It Ain’t Just A Drill: HANDS-ON! Getting the Most Out Of Your Flex Shaft
Instructor: Andy Cooperman
September 26 and 27, Saturday and Sunday, 10am - 3pm
Class Fee: $350 | $30 Materials Kit Fee

So, you're a jeweler or metalsmith about to be stranded on a desert island (for some inexplicable reason this island has, along with coconuts, electricity).  You can bring only one tool. What tool do you bring?

If you were Andy Cooperman you’d most likely bring your Flexible Shaft Machine.  Maybe the most versatile tool at the bench this champion of rotary tools is, for many, underutilized and poorly understood.

Here’s your chance to gain a deeper understanding of this marvelous tool and expand your vocabulary of flexible shaft techniques and applications.  This two-day version of the demo-only workshop will cover the basic machine itself--from the motor, down the shaft to the speed control and handpiece-- and will discuss and demonstrate the use of burrs, bits, grinding, shaping, finishing and polishing aids: the stuff they didn’t teach you in school.

It Ain’t Just A Drill HANDS-ON  is a mix of demonstration and real-time experience, so expect to get your hands dirty exploring some of the techniques and tools addressed --and some eye-opening innovative tricks as well.

Please note: This is a sample-style class. While students will try many of the tools and techniques discussed, we will not be making a complete project.

Students MUST Bring:

  • Couple small drill bits, approximately 1mm or .8mm #58 or #67, size is not critical (available in studio store)
  • SCREW Mandrels 2 or 3, 3/32” (available in studio store)
  • SPLIT Mandrel, 3/32” (available in studio store)
  • 1/2” coil of UNCUT jump rings, 18-22ga any metal
  • Dust mask
  • Any item, project or sample that they are having trouble with that they feel the flex shaft might help with
  • Please prepare a simple “T” seam from copper or brass sheet, any thickness that you have from 22-18ga. The base could be say 1” x 3” and the perpendicular element could be a strip of maybe ½” X the length of the bottom. Please don’t clean it up! Pickle is fine. And do NOT worry about how good the seam is…!

Students MAY Bring:

(most of these items are available to borrow from the studio or purchase in the studio store)

  • Although we will have plenty of Flex Shafts on hand, feel free to bring your own if you are curious about something particular to your machine.
  • This is a great opportunity for students to bring any attachments or “extensions” (my term) that they are in some way mystified or confounded by or are unsure of how to use. These might be:
    • bits, burs, grinders
    • sanders, polishers, wheels, etc.
    • hand pieces, foot pedals, etc.
  • TAPERED punch a like center punch (round x section)
