When the market shifted, he didn\u2019t buy ready-made parts to follow the trend: he relearned his craft differently, through 3D printing. The Coffin Rotary was born from that.\n  <\/p>\n\n  <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/5f655367-3d5a-4c4a-ae42-0c8a1d8c26ae.webp\" alt=\"3D printing workshop for Electric Soul machines in Lancaster, California\" class=\"art-img-full\">\n\n  <p class=\"art-credit\">Photo credit: Electric Soul Tattoo<\/p>\n\n  <h2>A tattoo artist before being a builder<\/h2>\n\n  <p>\n    T Massari has been tattooing since 2003, which is nearly twenty-five years in the business. His studio, Electric Soul Tattoo, opened in Lancaster in 2005, recently celebrated its twentieth anniversary. His tattooing has an American Traditional flavor, but he touches on many styles, with a professed preference for clean pieces and lettering. His guiding principle can be summed up in one sentence: solid lines, and shading that is as smooth and even as possible.\n  <\/p>\n\n  <p>\n    This is important to understand for what follows: Electric Soul is not a brand conceived by a design office. It is equipment designed by someone who tattoos every day, to solve their own problems as a tattoo artist.\n  <\/p>\n\n  <div class=\"art-divider\"><\/div>\n\n  <h2>The era of reels: fifteen years of handmade<\/h2>\n\n  <p>\n    In 2007, T teamed up with Brad Swinson, a seasoned machine builder. Electric Soul Tattoo Machines was born. For about 15 years, the duo sold thousands of handmade 100 % coil machines all over the world.\n  <\/p>\n\n  <p>\n    And \u00abhandmade\u00bb really means handmade: frames cut, milled, welded and ground by hand, binders and reinforcement bars shaped one by one, coil cores cut and coils wound by hand. They even made their own contact screws from copper wire. An obsession with detail inherited from a simple principle, repeated to T since childhood: if you do something, do it to the best of your ability.\n  <\/p>\n\n  <div class=\"art-photos\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/36930e40-b7de-4041-8212-e992eaefb0b6.webp\" alt=\"Batch of the first coil machines manufactured by Electric Soul Tattoo Machines\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/81309e4e-498d-4e5e-a621-f7f35325d6b2.webp\" alt=\"Numbered Electric Soul coil machine\">\n  <\/div>\n\n  <p class=\"art-credit\">Photo credit: Electric Soul Tattoo<\/p>\n\n  <div class=\"art-divider\"><\/div>\n\n  <h2>When the market turns<\/h2>\n\n  <p>\n    Over the years, sales of coil machines slowed down. Many manufacturers then started assembling ready-made parts. T and Brad, for their part, were not comfortable with this idea: their trade was making everything, not assembling. Rather than betray this way of working, they closed the machine workshop. Brad moved to Arkansas.\n  <\/p>\n\n  <p>\n    As for him, he stayed in California. Still behind his machine, always trying to figure out how to do better.\n  <\/p>\n\n  <div class=\"art-divider\"><\/div>\n\n  <h2>The Coffin Rotary: the coil translated into rotary<\/h2>\n\n  <p>\n    The breakthrough came from an annoyance in the field: T was tired of setting up three or four machines for a single piece. A liner, a shader, a mag for color... For every tattoo, the same setup ritual. He tried high-end pens, but many run on a single stroke and their \u00abpancake\u00bb motor lacks the power to pack in heavy lines with a round shader. And he preferred the feel of a tube and grip.\n  <\/p>\n\n  <p>\n    So he got into 3D printing to make the machine he wanted. After fifteen years of coils, the hardest part was done: it was mainly about converting what he liked in a coil into electric motor revolutions. He looked for the right motor, then added an adjustable cam. Result: the Coffin Rotary, and a stroke adjustable by hand from 1 to 5 mm, without tools\u2014whereas most machines are locked into a single stroke, often around 3.6 mm, or cap out at 4.2 mm.\n  <\/p>\n\n  <div class=\"art-photos\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/22b82785-b84d-41f7-9284-8aef069f889d.webp\" alt=\"Electric Soul Coffin Rotary OG machine set\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/e5b6c443-419e-4b20-bf6b-cb7a6c9f91a6.webp\" alt=\"Close-up of the Coffin Rotary Electric Soul rotary machine\">\n  <\/div>\n\n  <p class=\"art-credit\">Photo credit: Electric Soul Tattoo<\/p>\n\n  <p>\n    On the manufacturing side, the Coffin Rotary is printed from a durable material, with a carbon fiber-infused frame and vise. It can be cleaned with disinfecting wipes without fear of damaging the finish, and weighs about 100 grams: making it one of the lightest machines on the market. Its Japanese-brand motor is rated to run up to 30 volts; in everyday use, only a fraction of that is utilized. This is enough to slam in bold lines or pack color, or drop the voltage and stroke for soft lines and very smooth shading.\n  <\/p>\n\n  <div class=\"art-divider\"><\/div>\n\n  <h2>Four models, one same DNA<\/h2>\n\n  <p>\n    The Coffin Rotary comes in four models. The OG is the original version. The C2 adopts a linear armature bar motion and works just as well with cartridges as it does with old-school needle bars\u2014some prefer it precisely for that reason. The C3 completes the range, and T also offers numerous colors as well as custom parts.\n  <\/p>\n\n  <div class=\"art-photos\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/13e342ac-1b5c-4dec-a42c-69a448cb2b28.webp\" alt=\"Machine Coffin Rotary C2 Electric Soul Linear Motion\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/b292f220-b131-4a5e-8e9b-6349e75fba27.webp\" alt=\"Machine Coffin Rotary C3 Electric Soul\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/ae57f470-bd34-468a-bb74-0a59d0f067d6.webp\" alt=\"Set of custom Electric Soul Coffin Rotary tattoo machines in multiple colors\">\n    <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/771463fe-5b5c-49a9-bad5-6de26ef3573c.webp\" alt=\"Machine Coffin Rotary custom colorway watermelon Electric Soul\">\n  <\/div>\n\n  <p class=\"art-credit\">Photo credit: Electric Soul Tattoo<\/p>\n\n  <p>\n    Each machine is printed, inspected, and assembled by T himself.

He also makes his own reinforced RCA cords, adapters, and pedals. Around this, he has developed his own line of consumables: cartridges designed \u00abtrue to needle bar size\u00bb\u2014a needle grouping as sharp as a well-soldered bar, to avoid thin, shaky lines\u2014and grips, manufactured to his specifications.\n  <\/p>\n\n  <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/d7211ce4-c5b1-4076-b96b-c47f6eef983c.webp\" alt=\"Electric Soul cartridges and tips true to needle bar size\" class=\"art-img-inline\">\n\n  <p class=\"art-credit\">Photo credit: Electric Soul Tattoo<\/p>\n\n  <p>\n    The ensemble outlines the coherence of a builder who constructs their entire workstation, from the motor to the needle, rather than an isolated product.\n  <\/p>\n\n  <div class=\"art-divider\"><\/div>\n\n  <h2>Why We&#x27;re Talking About It at Solutat<\/h2>\n\n  <p>\n    Electric Soul is the story of craftsmanship that doesn\u2019t disappear\u2014it transforms. Fifteen years of handmade spools didn\u2019t vanish the day the market changed: they were reinvested in a lightweight, versatile 3D-printed rotary press. This is exactly the kind of continuity that Solutat loves to document\u2014a tradition that is passed down, not a break with the past.\n  <\/p>\n\n  <p>\n    He is also an independent builder who still makes things by hand, in his own workshop. The kind of work that deserves to be seen before it becomes obvious to everyone.\n  <\/p>\n\n  <img decoding=\"async\" src=\"https:\/\/www.solutat.fr\/wp-content\/uploads\/2026\/06\/dc64ab4b-7d1c-491b-ae7a-1ff863ed712d.webp\" alt=\"Electric Soul Tattoo Machines Displays\" class=\"art-img-inline\">\n\n  <div class=\"art-cta\">\n    <p>Electric Soul Tattoo Machines \u2014 T Massari<\/p>\n\n    <span>\n      835 W Ave J, Lancaster, CA 93534 \u00b7 Machines : @estmachines \u00b7 Tattoo : @T_Massari \u00b7 estmachines.com \u00b7 electricsoultattoo.com\n    <\/span>\n\n    <a href=\"https:\/\/www.estmachines.com\" target=\"_blank\" rel=\"noopener\">\n      Discovering one's machines\n\n      <svg viewbox=\"0 0 24 24\">\n        <line x1=\"5\" y1=\"12\" x2=\"19\" y2=\"12\"><\/line>\n        <polyline points=\"12 5 19 12 12 19\"><\/polyline>\n      <\/svg>\n    <\/a>\n  <\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Portrait de builder Electric Soul : quinze ans de bobines, une rotative imprim\u00e9e en 3D Publi\u00e9 par Solutat \u00b7 Portrait de builder \u00c0 Lancaster, en Californie, T Massari a pass\u00e9 une grande partie de sa vie \u00e0 fabriquer des machines \u00e0 bobines \u00e0 la main.
