Sex machines are very expensive so it may be tempting to build your own. But you need to be aware that it comes with many risks unless you have experience with material safety and assembly. In the end, you may not even save money since even homemade alternatives can be quite expensive.
Instead, we recommend purchasing a reliable and reasonably priced product like the Velvet Thruster Mini Teddy, which you can buy for only $159. However, if online or physical sex shops are inaccessible to you, we have compiled a list of some semi-safe options below that you can try at your own risk.
- Building a sex machine is a dangerous endeavor and you may end up in the emergency room. Instead, we recommend buying a professionally designed and extensively tested product. Going this route ensures a higher level of safety and provides access to unique features such as thrusting mechanisms, G-thrust attachments, powerful motors, and even smartphone apps.
- If you still insist on making a fuck machine, there are some semi-safe options we discuss below. These methods include a dildo chair and a motorized flywheel. But please note that they still carry significant risks.

What Is A Homemade Sex Machine?
Homemade sex machines are thrusting sex toys that people build using various household items. They are designed to provide sexual pleasure through mechanical stimulation with some accessories like dildos, air tube connectors, and Vac-U-Lock attachments. People build them from various materials, including wood, metal, and plastic, and they typically consist of a motor, a speed controller, and a power supply.
The designs can vary widely, from simple to complex. Some are designed to mimic the motion of sexual intercourse, while others provide more intense stimulation. The material used in the construction will also play an important role in the assembly and measurements. You can make adjustments to the shafts, bolts, and screws to achieve the angles of the strokes you want to achieve.
The motor is the heart of the machine, providing the power necessary to drive the mechanism. The type of motor used will depend on the design and the desired level of power. A high-powered motor will provide more intense stimulation, while a lower-powered motor will provide a gentler experience.
Finally, the speed controller is used to adjust the speed of the motor, allowing the user to control the intensity of the stimulation. A simple controller can be built from a potentiometer and a few other components, while more complex controllers can be purchased or built from scratch.
Is Making a Homemade Fuck Machine Safe?
No. Unless you’re a DIY sex toy expert by profession, building a sex machine is not safe. The building process takes a lot of knowledge, components, and precautions to be considered usable. Here are just a few considerations you must take if you plan to make one from scratch:
Parts and Tools
One of the most important considerations is the quality of the parts. We need to make sure we are only using high-quality parts designed for the purpose because low-quality parts can result in something unsafe for human use.
Frame and Shaft Joint
The frame and shaft joint are also very important. We must ensure that the frame is sturdy and can support the weight of both the individual and the machine. The joints must also be strong and secure to ensure that the machine does not come apart during use. Other options include any available ball joint. Adding a ball joint is important because it connects the control arms to the steering knuckles, and is used on virtually every automobile made.
Motor and Speed Controller
The motor and controller for speed are other critical components. Therefore, we need to ensure we are using a motor powerful enough to provide the desired level of stimulation but not so powerful that it poses a risk. The controller also needs to be easy to use and provide a range of speeds to allow for customization.
Safety Precautions
In addition to using high-quality parts and ensuring that the air tube connectors, Vac-U-Loc attachments, frame, joints, motor, and controller are safe, there are other precautions that we need to keep in mind when using a sex machine. This includes making sure we are using it in a safe and comfortable position, and we need to be aware of any potential hazards that could arise during use.
Note: The most budget option is to buy Mini Teddy, the most affordable sex machine we found during our testing. Our testers praised the thruster’s ease of use, beginner-friendly tapered design, suction cup base, intuitive 2-button interface, multiple thrusting speeds, and realistic detailing. If you want something similar, make sure to check other thrusting dildos right here.
If you really want to go down the DIY route, it may be better to build a homemade Sybian since it’s slightly easier.
Some Semi-Safe Ideas
This chapter has a few semi-safe sex machine plans for those who want to experiment with making their own. However, these methods still come with a lot of risk and we only recommend them for people with extensive knowledge about DIY projects. If you’re unsure about anything below, please buy a professional product ASAP!

- 1x12x8 lumber (1 piece)
- 2ftx4ft 1/2 inch plywood or MDF board
- 2-inch foam padding
- Vinyl fabric
- Stain of choice
- Hardware: 20 eye bolts, 2 O-rings with mounting brackets, 2 pairs of door hinges, 4 sets of 3-inch bolts with nuts and washers, and a box of 1.75-2-inch wood screws.
Tools Needed:
- Table saw
- Miter saw
- Sander
- Drill/driver
Step-by-step Instructions:
- Cut the 2×4 lumber into six 16-inch pieces (consider using 12-14 inches instead) and miter cut the ends at a 45-degree angle. Assemble these pieces into a U-shape for the legs, leaving the top open for attaching the 1/2-inch plywood rest and padding.
- Cut two pieces of 2×4 lumber to 11 inches in length.
- Cut another piece of 2×4 lumber to 48 inches in length.
- Cut the 1x12x8 lumber to 5 feet in length. Cut the remaining 3 feet in half to create two pieces measuring 1x6x36 inches. Use these pieces as the side arms. Attach the 48-inch piece of 2×4 lumber perpendicular along the back of the 1x12x5 board, and then attach the side arms to the front of that piece on either side.
- Attach the two 2x4x11-inch pieces at the base and 14 inches from the bottom using nuts and bolts.
- Cut the 1/2-inch plywood into two pieces measuring 6×16 inches. Attach these pieces to the top of the legs to create a square shape.
- Attach each square to the front 2x4s using door hinges.
- Cut four pieces of plywood measuring 6×16 inches and one piece measuring 10×36 inches. Cut the 2-inch foam padding to match these measurements. Cover the foam with vinyl fabric.
- Cut a piece of plywood measuring 3.5×30 inches for the spreader brace at the bottom. Drill holes every 2-3 inches, starting 6 inches off center on both ends.
- Sand the chair and apply the desired stain.
- Attach the padded pieces by drilling through the back with wood screws.
- Attach the desired hardware as desired.
Note: Ensure that all pieces are securely fastened and take necessary precautions for safety during assembly and use.

It’s the best saddle machine we tested, and the reviewers raved about the unique thrust and G-thrust attachments, the powerful motor, the smartphone app, and the camming integration. You can read our complete Motorbunny Buck review here.
2. Motorized Flywheel Fuck Machine #1
A flywheel fuck machine is another option for those who want to experiment with DIY sex machines. This type can be made using a variety of materials, such as bicycle parts or car parts. Let’s see how Redditor WynkenDeWylde put it together:
Materials used:
- Concrete: A mixture of cement, water, aggregates (such as sand and gravel), and additives, used for foundations, walls, and floors.
- Steel: A strong and durable alloy primarily used for structural frameworks, reinforcement bars, and beams.
- Bricks: Rectangular blocks made of clay or concrete, used for walls and pavements.
- Wood: Natural material used for framing, flooring, doors, windows, and decorative purposes.
- Glass: Transparent material used for windows, doors, skylights, and facades.
- Cement: A binder substance combined with other materials, primarily in concrete production.
- Asphalt: A mixture of aggregates and bitumen, used for road construction and surfacing.
- Tiles: Ceramic or stone pieces used to cover floors, walls, and roofs.
- Plaster: A mixture of gypsum, lime, or cement, used for coating walls and ceilings.
- Insulation materials: Such as fiberglass, foam, or mineral wool, are used for thermal and acoustic insulation.
- Aluminum: Lightweight metal used for window frames, facades, and electrical wiring.
- Roofing materials: Including shingles, tiles, metal sheets, or thatch, are used for covering roofs.
- Paint: A protective and decorative coating applied to walls, ceilings, and surfaces.
- Plastics: Used for pipes, electrical conduits, insulation, and various other applications.
- Aggregates: Crushed stones, gravel, sand, and other granular materials used in concrete and road construction.
Step-By-Step Instructions:
- Cut the baseboard to 7 1/2″ wide and the length needed for your linear bearing rails and flywheel diameter, then round up by an inch or two. Cut a board for your linear rods to mount to, leaving about a 1/4 spare on either side. Cut a board for your motor to mount to.
- Cut a hole for your motor and sand the rough edges of your boards.
- Mount your motor into the Motor Board by fitting the motor into the hole and drilling holes for the mounting bracket. Bolt the motor down with machine screws and nuts.
- Make a template of your flywheel and find the exact center point. Use a ruler to divide the template into 8 equal parts and make 3/8″ holes. Poke a hole through the paper at the center point and the center of the measurements around the template, and use the template to transfer marks onto the flywheel.
- Drill the mounting holes into the flywheel with a 3/16″ drillbit and drill the holes for the push rod with a 3/8″ drillbit. Bolt the 8mm hub flange to the flywheel through the 4 3/16″ holes and attach the motor and flywheel to the motor drive shaft.
- Attach the Thrust Cart Board and put the linear rods through the 2 bearings top and bottom while tracing for placement to ensure they are inline and parallel. Attach the 8mm rod brackets to the ends of your 8mm linear rods and lightly snug the set screw.
- Mount the Thrust Rod to the Thrust Cart and attach the Bearing Board to the Base Board.
- Make the pushrod by connecting the push bolt in the outermost 3/8″ hole on your flywheel to the center of the 3/8″ bolt in the U bracket on the thrust cart. Cut the threaded rod to your measurement with an angle grinder metal cutting wheel, and connect the rod and rod end bearing to complete the pushrod.
- Connect the pushrod to the flywheel and thrust cart with the 3/8″ bolts and nuts. Attach the end of the thrust rod adapter by using a 12mm hub flange with set screws and gluing a 4″ PVC pipe end cap to the flange.

4. Electric Reciprocating Saw
An electric reciprocating saw may seem like an unconventional choice for a homemade fucking machine, but hear us out. With the right attachments, this tool can be transformed into a powerful sex machine. However, you must be aware that using a power tool for sexual purposes can be dangerous. Always make sure to use attachments that are specifically designed for sexual use (like this Hismith adapter), and never use attachments that could cause harm.
5. Grab Your Partner
Finally, the best and safest way is to turn your guy (or if he’s already one) into your “fuck machine”. With a little bit of imagination, you go nuts with your own bodies in the bedroom. Whether you’re using your hands, mouth, or other body parts, there are endless possibilities for exploring your sexuality with your partner. Interestingly, your partner is also the best homemade clit sucker you will ever find.
Not Safe at All Ideas
Making a dildo machine is not safe at all, but there are a few ideas that are just the worst. We strongly advise against attempting these ideas, as they can lead to serious injury or harm:
Power Tools
While it may seem like a good idea to use a power tool, it’s not safe at all. You can easily determine if something is too strong just by looking at how powerful the strokes are. And no, the more the better doesn’t apply for a fuck machine. General Rule: You should only build something that has a reasonable amount of power.
Sharp Objects
Using hard, sharp objects for your DIY project is extremely unsafe and strongly discouraged. It should be common sense, but it’s crucial to always remove any sharp objects attached to your device.
Engaging in activities with sharp objects significantly increases the risk of injuries and can lead to emergency room visits. Please prioritize caution and keep this in mind at all times!
Unstable Devices
If you have a gut feeling that a homemade device appears unstable and unsafe, you should trust your instincts because you are probably correct. One wrong move could potentially lead to dangerous situations. To ensure your safety while indulging in any homemade machine, please carefully examine all bolts and joints to ensure that everything is securely fastened and stable. Taking these precautions will help prevent accidents while you satisfy yourself using such devices.
Pro Tip: You can use a non-permanent thread locker (medium/blue) to ensure all screws remain tight.
How to Use a DIY Fuck Machine?
Using a DIY fuck machine can be a thrilling experience, but it’s important to take precautions to ensure a safe and enjoyable experience. Here are some tips on how to use them:
Lubricant
Apply a generous amount of lubricant to both the machine and your genitals as this will help reduce friction and increase pleasure. We recommend using a water-based lubricant because it’s safe for all types of sex toys.
Speed and Stroke Length
You should adjust the speed and length of the strokes to suit your preferences. Start with a slower speed and shorter stroke length, and gradually increase it as you become more comfortable. This will help you avoid discomfort or injury.
Safety
It’s important to ensure that the device is stable and secure before using it. Make sure that all the parts are properly assembled and tightened with a thread locker. Also, be aware of any potential hazards such as sharp edges or loose wires.
Remember that the best course of action is to always test the toy in your bedroom or a table to know if the loose bolts can cause accidents. This way you can also extend the attachments and check the effectiveness of the motors used.

Why Is it Better To Buy A Commercial Sex Machine?
It may be tempting to build your own but we recommend caution with this dangerous approach. Here are several reasons why it is better to invest in a real sex machine instead.
Cost
While building a DIY fucking machine may seem like a cost-effective option, it can actually end up being more expensive in the long run. Purchasing high-quality materials and tools quickly adds up, and if you make a mistake during the process, you may have to start all over again. On the other hand, purchasing a product may seem like a larger investment upfront, but it will likely save you money in the long run by avoiding costly mistakes and repairs.
If you’re in the market for an app-controlled model, the Lovense sex machine (image above) is our recommendation. Unlike anything you’ll see today, it has a double-thrusting design, with synchronized self-thrusting rods on either end.
Time and Resources
Honestly, making a DIY fucking machine can be a time-consuming process since it includes a lot of measurements, joints, nuts, and even a garage or location to do it. Especially if you’re not experienced in woodworking or engineering, buying a real product is the way to do it. Additionally, it may require specialized tools or materials that are not readily available. On the other hand, purchasing branded, professionally-made products online can save you time and resources by providing everything you need in one package.
High-End Features
If you are looking for a model with high-end features, such as app control, multiple speeds, or customizable settings, building your own is not the ideal option. Pre-made products often come with advanced features like a high-quality engine, shafts you can extend, and properly made measurements that are difficult or impossible to replicate at home.
If high-end features are what you seek, the Shockspot Sex Machine got you. Shockspot’s classic dial control simplified handling, and for the technocrats, the software was better, offering more possibilities. You can also save your patterns for later use, a nifty feature that sets it apart from the competition.
While there are building kits available for purchase, they may not provide the same level of quality or functionality as pre-made products. Additionally, they may still require a significant amount of time and effort to assemble.
Frequently Asked Questions (FAQs)
What materials do I need to build my own sex machine?
For the assembly of your DIY sex machine, you will need a motor, a speed controller, a power supply, a frame, and a dildo attachment you will ride. The motor powers the machine, and you can find it at online retailers or local hardware stores. The speed controller allows you to adjust the motor’s speed, while the power supply provides the necessary power. The frame, made of wood or metal, holds the machine together, and the dildo attachment offers stimulation, which can be purchased or made using a drill and PVC pipe.
Can a DIY sex machine be as good as a store-bought one?
No, a homemade machine cannot match the quality and performance of a professionally manufactured one. Store-bought products are designed and tested by experts to provide superior functionality and durability making them the best thing to acquire. While homemade devices offer customization options and may sometimes be more affordable, they often lack the same level of expertise and precision. Unless you have the necessary technical knowledge and skills, we strictly recommend buying a reputable, pre-made device to ensure optimal satisfaction and minimize potential risks.
What are other homemade female toys?
There are various options for homemade sex toys that can heighten female pleasure or be used for vaginal penetration. For instance, if you seek to improve the sensitivity of your vagina, using a pussy pump is your best choice. You can read more about it in our homemade pussy pump guide. In terms of vaginal penetration, we have a homemade dildo guide and anal dildos 101 at home you can read in case they piqued your interest. You can read them by clicking their links respectively.
