I made an arch for an old greenhouse. It supports the metal pipes and extends the frame 2'. Seems to be solid enough. The new cover is 7' x 12' x 7' high. The block base cuts out weed eating. Screening the rock and clay wasn't fun. Once the assembly was complete I removed half the support between the legs. I turned the small tapered pieces for the pipes to slide onto. There are 2 turnbuckles that pull the end pieces together. Hope to have some awesome tomatoes! All the wood is recycled.
