Got an order for 100 migratory covers, day before yesterday. Yesterday I cut them out and assembled 60 of them. Took 2 1/2 hours to cut all of them out, and then about 15 per hour for assembly time. I put together the other 40 today. They are made of lap-joint construction, and ALL contact edges/sides (wood-on-wood) are glued with Titebond 2, for max weather resistance, and are constructed from ponderosa. Anyway, I enjoyed myself! Enjoy the pics.
