Time to wrap up the build thread. The only think I had left was turf and after a few days, a few beers, and a few curses, that is done too.
I went with heavy foam on the bottom and in the footholds.
If I had it to do over again, I would go thinner. The extra padding is not really necessary and it just adds a ton of bulk.
Turf was black molded. It does not look as cool as the cut stuff but it is way more durable and I don't really want to do it again. I try to wrap the sides in one piece all the way into the footholds. This can be done if you have a lot of heat and patience. Notch the turf before wrapping it into the foothold.
And the only seam is under the foothold.
And the finished Product.
