Time for an update that isn't really an update. I've been building a device that will make etching larger pieces easier. I've gone through a few versions in the last month with varying degrees of success. I just finished another one last night, and have sent out some pieces to be made in case the newest version doesn't work the way I want it to. Once significant progress on that has been made, I'll post an update.
As far as this being a sales thread, there is an interest thread within the pages here somewhere, but this has never been a sales thread. I apologize if it was taken that way. I'm just trying to make some wings.
