Here's an image of the barrel handler.
Short session today, but got some progress. I installed the side wall and got the flooring started for the 2nd Level Side Aisle Flooring. Once the joists were installed the long wall got much more stable. I will add some 3rd level flooring and joists which with further stabilize the wall.
Like the lower level brackets, those on the upper level of the long wall are one floor plank thickness too high. I made the same mistake on the 2nd level brackets and broke them off and reglued them to the proper height. I didn't do that with the 3rd level. They were glued too well.
So to make the floor level without much fuss I will just take a notch out of the joists so they align properly. I'll do that tomorrow. The joists in this pic are not glued.
