    Thanks. Looks good.

    Would the process you describe eat away MHS threads? If I were to submerge lets say an MHS 4" double female extension, I would need to vinyl tape the exposes threads correct?
    Could this etching process be used to create a weathered hilt? Use the same process of painting, only instead of a stencil, use an etcher to create marks and wear points.

    The threads on the MHS double female extension are internal, not external. Therefore if they were not covered there would be minimal to no etching. However to be on the safe side, I recommend that they be taped up. For tubular parts that are to be completely submerged, I tape up the inside of the parts. To do this, I cut a strip of vinyl tape, longer than the part and with one end stuck to the bottom of a fingertip, drop it through the part until it sticks out the other side. I then grab the other end of the tape with my other hand and stick it to the inside of the part. Do this until the entire part is covered on the inside. NOTE: For the very first piece of tape, I usually stick a wire to it (the positive lead for etching) with a decent amount of the wire exposed from it's protective sheath so that the bare wire touches the metal of the inside of the tube. Once the part is all taped up with the wire sticking out from one end, I stick a little piece of duct tape on the inside of the tube, over the part where the wire is (near the end where the wire exits the part) and then add some hot glue around where the wire exits the part. This helps to keep water from getting under the tape. Some water will probably get under the tape where the wire is anyways but won't etch the part.

    Yes, this process can be used to weather a hilt but it will be more of a "eaten away"/pitted look and as such may more resemble a saber that has been under water for several years. Remember when making your "marks" that only bare metal gets etched.

    Just saw an Instructable on heatless toner transfer for PCB etching. I wonder if it would work on aluminum as well as copper.

    I use a heated method of toner transfer and it works great for tubular metal, not so great for flat. I'm not sure how well the heatless method works but it's definitely worth looking into, especially if it helps with toner transfer to flat metal. Thanks for the link.

    I'm trying this out for the first time and curious. Could I use my spare TCSS smart charger at 7 volts for this application in leiu of a d cell battery holder?

    I have no idea how your smart charger will react to being used as a power supply. I doubt you'll damage the charger, but you may get poor results with the etching.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

    That's a good way to trip your breakers.

    From what I've read/watched, a lot of battery chargers won't work for etching because they don't get the right current draw and the full battery/protection circuits shut down.

    I use an old 6V/12V car battery charger set to 6V. It trips all the time but resets after a few seconds on it's own so I can walk away and it will still do the job. A lot of the newer ones however will trip and stay that way until you unplug it and plug it back in. If your TCSS smart charger doesn't work, you can always Google PCB etching and you'll eventually find info on a current model of car battery charger that will work.
