i can make a homemade tattoo gun but the only problem is with connecting the needle to the motor i use an eraser then the needle keeps shredding the eraser
Take the guitar string and bend a little bit of the end down or up.
File down the brass tip of the pen to get the ball out, make the hole big enough to allow passage of the needle.
Insert the needle into the pen.
Take the tooth brush and cut off the bristles making it about 4" long. Heat it up in the middle with a lighter and bend it in to a "7" and hold in place untill stiff.
Join/tape the pen needle assembly to the tooth brush.
Take the eraser from the pencil and shove it onto the shaft of the motor, try to get it as dead center as possible. Join the pen/needle/tooth brush to the motor/eraser assembly, tape the brush to the motor.
Take the bent part of the needle/guitar stirng and stick it into the eraser (Important - the needle must be purposely off center).
Find a power source. You could hook up some batteries to a switch and then to the contacts of the motor.
Tips
Tattoo ink can be made from paper ashes mixed with some water to thicken it. Use at your own risk! Your best bet is to use pelicans black ink or talens black india ink.
Warnings
You risk blood poisoning unless you use proper tattoo ink.
If you share the tattoo gun, you risk hepatitis, HIV, etc.
Tattoos are for life, so it is best to get them done professionally or you may regret it.
You could electrocute yourself.
Things You'll Need
bic pen (this is your tube that houses the smallest needle.
toothbrush (this gets bent like a "7" and joins the pen to the motor)
an eraser from a pencil (this joins the shaft of the motor to the needle/guitar string)
small battery operated motor (from a "walkman" or a hand held fan)
