Quick word on foam. There are several types I used 3/8 Divinycell H80 and H60 on my project a bit cheaper than core-cell and does not need to be heated. I bought full sheets and ripped them to strips then used a router and cut it with a “canoe bit” which has a combo bead and cove blade. There are two main thoughts on foam stripping horizontal or vertical, the farrier guys like the vertical method. It looks like a good method - but did not work with my design. I used the older horizontal method. Gorilla glue worked good to glue the strips together and fares out well.
