The mixing operation.
Polymer modified portland and sand are added to the mixer from 5 gallon buckets and mixed with eps from the large white bag hanging above the mixer.
The lift is made from Superstrut steel from a local big box store. The structure is only lifting about 120 pounds. Last spring I forgot to lower the bag out of the air at the end of the day. A storm came in with sustained winds of 42 mph with gusts of 60. That bag was less than 1/4 full. I just knew I'd find everything on the ground. The next morning I found the bag and structure intact and unmoved. I did test the deflection, weight and did a bit of math before final construction. Gotta learn to trust my math and testing more.
