Hi all I have purchased some rotacastor wheels for 5 dollars a piece. As you can see the wheel on the left I have removed the bearing. I am trying to attach the wheel to the DC motor I have pictured below but I am not mechanically minded. I am trying to not drill into the wheels. If anyone has any ideas how I can do this please let me know.
1. There are a number of alumimun hubs available. 2. Remove the oil/grease and expoy the bearings. 3. 3D print hubs. 4. Bore & turn metal hubs on a lathe. 5. Insert a axle shaft (centered) and fill with plastic.
ggalland and Karel pretty much covered most options. If you have a link to the wheel or can upload a photo, we might be able to see and suggest more options.
