With Mark staying to help, we’ve made good progress and have poured the walls of the spring box. This involved operating the mixer/pump for the first time plus some hard labor. So far, so good.
Stages of building the form for the spring box. We started with 2-inch foam insulation walls, then put a rebar web inside that, and finally built plywood wall forms farthest inside. Supports were built inside, and straps over plywood mostly held the exterior. Some additional supports were used on the longer sections of the exterior wall.
Figuring out the pump and lubricating with silicon grease.

looks like good operation!
