Compare actual work done to Task1
Bought two 48 inch wood rods and cut them into 5 1 foot sections. Then I cut a v shape into the end of each rod. Then, starting at 7(1/2) inch mark i drilled a small hole every half an inch up to 11 inches. I then cut a small piece of wood from a cabob into 1/2 and inch segments. I placed one of these segments into each of the holes

Week1 Peer Review
This week we mostly brain stormed ideas. Zach had good ideas for the firing mechanism.

Compare actual work done to Task2
Completed the barrel of the gun. Added Two wooden disks and put the wood rods throught the holes. Sanded down u shaped grooves at the end of the circle so rubber band would fit propely

Week2 Narrative
I finished making both the disks and drilling the holes. I had trouble making the disks perfectly circular and one of the holes is not perfectly aligned. I used a saw to cut out the circles. I also cut a u shape into the end or the circle where the barrels are to make it easy for the rubber bands to slide off. I used a sander to do this with a o shaped sanding bit.

Week2 Peer Review
They helped me build the gun barrel and helped come up with ideas of how to make it the disks.

Assign Task3
Make the device to hold the barrel and find a good motor to spin the barrel.
