Throwing arm

Arm has progressed well so far. It consists a two piece vertical lamination of pine to create a 1.5x5.5" cross section (shown in the first photo), then has a 2x6 doubler (second photo) on each side between the wheels and the counterweight hole. Additionally, the last 6" of the center piece has been rotated to minimize the chance of splitting along the counterweight axle. To offset and provide support for the wheels, two pyramid-like supports have been added, as well.  Both of these are visible in the third photograph.
