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, posted below, 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 in the video description.

That's beautiful. I am wondering if ball bearings are the way to go as opposed to small pins running in bushings?
I think a traditional pin point on the bottom and a bearing in the top would be the ticket. Ideally, zero axial load on the bearing to reduce friction.

Thank you. For this build since I needed the shaft to come through to use the starter I had to use the ball bearings. Had to find the right ones to make it work but they him just fine now.

That may be worth a try. Can easily make a new shaft and bottom insert to see. May do that when my son brings it home this summer.
