With a DIY sex machine, you can control the speed, the thrust, and the depth of the penetration for the ultimate toe-curling orgasm.

Now that you know what this homemade machine can do for you, let’s discuss the various ways to build one from the comfort of your home.

How To Make A DIY Fucking Machine

The exact process of making a homemade sex machine depends on your preferred device, in terms of power, simplicity, and intended use. Here are some of the most common homemade sex machines and details on how to create them.


Do not be alarmed – no body parts will come off with this type of machine! A fucksaw is an electrical reciprocating saw and to make one, you will need an adapter (drilling saw), a dildo, and a mounting area. Once you have those three items, follow these simple steps.

Cut the sharp end of the drilling saw and attach it to the bottom part of the rubber dildo. Use the holes on the drilling saw to mount it at a preferred height. A fucksaw is a powerful machine; therefore, you need to ensure it is firmly mounted before switching it on. The adapter helps the attached dildo move back and forth, penetrating your inner walls for maximum pleasure. Slowly, turn on the fucksaw and go easy on power, until you are comfortable.


The fun this toy promise is equal to its incredibly punny name drilldo. Unlike fucksaws, drilldos do not have back and forth movement. Instead, a drilldo moves in a circular motion at high speed. Just attach one of your favorite rubber shafts to your power drill and pound away! Drilldos are particularly great for stimulation before actual penetration, and leave a lot of room for imagination.

How To Make a Drilldo

To make a drilldo, you just need a drill and a dildo.

First, you will have to cut the sharp point of the drill. Then, mount your dildo onto the blunt area of the drill, and that is it!! This is one of the easiest homemade sex machines you’ll ever come across, but its satisfaction levels are some of the highest.

PRO TIP: When using this type of sex machine, never get caught up in the moment and push it too far. It is always advisable to start at a low speed as you find your way up at a higher speed.


A jillsaw is a sex machine made from a jigsaw and a dildo. Once a jigsaw is attached to a dildo, it can be used to stimulate sex and enhance penetration. Creating a jillsaw is very simple and straightforward. Like fucksaws and drilldos, you need to attach a dildo or any sex toy of your choice onto the jigsaw, and that is it.

Making A Self-Assembled Sex Machine

Important tools and equipment you need:


A 12V wiper motor is powerful enough to get the job done. It might not be that quiet, but the noise can be taken care of by some background music while in action.

Power Supply

The power supply should match the power of the motor. Aim for a power supply of between 5A and 6A for best results. You need something that’s strong enough to help you achieve an orgasm, but at the same time easy to control.

Speed Controller

The speed of this particular sex machine should be controlled and adjusted depending on your preferences. For the sustainability of the motor, you need a speed controller with 9-60DC volts.


Measurements of the casing or baseboard may vary depending on the motor’s size and power. Additionally, the length of the base depends on the user. It is essential to make the baseboard comfortable for you and your partner before the action begins.

Rod With Vac-U-Lock ­

This rod determines the length of the thrusts. You may adjust the rod depending on the penetration levels you and your partner prefer.

How To Assemble A DIY Fuck Machine

To assemble all these raw parts to come up with a fully functioning DIY fuck machine, you need the following:

  • Screws
  • Nuts
  • Bolts
  • Thread ball joints

When assembling the sex machine, follow these steps:

Step 1

You need an extension of about 0.2 inches for the motor shaft to help mount the rotating arm and a 0.2in screw. You may use a ball joint on the other side of the rotating arm. You will also need a 0.2in screw and a shaft joint to connect the stroking shaft.

Step 2

For the joints to be stable, regardless of the length of stroke, the shaft bearings need to be in place. The joint also needs to be tightly mounted to prevent it from making too much noise when delivering the strokes.

Step 3

Most people would consider air tube connectors to connect all the tools. The male part (dildo) should be connected and mounted on the rod with a vac-U-lock or flat plate.

Step 4

While connecting your body motor and power supply, please understand that they are not all the same. The connectivity of the body motor and power supply varies depending on the brand and type. It would be a great idea to refer to the manufacturer’s manual for further instructions.

How To Make A Simple DIY Sex Machine

To make a simple fucking machine at home, you will need the following tools:

  • Speed controller
  • Delrin
  • Wooden sheet (16″ by 3″) and thickness of ½”
  • Harbor freight drill
  • Aluminum tube (3″ of ¾”)
  • Nuts, screws, bolts, and extra rod parts

Now that you have everything you need to set this up, here’s what you need to do:

Step 1

Make a flywheel from a wooden board by cutting a 4″ radius circle. Make a hole at the center of the circle where the bearing and the motor will be mounted. Make other holes within small intervals in an upward direction.

Step 2

Using the holes in your harbor drill casing, mount the drill. Remember, the flywheel measurements you come up with at the very beginning will determine the height of the drill mount.

Step 3

Mount the center of the flywheel with a threaded hex standoff.

Step 4

For the flywheel to be connected to the male end part, the back of the flywheel should be counter-drilled.

Step 5

Cut linear guides from Delrin block and fit them with a ¾” shaft by drilling a hole in it. The linear guide should have several holes to adjust the height depending on the position and angles, and should also be placed adjacent to the pipe collar.

Motor/Flywheel DIY Sex-Machine

If you decide to settle for this type of fucking machine, you will need some materials, locally available in retail shops and online dealers. These materials will help you choose the type of performance and style your machine should have.


The motor is the most critical part of the assembly process for this fuck machine. A 12V motor is powerful enough to provide the perfect penetration.


A wooden flywheel is perfect; just make sure you drill a hole at the center and other smaller holes right above it within small intervals. These smaller holes will help you adjust the amount and length of the thrusts up to 9 inches. A flywheel provides back and forth thrusts for penetration as the motor rotates.

Penetration Device

A penetration device brings all the fun when building DIY sex toys from home. Here, you may use single or multiple fittings. A single fitting allows you to use a single dildo or male part. A multiple fitting, on the other hand, gives you access to interchangeable dildos or vibrators for your preference.

While using this sex machine with numerous fittings, you can add connectors to easily swap from one sex toy to another. Also, when attaching a penetration device, fucking machines with numerous connectors give you the freedom to choose the type and size of the device.

Pushrods And Bearings

These are basically the dildo adapters where you attach your dildo, vibrator, or any male toy you intend to use when the action begins. Pushrods provide the much-needed thrusts to help the male part penetrate whenever you’re ready. When buying a pushrod or bearings, you should consider those made from aluminum, and a dust-free bearing to avoid too much noise.

Support Bars

These bars will help hold your DIY sex machine in a fixed, stable position to enable constant, uninterrupted thrusts. You do not want constant interference, especially when the penetration device hits the right spot.

Assembling A Flywheel

Make a hole at the center of the flywheel and drill more holes right above the first one. On one side of the flywheel, mount the motor using screws, and on the other side, attach the bearing.

The bearing then connects to the pushrod. At the end of the pushrod, that’s where you connect your dildo.

The support bars should be mounted firmly with screws to support the whole machine from all angles.

Seat Sex Machines

Take a seat and enjoy the ride! This kind of sex machine is very comfortable due to its sitting and riding position. A great and comfortable way to spice up things in the bedroom!

What You Need

  • A wooden chair or stool
  • Drilling saw
  • Penetration devices of your choice
  • Mounting materials such as screws, nuts joints, nails

How To Assemble Seat Fucking Machines

Step 1

Create a strong foundation, preferably from concrete (in your garage, basement, or a private room). The concrete foundation guarantees more stability and stays in a fixed position.

Step 2

Cut off the sharp or pointed edge of the saw to prevent it from drilling through the rubber dildo. Remember to leave enough length to fit your male rubber part (dildo).

Step 3

Connect the male rubber part to the drill saw in an upright position.

Step 4

Drill a hole at the center of the sitting base of the stool or chair. The hole should be big enough to allow the male part to go through it, but don’t make it too big or too tight to enable swift enticing thrusts while you sit on the chair.

The position of the hole varies depending on the size of the user and comfort. Before drilling the hole on the seat, be sure to take measurements by sitting on it. This should help you find the exact spot to cut, based on the position of your honey pot.

Step 5

Place the stool on the drill saw for the dildo to fit the hole you just drilled. This machine is rideable and comfortable enough to give you the pleasure you need. It is also suitable for your female partner while giving a blowjob – the dildo would be working on her inner walls, providing indescribable pleasure.

Before you dash out to make your own homemade fucking machine based on the instructions provided above, there’s another option you may want to consider.

Here’s what to do:

  1. Get a drill of about 24 inches by 9 inches and a speed controller of your choice.
  2. You will also need a flywheel to connect to the drill. The connection will move the rod with the rubber male part or dildo. The size of your flywheel will determine the stroke length.
  3. Connect the speed controller and the drill to the flywheel and the base. The speed controller will determine how hard or soft the penetration and thrust should be.
  4. Connect the pushrod and then add a Vac-U-Lock attachment.
  5. Make sizeable and adjustable linear guides, and then connect your rod to the linear guide base.
  6. Get some privacy, and have fun!

These machines are simple and easy to make from the comfort of your home. They come in different shapes and forms, and it’s up to you to choose the one you feel is more satisfying, comfortable, or easy to complete, depending on your needs and the materials at your disposal.

Homemade sex toys are incredibly reliable and you can use these anytime and for as long as you wish. The best thing about these machines is that they provide you with the opportunity to explore your creativity and come up with something that’s specifically tailored for your own sexual needs. It’s time to try your hand at making your own DIY sex machine!
