thrower's circle form

Abstract

A form for constructing a thrower's circle includes a pair of half sections. Each half section has an upper surface and a base surface and two full length members and two half length members. The full length members and the half length members are connected together substantially at right angles to form a rectangle with four corners. A corner brace is located in each of the four corners. An inside cross member and an outside cross member extend between the half length members and are generally parallel to the full length members. A pair of semi-circles, each having substantially the same diameter that is larger than the length of the half length members and less than the length of the full length members. Means are provided for securing the half sections together so that the semi-circles form a full circle. Tubes extend from the circle toward the base to drain water from with in the circle.
