This is why I love this community! I checked my tip inbox and found this gem from @jennistuartjewelry on a DIY polishing wheel. “An easy way to make your own polishing wheel using cardboard! Wheels can be made to any size and experiment with types of cardboard to see what finish you get. This is great for flat areas to polish or tight spots. Using stiffer cardboard is typically best.“ The mandrel is a screw type! Thank you Katie for taking the time to create and send this helpful tip. We appreciate you!! #polishingtip #diyjewelrytool #diypolishingtool #polishinggold #goldsmithtip
