Turkey Day Update

The week leading up to Thanksgiving was a hectic one for the 8th Wonder. This is because MS8 was due yesterday. We had doubts about finishing, but a valiant all night effort and maximizing our time in the shop allowed us to finish 95% of MS8. Our design is really coming along now. We just ordered our last parts today from McMaster-Carr: springs, aluminum bar stock, spacers. Okay, I'm signing off now to eat turkey with family. Enjoy your Thanksgiving!

Update for Week November 15th

This week we worked in the machine shop to complete MS-7. For our three parts we have chosen the top left and right support brackets, the spacer piece for the shovel attachment and the axle rod for our gears. The three types of machines used in the manufacturing of the three parts were, mill, lathe and band saw. We didn't run into any difficulties manufacturing these three parts, but will need to find a way to increase the pace we manufacture parts if we are going to finish MS-8 by Thanksgiving.

Week of November 8

This week we met twice. Once on Monday to update our rack module and once on Thursday to sign up for shop times and finish the motor lab. In our rack module we changed the bracket design that holds the rack. Instead of having two brackets on each side, we now have one on each side. We also eliminated the lower brackets. Instead of having only a sheet metal casing around the rack, we have two nylon bushings inside the bracket allowing for smoother linear motion. Once we cut the nylon bushings to size, we will need to rub the interior of the bushings with acetone, to make them extra smooth.

Week of November 1st

During this week we met on Wednesday, Nov 3. from 9pm-1am to work on MS6. We made revisions to our most critical module, created our bill of materials and began work on engineering drawings. We then met on Thursday, Nov. 4 from 10pm-2am to finish the engineering drawings as well as create the manufacturing list.
