Hello, all! New to the engraving world. Brand New. I'm intrigued by the processes and machinery, and overall, I am just tired of paying for a process I would love to learn how to accomplish. My overall goal is etching firearm barrels, but if I have to work my way up from PVC, I get it! So be it. ;) Thanks in advance for all the guidance you are going to offer! My apologies in advance for all the questions I'm about to have!
