This morning I routed some slots in the corner to accept some 3/8" rod which will act as the rope which will 'hang' the sign from the corners. In actual fact the sign will be suspended from the two pieces of tubing which stick out of the back. The rest of the frame dropped into the routed slots in the middle. This makes the sign well able to handle anything it might be subjected to in the theme park environment. The back and front of the sign were then laminated together with the steel frame in the middle.
We then lifted the sign into position and permanently welded it there. I was pleased with the result. We will now finish welding up the armature of the tree and get to the sculpting process. Stay tuned...
