A LITTLE BACKGROUND

Hello, my name is T Massari. I started tattooing in 2003 and have put my heart and soul into the tattoo industry since my first outline. I have been an artist my entire life with years of art lessons under my belt, I am a very hand-made art style driven person. As a young child I have had it instilled into me if you're going to do it, do it to the absolute best of your personal ability. if you're doing it make it worth you're time.

In 2007 I teamed up with an extremely talented and seasoned machinist, Brad Swinson. Electric Soul Tattoo Machines were born. Since 2007 we have strived to perfect our jigs we build with, our geometry and our process. Every machine has been and always will be hand-made and personally built by me. This is a huge passion of mine and I dedicate a lot of my life to it. Me and Brad sold thousands of 100% hand-made Coil Tattoo Machines all over the world for about 15 years. Hand cut, milled, welded and grinded frames, hand spun binders and armature bars, hand cut coil cores, hand wound coils. We even made our own contact screws from copper ground wire. Unfortunately Coil Machine sales softened too much to continue making everything by hand. We were not comfortable buying parts like most of the builders today and just simply building, so we closed the doors on the machine shop and Brad moved to a beautiful property in Arkansas and couldn't be happier.

I am still here in California still tattooing and always trying to innovate. I was super tired of setting up 3 or 4 or even more machines to do the style of tattoo work I do. I like a 3RL, 14RS liner, 13M and maybe a 23M, sometimes more depending on the piece. I tried a few high quality pens and they are one stroke and even if they are changeable the often don't have the power to slam in the fat RS lines due to their pancake motor style. Also the pens were not as comfortable for me as a tube and grip. I started messing around with 3D printing to develop something I can personally use and save time and set up hassle and costs of setting up 4 machines. I built coils for 15 years so it wasn't much more than a little conversion math from what I loved about coils into revolutions for the electric motor. Then math sourced and surfaced the perfect motor! I put an adjustable cam on it for obvious reasons. Most machines I see on the market are one stroke, usually around 3.6 (right up the middle), or they need tools or parts to change the stroke. If they are adjustable they often only go to 4.2 max stroke. Coffin Rotary has a 1 - 5 MM "Finger Adjustable" Stroke, no tools needed like most adjustable cams. That big of an adjustable cam paired with the PERFECT Japanese branded motor AND excellent geometry from decades of experience produced a straight up winner. Wait until you try it. I made one for myself, lined at 3.6 Stroke w a 3RL, then switched to 4.6 Stroke and lined with a 9RS, then switched to 4 Stroke and did some color work with a 13M. It lines better than most coils and as good as any I have used and/or made.

The Coffin Rotary is made from a space age material that is both tough and durable. The frame and tube vice is Carbon Fiber infused! These machines can completely be wiped down with your choice of disinfectant wipes to clean with no worry of damaging the finish. Being 3D Printed the Coffin Rotary is probably the lightest machine you will find on the market, right around 100 grams! Don't let that fool you though, the motor is capable of running consistently at 30 volts. We aren't even tapping into 1/3 of the motors potential, you will slam in huge lines like butter and pack color instantly. Turn the voltage down and run ultra consistent soft lines and ultra smooth shading.

I vigorously print, inspect and build each of these machines personally. I put my heart into each and every one and I have no doubt you will see it. I am very much a perfectionist and I always have a large inventory on stock of all colors.

I now have two shipping options. Super fast USPS Priority 1-3 Business Day, or USPS Ground Advantage 3-5 Business Day. You will have options on the Shipping Dropdown menu when you check out. If your priority shipping is more than $20, click the $20 flat rate Priority Shipping box to save some dough. If your Ground Shipping is over $12, click the $12 Flat Rate to save some more dough! I try and ship daily. When your machine ships you will get a tracking number emailed to you. Please check your Junk folder!

MACHINE MODELS AND SUPPLIES

Do the Coffin Rotary Machines have a warranty?

Yes! 1 year full warranty on workmanship and parts. If anything is acting funny give me a shout on IG @Estmachines or an email T@ElectricSoulTattoo.com and we will figure it out! Disassembling or tempering with the machine will void the warranty.
Do Electric Soul Tattoo Cartridges fit any machine?

EST Cartridges are a standard size and fit. They should fit into all the 'pen' style machines as well as any standard cartridge grip.
Are the Coffin Rotary Machines good for smooth greys?

Yes! All 4 models come with a large high-torque motor and a finger adjustable 1-5MM Stroke. You can simply lower the stroke and volts (I love doing black and grey at 2.9MM). On the contrary you can turn the stroke and volts up and easily lay in huge outlines or pack color with huge mags.
Do your machines work with both Cartridges and Needle Bars?

Yes! You can use the OG or the C2 for needle bars or cartridges. Some prefer the C2 for needle cartridges because of the linear movement of the armature bar but both will work great.
Do you have different shipping options?

Yes, I offer the USPS Priority 2-3 day shipping and USPS Ground 5-6 day shipping on all products.
Are your cartridges really stabile and what does true to needle bar size mean?

EST Cartridges have the best 2 part stabilization system in them currently on the market. All of the carts have long thin clear tips so you can easily read where you needle is at. True to needle bar sized grouping means these cartridges have the same grouped needles as a well soldered needle bar. When you get a 5RL from me it will lay perfect 5RL lines, not the skinny wobbly lines that most cartridges offer. Same with the 7's and 9's. No more skinny wobbly lines and no more having to upsize your needle size to get a decent line.
Do you make all your own products?

I 3D Print hand make all 4 models of the Coffin Rotary Tattoo Machines, Heavy Duty RCA Cords, Adapters and Foot Pedals. I outsource the Cartridges and Grips to be made to my specifications.
Do you tattoo too or just make supplies?

I have been a tattoo artist going on 25 years. My tattoo shop Electric Soul Tattoo in Lancaster CA is 20 years old in 2025. I have been hand making tattoo machines since 2008.
