I'm working on a home made tattoo gun.
It's made with a pneumatic drill, a guitar pick , a bass string , a pen, duct tape and some scrap metal.
And powered by compressed air at 120 p.s.i
Home made ink...
The ink part didn't work.
The prototype was a semi success. It makes clean lines, but they are kind of flesh wounds as apposed to the fine-lined tattoos I'm shooting for.
