Esshup would the 18" to 24" fish egg areas butt up next to each other or is there a waisted spacing between the 18" to 24" area? If you think there might be then I will just make 18" square surfaces and stack them with probably 4" spacers. This is what I have in mind. I have some alum. siding that's been setting in the pole barn for years.
Dave I should make a model based on the picture and observe it with different size spacings like I am doing on the present model before building a lot of them.
