hahaha , no , it is no secret , it is relatively simple .
1 take a bowl of water big enough to put your part in.
2 add kitchen salt , to less alt it does not work , too much and they say it does not work also , it does not really matter how
much exactly , you will see if it works or not . stirr it well so the salt is dissolved.
3 take a car battery or charger , i do both , hook the battery to the charger and connect 2 wires to the battery terminals.
4 connect the positive lead to the part you want to etch and connect the negative to a piece of metal , does not really matter , just some kind of strip will do
5 mask off the parts you DON`T want to etch , you can use tape or sticky letters , or even paint ,
6 put your part connected to the positive in the salt water and the strip with the negative also , make sure they do not touch each other
now watch , it begins to bubble and the water turns really dirty , i mean REALLY :-) brown and black with dirty foam and all kind of shit ,
but that is ok , leave the part in for a few minutes , take it out and see how it looks , stainless steel goes really slow but aluminium goes a lot faster so
you will have to watch what it is doing .
what happens is the current goes from positive to negative and takes the material of the part along with it , exept what is under the tape .
hope it is a bit clear , it can not really go wrong
