Bearings!!

Today we went to our sponsor Auckland Bearings to get some bearings to see whether they fit into our rods.


Unfortunately due to the little edges on the reinforced steel, which makes an extra 1-2mm bigger than the bearings themselves, we're now resulting to possibly find some rods with a smooth surface.


However, here are some photos of the things we're going to use: 

Rings we might need to use to secure our bearings in its place

Bearings

In order to make our layers spin around, with the least friction possible, we are exploring using bearings for each layer to run along and create our desired motion. 

These are skateboard bearings but could easily be adapted to fit into our mechanism.
