The flexible shaft machine is the metalsmith’s most versatile—and often most underutilized—tool. Whether you’re investing in your very first flex shaft, looking to properly maintain the motor and handpieces you already own, or simply overwhelmed by the dizzying variety of burs, bits, and mandrels available, this OG deep-dive workshop is for you.

Led by professional metalsmith and tool expert Kristin Mitsu Shiga, this class will cover everything you need to know to get the most out of your flex shaft. You’ll learn about motor types, handpiece options, and speed controls recommended for jewelry-making and other small-scale metalwork. Kristin will also share tips on setting up your workstation, choosing the right hanger system, and organizing your burs and bits so they’re always within reach.

The highlight of this definitive workshop is Kristin’s comprehensive demonstration of nearly every type of bur, bit, and mandrel available today for drilling, cutting, grinding, sanding, and polishing—organized from coarsest to finest. You’ll see how each tool performs, when to use it, and how to extend its life with proper lubrication and running speed. Tips for drilling and shaping glass, stones and wood will also be discussed.

Through live demonstrations, a visual slideshow and take-home handouts, you’ll walk away with:

• A clear understanding of the flex shaft’s components and how they work together

• Confidence in maintaining and troubleshooting your machine

• Knowledge of which tools are best suited to your specific processes
