Gears for Makers | Learn How to Design & Make a Gear
Gears for Makers
Hands-on fundamentals of gear design, processing, and inspection!
Course outlines below
1-Day Gears for Makers Class HANDS ON!
Course Fundamentals
This course will cover all of the essentials on how to make a gear: covering specifications, terminology, blanks, machining, reverse engineering and inspection. This completes a loop so you can go from design to inspection insuring your gears will work.
As an introductory course, we'll start from the ground-level basics of precision measurement (calipers, micrometers, and Vernier scales), calculating gear dimensions, gear ratios, loading and operating gear hobbers, and then measure and inspect our finished gears. Tactics for gear milling are also shown. The knowledge is universal and will help your shop with this essential skill for whatever tools you prefer (3D printer, CNC router, Bridgeport mill, etc.)

Real, Hands-On Machining
Get out of the classroom and actually operate the machines needed to make a gear.
Our shop, located in sunny Ventura, CA, has many Pfauter RS00, Mikron 132 and Mikron 79 gear hobbers lined up and ready for training. We use the Pfauter because they are quick, allowing everyone to cut their own gear, measure it, and see it in mesh. Whether you're making a watch or an excavator, hobbing is the go-to process for gear-making. And yes, we do gear milling too, and will show those setups and techniques. Get your gear game on!
Design & Measurement
Whether your shop uses a 3D Printer, CNC Router, Laser Cutter, CNC Mill, or manual machines, the operating principles are the same. We'll cover the fundamentals of change gears, cutting feeds and speeds, and proper setups to ensure in-spec, concentric gears your customers will be happy to receive, and you will be proud to incorporate into your products.
Yes, we cover the math and demonstrate some of the more difficult problems that need to be solved. But we also provide our calculators that solve these tedious math problems. And YES, they are free.
Experience & Reverse Engineering
Use our comprehensive set of templates to find out what the pitch, module and pressure angle is for your gear. Combine it with the calculators and some common sense so that you can cut with confidence next time the need arises.
Each participant will receive a reference packet, access to our suite of online tools, and certificate of completion.
