I'm showing you how I made a tattoo gun (and you could)
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)
+ look cool
+ changeable needles
Stuff you will need:
+ a moderate variety of tools
+ metal pipes & plates
+ a strong motor
+ battery pack
Step 1: Planning
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.
