We have only 3 weeks to finish both the car and the testing. Today, we worked on packing up the shop, building the solar panel ground supports, setting up the replacement tire, and working on the electronic circuits for the telemetry.

In case you’re wondering how to set up a replacement tire.

Step 1) Remove the old bearings from the tire using a hammer and chisel. Be sure to move the chisel around the circumference of the bearing so that it doesn’t get stuck.

Step 2) Clean the bearing with WD-40. (which feels like the cheese grease of a pizza)

Step 3) Apply motor grease to the bearing. (The grease reduces the friction of the bearing)

Step 4) Place the bearing in the tire and place a block of wood on top of it. Then, with a hammer, hit the block of wood around the circumference of the bearing. ( the wood prevents the shock of the hammer from damaging the bearing)
