Well, I've finished the extension to my little portable table saw so I can cut 8x10 food panels. And I've ordered my tape - at a pretty good price, but I had to buy a whole case (8 rolls).

Next major phase: cut panels, tape edges, and construct the structure in my driveway (practice makes perfect).

If anyone's interested in leveraging my efforts with my own, let me know. I will probably have extra rolls of tape and will be glad to help anyone cut their panels.
