The full-scale Grotto cut out of 1/8", 1/4" and 3/8" stainless steel sheets will need more tolerance between the components as we incrementally assemble the structure. It won't be possible to weld a part without checking and tweaking the alignments a few cells away. We've devised a system of holes that will allow for fasteners to be placed to hold the connectors to the ribs temporarily. As adjustments are made to the braked angles, the fasteners are tightened and contact is made. Two other holes in the connector will provide easy access to perform a basic plug weld. Fasteners are removed, welds ground and the entire structure will be glass-bead sandblasted, erasing the trace of the assembly process.
