The machine building class was a very unique, hands-on experience. And with new technology coming out all the time for modern tattoo artists, it was a nice refreshing way to turn back the clocks a bit and really appreciate how far the industry has come. From learning proper wiring and all the fine tuning it takes to make a machine run properly for the job at hand, I took away a new appreciation for all the artists before us and the machine builders who are still working on their craft to this day.
