VaderSpade-
I have a couple questions about the etching process. You mention 'weeding' the stencil. What does that mean? What kind of tape are you using for adhering the stencil and masking off areas? Do you set the charger to the full 12 V when you do this? And finally, do you have a rough measurement ratio on salt to vinegar? Answers The stencil is placed on the receiver with the letters in place. The letters or graphics are then “weeded out”, this makes the stencil easier to place, and gives a solid surface to work against. You will need a magnifying glass (I double up reading glasses) and a long needle to carefully remove (weed) the parts you want etched. The stencils are cut from vinyl designed for sign making; http://www.uscutter.com/GreenStar-In...ll_p_1020.html My charger is set to the full 12 volts @ 10 amps. The amps that trickle through are determined by how much surface area is contacted by the Q-tip. I should say large open areas do not work as well as smaller outlines. I use about ½ cup of vinegar and a teaspoon of salt. |
