What Makes These Tattoo Machines Feel Different?
“[19:23] This all comes down to the machine engineering and design and how efficient the mechanism is that's in there, because there's always going to be losses when you have bearings and other mechanisms put between the motor and the needle”
— Aaron Williams
The most commonly considered factor determining how hard a rotary hits is the voltage applied to the motor, but that’s not the only variable. In the video above Aaron describes how power delivery to a tattoo machine is affected by the engineering or the "mechanism" the machine is using.
The more features or points of contact you add between the motor and the needle, the more work or friction is created. Therefore, you have potential loss and a reduction in power.
