Right now in class we are building cams. A cam is a type of mechanism. It is able t0 change the direction 0f a rod on top of the cam by turning or moving disks. They are really fun. The tools we needed so far is a ruler, scissors, and a slice cutter. I am working on cutting out all my pieces. In order to cut the pieces in the middle, you use a slice cutter which you hold like a pencil. It has a little blade and you use the blade to cut the pieces out. For the outside pieces, we use scissors. We cut on all the solid lines and fold on all the dotted lines. I am on the second sheet of cam b (each cam has a different resulting action). After I finish cutting, I will fold all my pieces and assemble them to build the cam. This is our first project and I am very excited to keep working on my cam.
