Yesterday was one of the last trips to the shop we will be making prior to the competition which will be held on Thursday, December 6th at the College of Engineering Design Expo. We drilled larger holes in the tube stocks to accomodate the flywheel axle bearings. Along with that, our tiny 2.5mm diameter driveshaft bearings came in the mail! However, it turned out that the 0.04mm difference in size between the bearings and the driveshaft (2.54mm diameter) prevented us from fitting the bearings over the driveshaft. Suggestions have been flying around to either file down the driveshaft or leave the driveshaft in a freezer in order to subject it to thermal contraction. We're not sure what implications the freezing would have after the driveshaft warms up, especially since the bearings are very delicate and would most likely break under any sort of pressure.
The only thing left to do now is waterjet the rest of our parts and finish assembling our robot...
