Extensions front and back
by Gene Burch
I removed one of the legs of an old camera tripod, installed the flat bar that came with the T-leg to the bottom extension of the tripod and used a 1/4" 20thread screw to secure the leg to the box after sliding it in the channel in the back. I then attached 1/8" x 1/2" flat aluminum bars to the left and right edges of the wood frame of the box with holes along the bar at 3/4" spacing. Then I made two removable flat bars with three stainless machine screws in each bar about four+" apart so that the screws are in some multiple of 3/4"apart so they can drop into the holes in the box bars. I can then drop these bars into the box bars holes so that they can extend out to support the box when it is tipped forward to catch the earliest sun elevation(like 8 o'clock in February)without the panels hitting the ground. I use a medium sized paper spring clip to keep the bar from working out of the box bar, though I haven't had the bar slip out without the clip. The screw threads seem to provide enough friction to prevent that. The tripod leg then is extended to touch the ground at the rear. I end up with a stable three point contact with the ground, and as the sun rises I shorten the tripod extension, extend the bars to the front until the center of gravity is eventually to the rear of the box and the bars aren't needed for tip prevention.
