Asian Ironwood burl yo-yo

Always a pleasure to see what you are up to. Now I guess the tires are so youcan "walk the dog" and not damage the Yo-Yo

Gerald, yes that is correct...a decorative shield of protection. But there is another reason for the rubber o-rings, or at least the channels they sit in. Can you guess what turning related purpose the o-ring channels serve?

I will make a wild guess that you have either a jig or jaws on a chuck to fit the groove.

beautiful Finnish....super

Gerald, yep...that's pretty much it. Here's a quick photo essay on how I do it. After turning the first side, the right-hand channel edge is used as a perfect auto-alignment tool when the piece is flipped to finish the second side. Makes a perfectly balanced yo-yo every time, if your measurements are precise. Dovetail jaws are needed to lock in the flipped piece for side two turning.
