I'm showing you how I made a tattoo gun (and you could)
Story:
A few weeks ago a stoner from school offered me $100 to make him a tattoo gun. At first I was worried to construct a product that could be potentially dangerous and cause permanent damage. But while browsing instructables I saw the gun made by graphak and figured if graphak can make his out of toothbrushes and tape, then I could probably do better.
The outlines for the gun are:
+ it MUST be "stonerproof" (strong & reliable)
+ portable
+ look cool
+ accurate
+ changeable needles
Stuff you will need:
+ a moderate variety of tools
+ metal pipes & plates
+ a strong motor
+ battery pack

Common tattoo guns work off the use of electromagnet coils (patent here) . Since I haven't had much success with coils in the past I have decided to use the rotary method.
As in the use of most rotary tattoo guns there is no mechanism to convert the rotary motion of the motor into a linear motion. To create a more accurate tattooing gun I must create this motion without loosing too much torque through friction.
To do this I plan on having a separate linear mechanism in the shaft connected to the cam through a bent wire. This also allows for a more functional method of changing needles by having an opening in the pipe allowing the user to simply unscrew the needle. As well as creating a much more accurate gun.
The gun must be comfortable to hold and easy to use. I will also try to avoid as much vibration as possible, by counterweights ect.

If I could sugest, humble honest opinion, not trying to be smart, try adding two springs (up un down cam), the one on the bottom of the cam, should be a litle bit strongest, to mantein needdles up, when machine is off, safer. the cam could fit inside a linear bearring, that should take away friction, noise and vibration. You could make a conector to the cam, this conector may be used as an embrague, to adjust the strenght at whitch needles go in, or if to much force applied if starts turning but not pushing the needle. If I may, i might use your idea in an instructuble of my own, my machine :).
the only real way to sterilize tubes for a real tattoo MACHINE is in an autoclave. and needles should only be used once.
