Walt that looks awesome, definitely does not look home made and also makes a great mark, very impressive!
I understand a good amount of electronics, but like Ray... I just copped out and bought an etch-o-matic, it works good when I take the time and do it carefully, but honestly it's still one of the most nerve racking things about knife making for me. Maybe because it's the last step on a finished knife that I could easily ruin a finished product in a matter of seconds. |

Lourival,
Walt hasn't posted anything in about two months so he may not respond to your request. However, plans for building a simple etcher are common on the internet and a Google search should find one for you. I realize you're in Brazil and that might make a difference but over here it often is cheaper to buy an Etch-O-Matic than it is to build your own. Walt/Wynn, Etching is the last thing i do too but I never break a sweat over it. The key, for me anyway, is to Scotch tape the stencil to the blade and then add extra tape if required around the stencil to make absolutely sure that the etching pad cannot touch anything but the stencil. If you do that you can't really screw things up. If there is any doubt about the etch, just peel up one corner and look to see that the etch worked. If it didn't, probably due to bad electrical contact, you can put the corner of the stencil back down and try again. As long as you don't lift the stencil too much you won't lose alignment .... |

Walt,
A tip from one electronics guy to another... Put a coil of about 1ft of 16 AWG Nichrome or Kanthal in series with one of your leads. This will be about 1 ohm. Wire an LED, so that it's in the same direction as the current flow when on DC/Etch, across the coil. The LED will illuminates when good current is flowing through the steel and electrolyte. The coil will reduce the available current slightly, but 1 ohm in series has never hurt my etching. I am pulling about 4A and 4V appears across the coil, about right to light the LED. Cheers!
