Shotsie Gorman is a professional tattoo artist, here on behalf of expert village. The tattooing
machines themselves are already set up. It's a very simple system with an oscilating relay,
the needles are soddered onto the end of the bar, that's the needle bar and needle. This
is where we're actually going to start off with a configuration of three point zero twelve
stainless steel solid needles. Unlike syringe needles, tattooing needles are solid. It's
placed down into the tube. The ancient technology of rubber bands is just to give some flexibility
to the needle so that it has the possibility of moving around within the context of that
tube. And the bag, of course, protects it from any cross contamination. Once we step
on the peddle, we're getting the DC current running through the machine which is causing
the coils to magnetize, drawing the armiture bar down, very quickly. And when that circuit
is broken it demagnetizes and then the spring tension draws it back up and it does this
back and forth motion very much in the order of a door bell system or a car point system.
So it's now moving at about three thousand repetitions per minute. Each machine runs
at a different speed, each machine has it's own set of spring tension, depending on what
it's function is, for line work or for color, or using larger configurations. Needles can
go anywhere from one to twenty five for the outline and on the shading I've worked up
to fifty needles in a cluster.
