Thanks to Jaime Marin for this excellent find. This video shows how to build and use a handmade tube filler to make hyperadobe (raschel mesh) earthbag walls. The machine holds the funnel in place to help fill the tube and then rolls backwards down the wall. Note how they’re not using barbed wire because they’re using mesh, and the project is probably not in an earthquake zone. By the way, always use barbed wire on domes.
