Buttons for Jumbo/Cole Jaws
Sometimes when using my jumbo/Cole-type jaws to finish the bottom of a bowl, I find the standard buttons are not tall enough. Looking around for something else to use,
I noticed synthetic wine corks and decided to try them. I drilled through them on my lathe, held in a set of small spigot jaws. I added some M6-1 × 50mm bolts and the new, longer buttons work super.
I have since discovered a commercial product similar to my idea, but mine uses something that would otherwise be thrown away, is fun to obtain (drink responsibly), and costs about $2. Also, they leave no black or other colored marks on the surface of the wood.
