This is a launching base for a mortar launcher for raquetballs. The base is made of 3/4" ply. It has a range of motion from 45-85 degrees in elevation and 360 degrees field of fire. For competition, degrees will be marked out, and handles will be installed for moving from one range position to another. The launch tube is not modeled in detail (yet), but it is made of easy-to-find parts. The tube itself is made of 2-1/2" schedule 80 PVC. A firing team consists of a loader, launcher, adjuster and a forward controller. Details on the competition will be provided as they develop.
