building the frame

I decided to build the frame and lens mount with PVC.
Easier and faster to construct. Will post a picture as soon as I get it together.
Considered building it of metal, but until I get all the measurements right, this is a good medium to build prototype.
Frame is in three parts, a base that is stationary to the ground, then a rotational vertical axis to track the sun east to west, and a horizontal axis to track the sun's height above the horizon.
