Gyroscope Build With Through Shaft, Ceramic Bearings Using A Cordless Rotary Tool To Power It Media
Published: 11 months ago
My son is a physics major and wanted a Gyroscope for Christmas. I merged a couple of designs from @Clickspring to create a bench top style Gyroscope that he could easily power up to speed with a cordless rotary tool. This required a shaft that extended beyond the outer ring to apply power and meant using ceramic roller ball bearings instead of the cone style bearings traditionally used in toy gyroscopes.
I know this video is extra long. My son is ready to learn to do some machining and wants to try making one of these himself. I wanted to give him a complete set of dimensioned drawings as well as a step by step video to complete the project. At the same time, I wanted to ensure everyone could see some machining take place and watch this full build come together. I hope this will help anyone who wants to make a gyroscope and provide enough detail that you can tackle the project.
It took me a couple of tries to find roller bearings that could handle the speed for this build. I finally found them at Boca bearing. Link to the bearings I used here - https://www.bocabearings.com/products/sr3c-2os-7-af2-16312
I did a full design of this gyroscope in Fusion 360 and you can access all of the dimensioned drawings for this gyroscope build on a Hobby-Machinist post here - https://www.hobby-machinist.com/threads/gyroscope-for-christmas.109740/
