Ouch… You need to find out which of the 5 wires to use.
Then you just cut them from the connector and extend them to the controller, or somehow connect just two of them to the exciting connector and test by connecting directly to the power supply.
Something like this: http://www.scarry-terry.com/wipmtr/wipmtr2.htm.
There your would use Common and Low or High speed.
If you have AVO meter, check by Ohm setting that you’re not connecting your PSU to wires that are driectly connected in the motor.
On the adaptor (power supply), do i have to cut the end of to expose the wires in order for me to connect them to the black and red wires on the controller?
Yes.
But get the motor wires figured out before you connect the controller in between.
Test the motor directly to the power supply first..
Hi. Ive got it going now but its slow as hell. Im imagining its the wiper motor?
Ive just noticed actually the power supply is only 4amps. Would 6 make a significant difference?
Its nothing like my power drill machine lol
The wiper is a 12v motor for a nissan. Its incredibly slow even when the controller switch is on maximum
You night have found the slow input wire.
There should be a high speed wire also, or was that even slower?
Oh right ok i’ll try again. I tried putting the wires into a few terminals on the wiper and nothing worked apart from these two connections. Maybe there’s another faster connection. I’ll try it some morel
Hi, I also made my own f-machine, but I used a stepper motor. lm42p.com
This may be a stupid question. But does the rpm = the thrust per minute ???
Revolutions per minute, how many times the motor shaft spins in a minute, and for a good fuck machine you want the motor to spin at least 200 rpm’s
I made a machine using the parts I purchased from a web site called orgasm alley a 120.00 dollar speed control, and a 150.00 dollar motor, I welded my own frame work, it can be adjusted for height, its portable, not to brag or anything but it kicks ass, or should i say well you know it is a fuck machine, if anyone needs parts I recommend orgasm alley, the machine above is very interesting, I may have build a machine that works as good as the top brands out there, but I cant sell them, because they are just to expensive nobody wants to spend that kind of money, no disrespect but i really dont think a wiper motor does the job, my customers have been asking me to build a machine that i can sell cheaper I think i am going to give it a try using this type of motor, but you know that old saying I have to see it to believe it
I’m working on a F Machine using wood and a drill modeled after this design
https://www.youtube.com/watch?v=4kzwMbj-_WI&list=PLjPD2fLiLJtet-KUqoA9jWiPmkrKS7vFI
Although I’ve found that the drill can’t be mounted the same way because there is some play in the chuck which causes a clunk. My idea is to make something that can be made by an average person in their kitchen with minimal tools.
Hi,
I also made my fuck machine. Please check : https://lm42p.com/diy-en/
My f-machine is a manual one, just a rocking chair with a flat metal fold up chair bungee corded of face of rocking chair. Now I can mount any one of my suction cup dildos to the metal chair and back my ass up on it all night long
Hi. A little late since the post publication, I hope someone answer. I want to build my own machine, and I want to know if a fan motor will work? Thanks
Hi,
I would assume, and the author of the post may correct me in this, that any motor can be used as long as it can be controlled in terms of power regulation. I have made other items using motors from fans and washing machines (not kink projects I should add!!) that just required a voltage flow controller to change the speed of the motor.
