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.
