This wonderfully made tattoo machine weighs 3.8 OUNCES and has a balanced ERGO-design that was designed in such a way that all the weight was mathematically formatted by top engineers to flow with the weight of the tube, thus giving an overall feel of virtual weightlessness. this particular design has helped many artists with wrist pain issues and carpal tunnel syndrome cramps, allowing them to work hours longer than they could have previously. The Bishop Rotary tattoo machine is made using billet aircraft aluminum on state of the art 5 AXIS CNC machines for ultimate precision, then hand polished, insuring tight tolerances and excellent finishes. Each machine is hand assembled to insure precise fit and function. Each Bishop Rotary tattoo machine is anodized to aircraft industry standards, both for finish and ware resistance in friction areas. We only use Swiss made MAXON motors to generate a linear motion of the needle. The Bishop Rotary tattoo machine utilizes a “double sized Needle Clip” eliminating the old standard rubber band to create the down force on the needle. The clip holds the needle in place and eliminates any lateral motion in the needle. This allows the artist to pick away at those ultra fine details! For color packing and shading, run the machine between 7.5 – 8.5 volts depending on your hand speed and style. For lining, run the machines between 8 – 9 volts depending on your hand speed and style. Determine what feels right to you as the artist and remember with anything, its going to take a few tattoos to get used to, so certainly remain using the machine, and like tons of artists you will agree this machine hands down gets tattooing done up to 30% faster due to consistent punctures per second as well as healing 30% faster..
