Aluminum Cannon

By Jim

I found this aluminum cannon I made in a machine shop class at RPI while I was taking pictures of my wood projects.  Machine shop classes often make cannons because they involve the use of many machines & techniques.  The pieces are rough cut on a band saw.  The barrel and wheels are turned on a lathe.  The wheels and pin are knurled on the lathe.  The base is shaped on an end mill, drilled on a drill press, and tapped to accept the machine bolts that hold on the wheels.  The cannon is attached by press-fitting the knurled end of the pin into the base.
