Walk into any maximum-security yard and you’ll see them. Elaborate sleeves, portraits of lost loved ones, and intricate script that looks like it belongs in a high-end parlor in Los Angeles. But there are no autoclaves here. No professional power supplies. Honestly, the ingenuity behind how to make a tattoo gun in jail is a testament to human creativity, but it’s also a terrifying gamble with infection.
People often think these machines are primitive. They aren't. While the components are scavenged from trash or smuggled electronics, the physics remains the same as a professional rotary machine. It's about converting circular motion into a linear stroke. Basically, if you can find a motor, you can make a mark. But the "how" is only half the story; the "why" and the "what happens after" are where things get heavy.
The Anatomy of a Scavenged Rotary: What Most People Get Wrong
Most people think a jailhouse rig is just a sharpened staple. It’s not. A "staple" job is hand-poked, slow, and often looks like a collection of dots. To get that smooth, professional shading, you need a machine.
The heart of the device is almost always a small DC motor. Think about those tiny motors inside a Sony Walkman or a cheap handheld fan. You've probably seen those clear plastic fans sold in commissaries—those are gold mines. Inmates strip the casing to get to the motor. Then comes the tricky part: the "crank." This is usually a button or a small piece of plastic melted onto the motor's spinning axle. By placing a hole slightly off-center on that button, you create a cam.
That cam is the engine. It pulls the needle up and pushes it down.

For the frame? Anything stiff. A toothbrush is the classic choice. You take a lighter, melt the plastic, and bend it into an "L" shape. The motor is then lashed to the top with rubber bands or stripped electrical wire. It’s shaky. It’s loud. It’s improvised. But it works.
The Needle and the Ink: Where Things Get Dangerous
A professional tattoo needle is surgical steel, tapered to a microscopic point. In prison, the standard is often a guitar string. You’d be surprised how many jails allow acoustic guitars in "recreation" areas. One "E" string can be broken down and sharpened against a concrete floor until it’s fine enough to pierce skin without tearing it.
What they use for "ink"
Professional ink is a suspension of pigments. Prison ink is usually "soot." You take a plastic checker, a rubber shoe sole, or even hair grease, and you burn it. You trap the smoke on a piece of metal or glass, scrape off that fine black carbon, and mix it with a bit of water or, in some cases, clear shampoo.
- Soot ink is permanent.
- It often turns a distinct "prison blue" over time.
- The risk of heavy metal poisoning or dermatitis is massive.
The "pen" part of the machine—the tube that holds the needle—is frequently a hollowed-out Bic pen. You take the ink cartridge out, use the plastic barrel as the guide, and run the sharpened guitar string through it. It’s a tight fit. Too tight, and the motor stalls. Too loose, and the lines look like a shaky earthquake map.

The Hidden Risks Nobody Talks About
We need to talk about the medical reality. Research published in the Journal of Correctional Health Care has long highlighted the correlation between "street" or "prison" tattoos and the transmission of Hepatitis C. Even if a guy uses a "new" needle he sharpened himself, the machine itself is rarely cleaned. Blood aerosols.
The motor, the rubber bands, the porous plastic of the toothbrush—they all soak up microscopic droplets of blood. Since you can't exactly run a toothbrush through a 270-degree autoclave in a cell, the machine becomes a biological time bomb. If the guy three cells down had a "scratch" done with the same motor yesterday, those pathogens are still there.
Why Keyword Still Matters in the Social Hierarchy
In the "feds" or state systems, tattoos are more than just art. They are resumes. They tell people where you’re from, what you’ve done, and who you’re with. This is why the risk is often ignored. Having a high-quality machine makes an inmate a "valuable" asset. A good artist can trade "tats" for commissary, protection, or even drugs.
The process of how to make a tattoo gun in jail is essentially an underground economy. It’s a trade craft passed down from "old heads" to "fish." But the stakes have changed. With the rise of MRSA and more resistant strains of Hep C, the "old school" way is becoming a death sentence for some.

The Evolution of the "Prison Machine"
Modern prison machines have actually gotten "better" in terms of design, even if the safety hasn't caught up. Some inmates have figured out how to use the power supplies from beard trimmers or even scavenged AC adapters to get more consistent voltage. A consistent voltage means a consistent hit.
- The Motor: Usually 1.5v to 3v.
- The Power: Often a series of AA batteries taped together if an outlet isn't available.
- The Needle Bar: Sometimes made from a paperclip if a guitar string isn't available, though the results are much coarser.
The ingenuity is staggering. But it’s important to remember that the legal consequences of being caught with a "sting" (the machine) are severe. It's considered "hazardous contraband." You’re looking at "the hole" (solitary confinement), loss of "good time" credits, and potentially new charges for "possession of a weapon" depending on the warden's mood.
Moving Toward Safer Practices
If you are looking into this because you or someone you know is facing time, the best advice is simple: wait. The risks of permanent scarring, cellulitis, or lifelong viral infections far outweigh the "cool factor" of a jailhouse piece. Professional artists spend years learning about bloodborne pathogens for a reason.
If you're already out and dealing with the aftermath of a prison tattoo, your first step should be a full blood panel. Don't guess. Don't assume you're fine because it "healed okay." Hepatitis C can be asymptomatic for decades while it slowly scars your liver.
For those interested in the technical side of tattooing, focus on the legal route. Modern rotary machines are incredibly affordable and use sterile, disposable cartridges that eliminate 99% of the risks associated with these improvised prison rigs.
Practical Steps for Health and Safety
- Get Tested: Request a Hepatitis C and HIV test if you have any "non-professional" ink.
- Consult a Professional: If a prison tattoo is raised, red, or itchy years later, see a dermatologist; it could be a reaction to the soot ink.
- Laser Removal: Prison ink is often shallow and easier to remove than professional ink, but the scarring underneath may remain.
- Cover-Ups: Always ensure a prison tattoo is fully healed (at least 6 months) before asking a professional artist to cover it with high-quality pigment.
