iImage Information

i found mine in a tape recording machine. I heard that tape machine motors were the standard, but i have also heard of tattoo machines made of nintendo 64 rumble pack motors. When you find your motor, rip it out and take note of the positive and negative wires. Also rip off the stock gear attached to the motor crank. You will be replacing the stock gear with a mechanical pencil eraser fitted to the guitar string needle.
The string is seated off center, On an eraser, Attached to a horizontally mounted motor shaft, Then bent downward towards the tube.
The off center movement of the guitar string forces it up and down.
Just in case someone else cant wrap their brain around how this thing works.
One question i dont see answered in any of these instructibles about tattoo machines is, How deep should the needle penetrate into the skin?
A minimum distance would do for a start position, As I realize skin has different thicknesses, But one setting for all skin types seems possible, And a far sight safer than eyeballing it.
I just dont like the idea of gouging someones muscles, Just to learn how far is too far.
