MASSIVE-ANT: Drilled/Tapped Motor Mount Holes, Disassembled Nerf Gun, Filed Burrs, Cut Side Rails, Cut Shelf, Chassis Reassembly

Friday 4/4

Matt came in late due to a meeting. After the screw holes were drilled, Matt tapped the holes to create threads for screws/bolts; this would also eliminate the need for nuts. Since we chamfered the side rails, the shelf needed to be cut or bent so it wouldn't drag on the ground or curb. We decided to just cut it to the size of the bottom side rail edge. He then measured and marked the locations of the shelf cuts to allow for the motors. With help from Patrick, he drilled holes to attach the shelf to the side rails. We then put the chassis back together and mounted the motors.

Since Mike had experience with the drill press, he drilled the motor mount screw holes. To help Shela 2.0 mount curbs better, we decided to make the front part of the chassis angled and to shorten the back end so the motor mounts were flush with the edge. We decided angle of roughly 20-30 degrees would work best. After measuring and marking the cuts we wanted, he cut the side rails and shelf, using the sawzall and hacksaw.

To save time and get multiple things done at once, I did Mike's task of disassembling the nerf gun. I got it most of the way but it just wouldn't budge without breaking. I eventually got it apart though. The shelf needed to have room for the motors but the sides of the shelf had to have a notch cut or something to allow for this. With some help from Matt and Mike, I decided to just cut the sides away where the motors would be. Once all cuts were made, I filed the burrs. To ensure the top idlers cogs would be free spinning (not have the axle move, just the cogs) we connected the two axles together. This is not very good and we will have to make something better.
