Berea Hardwoods 19A Bushing is designed to help woodturners achieve precise sizing when crafting pen blanks. These round steel pieces slide onto the mandrel between the mounted pen blanks, allowing you to turn the wood down accurately to the top of the bushing. Each kit includes specific bushings tailored for different mandrels, with the letter following the bushing number indicating the compatible mandrel type, such as A or B. This ensures a fit and smooth turning process for your pen-making projects. Model Number: 19A
