I Built An Automatic Walnut Bracelet Polishing Machine

The follow-up to my power drill walnut bracelet experiment is finally here. Last time, I attached sandpaper to a spinning disc and built my own automatic bracelet polishing machine. The first stage worked pretty well, but grinding the walnuts created a ton of dust and made everything pretty messy. So for stage two, I switched to a wool polishing pad and let it run for several things. Today, let's see how it turned out. It took three battery changes to get this far. Let's stop the drill and take the bracelet out to see what happened. Not bad, it's definitely much smoother than before, but there's still one problem. The grooves and tiny gaps in the walnuts aren't smooth enough. Looks like we need to move on to an even finer polishing stage using polishing powder. I sprinkled the powder directly onto the bracelet, secured the drill with a clamp just like before and let it polish automatically. We'll leave it running for a full day and come back tomorrow to see how much smoother it gets.
