DIY Fuck Machine
I decided to build a fuck machine instead of buying one for the most obvious of reasons, cost. I just have a hard time justifying spending that amount of cash, when I know I can afford to spend the time. Plus, when you build something like this yourself, you also know how to fix it.
I spent a fair amount of time looking at examples of existing ones and thinking about how I would want to use it. I figured the most common use of it would be on the bed, so I designed it with the linear push arm low, close to the surface. I also took into account how a person sinks into the bed. I have the base expand out to protect the spinning of the rocker arm, this also enlarges it’s footprint, giving it traction. I tried to keep the design as compact as possible to make it easy to handle and store.
As I was searching for hardware, I found a pre-assembled unit on Amazon that had most of the hardware I was looking for. It came with the motor, rocker arm and linear push arm mounted to a piece of aluminum angle, it also came with a speed controller. At the time, it seemed like a good deal. I built a wood frame to mount that to and my first fuck machine was up and running.

Well, it did work, but the motor was way underpowered and was really noisy. That got me into research mode and I boned up on DC motor sizes and types.
I ended up settling on a 24V 80W worm gear motor with a max speed of 160RPM and I’m very happy with it. I was able to use the rocker arm and linear arm from my previous purchase so not all was a loss. Another thing I learned about was getting a speed controller that is properly rated for the motor you’re using.

I rebuilt the machine with the new motor and an all wood frame. I replaced the nut that holds the linear actuator to the rocker arm with a wing nut, that makes it much easier to adjust the stroke, which can vary from 2 to 5 inches. It has the torque to start slowly and can go faster than one would want. And it is fairly quiet which is really nice.
We have used wood clamps to mount the machine to stools, countertops, chairs, etc to use it in different positions. And I came up with a foot of sorts that I can use to set it to different angles.

I ended up spending about $200 on this build, more than I wanted, however, with what I learned, I could build another one for about $150, not bad when you consider a decent fuck machine will cost you over $500.
For those interested in building one themselves, I’m working on putting together a project sheet for this, like I made for the Blowjob Machine. It will have pointers and diagrams. I’ll be sharing that here soon.
