So, if you want to get geeky on how to make your own special ring for a special occasion (say, a wedding), then you need to check out this video by triggeron. I’m only slightly familiar with machining, but this guy makes the whole process beyond interesting and educational. The fact that he’s also giving technical information is a really big plus. The fact that he creates tools that he needs to do the job is brilliantly well-rounded (oh look, a little ring pun). Reddit finds/offers the most amazing videos, and once again, they’ve done it with this find! Definitely check out the whole video, because it’s vastly entertaining and looks like fun.
