Sex Machine Building Guide

There are sex toys, and then there are sex machines. And until recently, there have been a few key differences. Sex machines are typically either large floor-standing contraptions or attachments for power tools like reciprocating saws. You can buy them in kits with assembly required, or jury rig them yourself in your garage.

Velvet Co. Thruster Sex Machines

We’re Velvet Co, a boutique sex toy company that designed and manufactures the best quality sex machines in adult land. We weren't new to engineering having owned and operated an advanced aerospace operations in Austin, Texas for more than 23 years. After the sale of that company we decided to do something more fun and less intimated than airplane and rocket parts, The Thruster was the first of its kind, a powerful vibrating thruster in a handheld cordless sex toy.  The sex-tech for this is new and patented, the batteries to drive this much power didn't exist until 10 years ago.

If you enjoy penetration and vaginal orgasm, you'll love the Thruster. And if you’re still set on building your own sex machine, here’s how you’ll want to do it.


Set Your Budget

Before ordering all the materials and learning the steps on how to build your sex machine, it’s important to set a budget. Generally, you can spend as little as $200 for a low-end machine and up to $20,000 if you are looking to build a high-performance machine.

  • Materials You'll Need

One of the first steps you’ll need to figure out when learning how to build sex machines is the materials and parts you’ll use. There are a few basic materials you’ll need, which are available online through retailers like Amazon and 80/20. If this is your first time building a sex machine, you may want to look at a few tutorials to get some inspiration. Depending on the design and performance, you can choose higher quality materials. The following materials will allow you to decide on how performant or stylistic you want your machine to be:

  • Motor  for Sex Machine

This is usually the most costly part of the machine, but also the most important part of learning how to build a sex machine. Look for motors with an RPM between 250 and 350. The higher the RPM, the faster the penetration.
  • Flywheel

This is the part that converts the rotation from the motor into a back-and-forth movement used for penetration. By drilling some holes at various distances from the center of the flywheel, you can adjust the amount of thrust. Depending on the size of the flywheel and where you drill the holes, you can change the amount of thrust, anywhere from 1.5 inches to 6 inches.
  • Pushrods and Bearings

These are the thrusting mechanism, and where you would connect your dildo, vibrator, or thruster. We suggest using an aluminum rod and dust-free bearings because they are less noisy and provide plenty of stability.
  • Penetrating Device

This step is one of the most fun when learning how to build a sex machine. You can choose to attach a dildo to the end of the pushrod or you can add some fittings that allow you to use a set of interchangeable dildos. If you have a dildo, fleshlight, or vibrator, you may opt to add connectors so that you can easily swap one sex toy for the other.Assembling the Sex Machine

Now that you know the different parts you’ll need, let’s dive a little deeper into how to build your sex machine. To save money, you can purchase the essential materials we’ve listed from an online retailer. You can then get the more basic nut and bolt pieces from a local hardware store.

Assembling these parts is rather easy and only requires basic hardware tools including wrenches, screwdrivers, and an electric drill (if you plan on drilling holes through the flywheel).

Alternatives to DIY Sex Machines


If you’re not ready yet to learn how to build a sex machine entirely on your own, or are looking for a more convenient alternative, handheld thrusters may be a good option. Recently, a few advanced handheld thrusters have come to market which deliver up to three inches of thrust and 140 strokes per minute. Velvet Co.’s Classic Thrusters are similar to sex machines in the amount of thrusting power they deliver, yet are battery-powered, allowing you to conveniently them anywhere.
